Junyi Duan is a second-year Ph.D. student in the School of Construction Management Technology at Purdue University. His research interest is employing computer-based technologies to investigate the responses of infrastructure that is vulnerable to natural hazards. He is currently working on an IISG-funded project to efficiently promote infrastructure resilience in the Lake Michigan region.


Due to global climate change, extreme weather events like floods are becoming more frequent. Climate change results in higher Lake Michigan water levels, along with stronger winds and heavier storms, which exacerbates coastal damage. In the last two years, more than 200 coastline communities have spent $878 million repairing damages caused by natural hazards. The spending on repair won’t stop there − it is estimated that shoreline municipalities in the Great Lakes region will spend approximately $2 billion in the near future to restore public infrastructure that has been damaged by recent floods and erosion.

Imagine an old bridge to your house facing relentless storms and floods. You would have some worries, right? Junyi Duan is aiming to understand how different infrastructures handle these disasters. He is tackling the challenge of how to make our coastal communities more resilient to these impacts in the Sustainable Infrastructure and ManUfacturing Lab, supervised by his advisor, Chengcheng Tao, a Purdue University civil engineer and director of the lab.

Duan is integrating fluid-structure interaction modeling and artificial intelligence (AI) algorithms to decipher how floods affect infrastructures and communities. “It’s like predicting the future, not to predict doom, but to prepare and enhance the safety of our coastal areas,” said Duan.

The first step on his journey was learning from the past. Duan collected historical records to reveal how floods impacted various places around southern Lake Michigan. This information acted as a guide, steering him toward creating new models. This virtual testing helped him to understand the potential impact of floods and storms on coastlines.

The next step involved creating a powerful two-stage model. First, a physical model combining computational fluid dynamics analysis and finite element analysis was used to assess the flood impact on infrastructure as well as the structural response, respectively. This step helped Duan understand how natural hazards impact infrastructure. Preliminary work involved simulating the effects of floods on bridge infrastructure, which provided valuable insights into structural weakness.

Duan presents his research at the ASCE INSPIRE conference with his advisor Tao.

In the second stage, Duan introduced artificial intelligence and machine learning algorithms. “These algorithms are the secret sauce, crunching big data from the physical model and historical records,” he said.

The result is a comprehensive data-driven model that not only simulates potential flooding damage but also predicts the risk tendencies of critical infrastructural components. The model goes beyond simulations, offering suggestions to reinforce infrastructure, resist floods, and mitigate impacts on southern Lake Michigan coastal communities.

“This stage is crucial for stakeholders looking to make informed decisions about infrastructure types and designs suitable for the coastal area,” said Duan.

You might be wondering, why should this research matter to you. “Imagine living in a coastal community knowing that your home, your school, and your favorite spots are better prepared to face whatever nature throws your way,” said Duan. “Understanding potential hazards and reinforcing infrastructure isn’t just about avoiding damage; it’s about creating a safer, more resilient environment for everyone.”

The outcomes of this study have been presented at three American Society of Civil Engineers (ASCE) conferences and published as five conference papers. In addition, Duan and Tao worked with Purdue Science K-12 Outreach and filmed an educational video about flood hazards that will be posted on YouTube as part of Purdue’s Superheroes of Science series.

“Over the past two years, I have collaborated on research focused on the Great Lakes area, an ecosystem that sustains over 100 million people and harbors approximately 3,500 species of plants and animals. I admit that I cannot stop global warming or alleviate extreme weather events,” Duan said. “However, my aspiration is that the findings from our research will benefit shoreline residents and municipalities, contributing to the mitigation of economic, physical and ecological losses.”

As Duan charts the course through this research journey, he is not just contributing to scientific knowledge. He aims to pave the way for a safer tomorrow.

Meet our Grad Student Scholars: Kathryn Mudica

January 22nd, 2024 by

Meet Our Grad Student Scholars is a series from Illinois-Indiana Sea Grant (IISG) celebrating the students and research funded by our scholars program. To learn more about our faculty and graduate student funding opportunities, visit Fellowships & Scholarships

Kathryn Mudica is a Ph.D. candidate at Indiana State University. Her dissertation focus has been biogeochemical research in trace metal pollutants in freshwater using biotic indicators. As a water-ecosystem scientist, she has spent much of her time in the field, understanding aquatic systems and river ecology. This work has taken her to more than 50 of Indiana’s creeks and streams collecting crayfish and other biotic indicators. She has also traversed the 500 miles of the Wabash River, researching water quality in this vital watershed. Her expected graduation date will be the summer of 2024, after which she hopes to continue to spend her days wading in Indiana’s rivers and creeks and researching water quality. 


Streams and rivers are among the most valuable resources humans utilize, but a freshwater system is only as healthy as the organisms that rely on it. Freshwater systems are particularly vulnerable to the environmental persistence of biologically available mercury due to the methylation of elemental mercury. Anthropogenic activities such as coal combustion, mining, petrochemical production, and other industries have altered the pre-anthropogenic cycle of mercury, including mercury speciation. These activities have made mercury biologically available in unnatural concentrations. Once emitted, the biogeochemical cycle of mercury involves atmospheric transport, deposition to land and waterways, and revolatilization, continuing to accumulate despite reductions in emissions. Many coal-fired power plants in Indiana continue to release as much as 2,174 pounds per year, continuing to add mercury to the environment. While these power plants conform to federal regulations, Indiana as a state has not imposed state-specific regulations on the output of mercury to protect the state further. This is particularly troublesome as Indiana relies on coal for more than 50% of its energy production. It is home to 13 operational coal-fired power plants, ranking third in the nation.

Healthy aquatic ecosystems play a significant role in creating and supporting communities. Monitoring, maintaining, and improving healthy waterways can be challenging where historic industries pollute these systems with long-lasting contaminants. Major rivers and resources like Lake Michigan are monitored, but smaller creeks contribute to water quality while also being temporary repositories for pollutants. These creeks and streams can be difficult to monitor and assess for water quality due to limited stream flow and difficult accessibility. Unfortunately, these same water systems can play a significant role in the input of metals and other pollutants into our major waterways. An economical and reliable approach to determining water quality in these areas would be to identify reliable sentinel species that are endemic, easily identified, and respond in a quantifiably significant way to metals in the environment. Similar approaches using macroinvertebrate assemblages have been used successfully in citizen scientist programs and bioblitzes. However, these indices can be complicated, seasonal, and difficult to assess without identification bias. As an alternative, this research proposes, a one-organism approach as a biotic indicator, by documenting mercury in crayfish species and their environment to determine a species-specific response to mercury.

Often interacting as suspension feeders, crayfish interact with the water column continuously through brachial respiration as well as external filtering using their antennae to glean particles from the water. More aggressive crayfish species likely act as predators, moving out of safety zones to actively hunt for more substantial protein sources. These strategies vary not only by the creek but also by species. Too often, generalized responses of organisms such as order or family are used as indicators to assess the impact of mercury. While these general assessments are convenient, they do not take into consideration the varied life strategies that take place on a species level.
Indiana has a diverse range of crayfish species. Historic survey data revealed 22 known species exist throughout the state, with 11 of these belonging to the genus Faxonius. This diversity makes Indiana an excellent study area to determine species’ response to mercury in Indiana creeks.

Faxonius rusticus (Rusty crayfish) are an aggressive invasive species in the Little Calumet-Galien Watershed, displacing native crayfish.

For Kathryn’s project, crayfish samples, water samples, and sediment samples were collected in several creeks in the Little Calumet-Galien Watershed representing a variety of environmental exposures. She hypothesized that crayfish’s environmental interactions as omnivores and biotic engineers place them in a unique environmental niche, making them a reliable sentinel species. By testing and comparing the bioaccumulation of metals in crayfish tissue, water, and sediments, to dominant species, average crayfish size, and population density, we can reliably predict creek health for metals based on the specific crayfish species found. Along with the determination of crayfish as a sentinel species, this study method could be used to create community outreach and citizen science projects in alignment with the IISG Mission of creating an environmentally literate population. This research project will attempt to broaden our understanding of metal transport in aquatic ecosystems.

Meet our Grad Student Scholars: Yizhou Lin

January 9th, 2024 by

Meet Our Grad Student Scholars is a series from Illinois-Indiana Sea Grant (IISG) celebrating the students and research funded by our scholars program. To learn more about our faculty and graduate student funding opportunities, visit Fellowships & Scholarships

Yizhou Lin, a Ph.D. student in the Sustainable Infrastructure and ManUfacturing Lab at Purdue University School of Construction Management Technology, is exploring sustainable solutions for the construction material industry. Lin’s research is driven by a desire to explore innovative solutions that address this critical issue. Specifically, he is investigating the feasibility of using bottom sediments from Lake Michigan as a sustainable recycling material to enhance the efficiency of concrete use.


The cement industry is estimated to be responsible for approximately 7−8% of global CO2 emissions. The process of creating cement involves heating limestone and other raw materials to extremely high temperatures, resulting in the release of carbon dioxide.   

Lin is testing the amount of heat produced in concrete paste samples.

Concrete, as we know it, is composed of various key components, including cement, aggregates, water, supplementary materials, and additives. The additives play various essential roles in concrete mixtures, such as improving workability, reducing or accelerating setting time, and enhancing strength. Yizhou Lin’s goal is to recycle and reuse bottom sediments from Lake Michigan and evaluate the performance enhancement of the cement and concrete materials with bottom sediments added.

The increasing development of water transportation and port terminal infrastructures generates significant volumes of sediments, including dredged materials. Moreover, the Great Lakes basin faces a considerable contamination problem and harbors toxic substances that cause harm to the local ecological system. Using Great Lakes bottom sediment as an initial ingredient in concrete not only promotes the reuse of materials but also addresses the pressing contamination issue.

Lin’s research journey began with the direct collection of samples from the lake bottom. These materials need to be properly dried and sieved to select the right particle size for use as additives. At this stage, his work primarily focuses on the rheological principle (rheology is the study of flow behavior). For instance, the concept of yield stress and viscosity in fresh cement and concrete represents the point at which the paste transitions from a solid-like, immobile state to a flowable state when subjected to shear forces. He is exploring how additives can influence this yield stress and viscosity. Understanding the principles of rheology could be a game-changer in the context of introducing lake bottom sediments as potential additives. Yizhou’s mission is to decipher how various additives, such as the lake bottom sediment he’s investigating, can influence the crucial rheological behavior of fresh cement and concrete.

By understanding the rheology of fresh cement and concrete, scientists and builders can make concrete better. They can change how they mix the materials with different additives and decide how long to mix everything. This helps them handle the materials well, and make the concrete strong. Now, Lin’s research moves to the next step: how to make concrete more sustainable and durable? That’s the big question for the next phase of the study.

Lin is a world-traveling scholar. He finished his undergraduate degree in New Zealand and his Master’s in Singapore.

To find the best way to use sediment from the lake in concrete, Yizhou is creating a computer model. You might think of it like a video game that lets him see how different materials affect the concrete. He’s testing a wide variety of measurements, like how thick the concrete gets, how strong it is, and how it affects the environment and cost.

Lin isn’t doing this all by himself, but rather using advanced computer algorithms to help him.

“These algorithms are like super-smart helpers that can look at a lot of information and figure out the best ways to use the lake sediment in concrete,” he said. “It’s like a mix of science and computer magic that’s going to help us make construction more eco-friendly and better.

“I’m incredibly excited about the potential of incorporating bottom sediment into construction materials,” Lin added. “It’s like piecing together a complex puzzle where we gather information bit by bit, ultimately assembling the bigger picture to determine its viability.”

Lin finds deep inspiration in traveling around the world, a journey that consistently prompts reflections on the profound connections between humans and nature. This exploration leads to a greater understanding and appreciation of our planet’s diverse ecosystems and cultures.

Meet our Grad Student Scholars: Sydney McAndrews

December 14th, 2023 by

Meet Our Grad Student Scholars is a series from Illinois-Indiana Sea Grant (IISG) celebrating the students and research funded by our scholars program. To learn more about our faculty and graduate student funding opportunities, visit Fellowships & Scholarships

Sydney McAndrews is a second-year graduate student in the Center for Fisheries and Aquatic Sciences at Eastern Illinois University in Charleston. McAndrews is assessing urban and agricultural stream restorations by surveying fish and macroinvertebrate populations. She is also building food webs using stable isotope analysis to understand the effects of stream restorations on aquatic ecosystems.


Changes in landscapes have detrimental consequences for aquatic ecosystems. Historic forests and prairie lands have been converted to agriculture and urban areas throughout much of the Midwest. Agriculture is the cause of nearly half of the water-quality impairment issues in surface water across the United States. In addition, our expanding cities and increased paved surfaces lead to higher runoff, causing flash flood events and elevated levels of pollutants in streams. Urban and agricultural streams have sparse vegetation surrounding them, reducing pollution uptake by plants and increasing soil erosion into the water. These modified landscapes often force sensitive species out of streams, allowing pollution-tolerant species to invade.

To reduce the impacts of urbanization and agriculture, stream restorations are constructed to improve stream function and health. The goals of stream restoration are to emulate natural stream conditions, improve water quality, and create better habitat for species of interest. Monitoring stream restorations is crucial to determine their effectiveness, yet many projects do not assess the success of restoration after construction. Therefore, there is a gap in our understanding of stream restoration benefits to aquatic ecosystems.

Sydney McAndrews, a graduate student at Eastern Illinois University, is monitoring the success of restorations in two Illinois streams: Kickapoo Creek in Charleston, an agricultural stream, and the Saline Branch in Urbana, an urban stream. Both streams experienced large fish kills due to separate chemical spills in the early 2000s. In response, habitat restorations were completed in Kickapoo Creek in 2010, and in the Saline Branch in 2020. Both restorations included the construction of physical structures to increase habitat and reduce erosion.

To examine if these restorations improved the ecosystems, in the fall of 2022 and 2023, McAndrews and her team conducted fish and macroinvertebrate (animals without a backbone that can be seen without a microscope) sampling in the streams to measure biodiversity. In addition to collecting several species of stream fish and macroinvertebrates, the team also collected ants, spiders, leaves and algae to create a food web of each stream using stable isotope analysis.

Nitrogen and carbon isotopic values change in a predictable way as you move along the food chain.

Food web interactions can be assessed to determine restoration benefits on stream health because they link populations to the functioning of the entire ecosystem. Streams and terrestrial land are connected, and energy and nutrients move between them. The incorporation of food web analysis allows for an in-depth evaluation of energy flow and nutrient cycling through an ecosystem. Monitoring the food web provides insights into the connection between water and land and establishes a foundation for ecosystem-based management. However, few studies have looked at the effects of stream restoration on aquatic ecosystems.

Stable isotopes are a tool to measure and compare the energy flow in ecosystems and are used as a proxy for stream health due to the predictable pattern between a consumer and its diet. As the saying goes, you are what you eat; the composition of a consumer’s tissues reflects their dietary intake over time. A comparison of the consumer’s isotopic ratios in its tissues relative to its potential food sources can be used to build a food web.

The most common isotopes collected in aquatic systems are carbon and nitrogen. Nitrogen isotope composition is used to determine the trophic position of a consumer, or how far up a consumer is in the food chain. Carbon isotope composition is used to analyze the resource base of energy sources supporting the food web and can be used to determine if herbivores are consuming terrestrial leaves, aquatic plants or algae. Healthy food webs have a diverse energy base, with more terrestrial and aquatic links and longer food chains. The food web complexity in aquatic systems can be compared to each other when coupling the results of both carbon and nitrogen isotopes. By monitoring changes in the food web, we can gain insights into diet shifts of individual species or changes in the structure of the entire food web.

The goal of this research is to use the Saline Branch and Kickapoo Creek restorations as case studies for the effectiveness of stream restoration. The objectives of this study are to (1) measure changes in biodiversity of the streams as a function of the restorations, and (2) compare the food web structures of urban and agricultural aquatic communities as a proxy to stream health in restored and unrestored sections of the Saline Branch and Kickapoo Creek.

McAndrews expects to find more complex aquatic food webs in the restored areas compared to the unrestored areas. Information gleaned from this study will aid in the implementation of effective restoration techniques in urban and agricultural streams. It is critical to monitor the success of costly restorative stream treatments and to allocate funds to projects that increase the resiliency of aquatic habitats. McAndrews’ research is novel in its approach to use food webs to measure restoration success, and she hopes it will lead to enhanced stewardship of urban and agricultural streams in Illinois and Indiana.

Meet our Grad Student Scholars: Amber Schmidt

November 29th, 2023 by

Meet Our Grad Student Scholars is a series from Illinois-Indiana Sea Grant (IISG) celebrating the students and research funded by our scholars program. To learn more about our faculty and graduate student funding opportunities, visit Fellowships & Scholarships

Amber Schmidt is a second-year graduate student in the Natural Resources and Environmental Science Program at the University of Illinois Urbana-Champaign. Her research is focused on observing the development of benthic invertebrate communities on a nearshore, dynamic reef system in Lake Michigan. She hopes to connect the impacts of geological changes at the reef site to the changes in the benthic community.


The Adeline J. Geo-Karis Illinois Beach State Park, home to over 650 species of plants and animals, contains the last natural shoreline of Lake Michigan and the only area of beach ridge complex in Illinois. In 2021, an artificial reef composed of three submerged breakwaters, nicknamed the “rubble ridges,” was built as a pilot project to repair the shoreline and help prevent further erosion damage in a more natural way. The design, construction, and monitoring of the structure was funded by the Great Lakes Restoration Initiative in partnership with Healthy Port Futures, the Army Corps of Engineers, and the University of Illinois Prairie Research Institute.

Amber Schmidt is a master’s student working in the Czesny Lab at Lake Michigan Biological Station, a field station in the Prairie Research Institute. She is studying the nearshore macroinvertebrate community at the rubble ridges and comparing the results to the community at a control site located south of the ridges. The goal of this project is to provide a full representation of nearshore, benthic community changes and the geological factors that influence them when an artificial reef is introduced into a system.

Benthic invertebrates are organisms without a backbone that live in vegetation or in substrate in a body of water. Benthic invertebrates can indicate the health of a water body and are a significant food source to many organisms throughout the Lake Michigan food web including yellow perch and lake trout, both popular native sportfish.

The rubble ridges are unique due to the design, location, and natural materials used to build the reef. They consist of three ridges comprised of 2−3-ton limestone boulders piled on top of each other. Due to the high energy in this system such as wave action, storm events and currents, the ridges are expected to accumulate sand and flatten over time. This system is located close to the shoreline (approximately 300 feet offshore and 8−12 feet deep) which provides a new, unique habitat in this part of Lake Michigan, providing an extraordinary opportunity to collect both geological and biological data and observe how these two disciplines intertwine at a natural reef system.

To gather samples for this project, benthic cores, sediment cores, round goby (Neogobius melanostomus) abundance estimates, and round goby stomach content were collected at the rubble ridges site and the control site via a combination of boat-based work and SCUBA surveys. Hester-Dendy samplers were only used at the rubble ridges site. These samplers provide surface areas similar to the boulders at the rubble ridges, which allows for the sampling of encrusting invertebrates. There is no such structure at the control site, so Hester-Dendy samplers were not implemented there.

Benthic cores are collected by a SCUBA diver plunging a 3-inch core into the sand and capping it to capture the sediment. Benthic cores are collected to sample the organisms living in the sediment, while sediment cores are collected to quantify the size distribution of the sediment itself. Round goby are known to consume benthic invertebrates and are highly abundant in the rubble ridges. Round goby were sampled using minnow traps set in the ridges, and micromesh gillnets were used outside of the ridges and at the control site. These round goby were sampled to observe the invertebrates in their stomachs because the invertebrates were likely in the sediment at the two sites or encrusted on the boulders at the rubble ridges site.

Pictures were captured every 5 minutes by GoPro’s mounted on camera frames that remained in the water for 2−3 hours per sampling day to estimate goby abundance at the rubble ridges and control sites.

Scuba diving is the only means of sampling in this high energy, shallow environment; thus, safety concerns, the possibility of ice, and low temperatures makes the sampling for this study difficult. The sampling window each year for this project is brief, it occurred monthly from June through September in 2022 and 2023. Schmidt’s project is part of a 5-year monitoring effort of these structures undertaken by the Lake Michigan Biological Station and Illinois State Geological Survey, and sample collection will continue after she is finished with her master’s project.

“I worked as a technician at the Lake Michigan Biological Station when this project began in 2021. I fell in love with the project and asked if I could continue the work on the benthic invertebrate side of the study as a graduate student,” Schmidt said. “This research is helping us understand the impacts of structure introduction on Lake Michigan. Many organizations are thinking about placing similar structures in southern Lake Michigan. This project helps us to better understand the effect these structures on the benthic invertebrate communities and food webs as a whole.”

In particular, Audrey recently had the opportunity to travel to France to learn more about offshore wind energy, interact with industry, and get to know international counterparts.

Her trip included meetings in Paris with the International Energy Agency and the French Energy Regulatory Commission (Commission de Régulation de l’Énergie) and a visit to Nantes for the Floating Offshore Wind Turbines (FOWT) conference. At FOWT, she learned about the challenges and opportunities for floating offshore wind and took a boat tour of Saint-Nazaire, France’s first commercial-scale offshore wind farm, and Floatgen, France’s first offshore floating wind turbine.

With the remainder of her Knauss fellowship, Audrey hopes to continue engaging in policy and science related to climate, offshore wind, carbon storage, and other emerging energy issues. She is helping plan a technical trip to Norway for BOEM staff members to explore carbon storage sites and technology and hopes to support the U.S. delegation at the London Convention/London Protocol meeting in October.

Audrey Taylor recently finished her Ph.D. in Earth Sciences at the University of Notre Dame’s Department of Civil and Environmental Engineering and Earth Sciences. Her doctoral research and her undergraduate degree at University of North Carolina Wilmington focused on understanding climates and environments through both space and time.
