Margaret Kalcic 

Margaret Kalcic’s research is in the area of watershed hydrology with a particular focus on water quality in agricultural regions. Before taking a faculty position at OSU she completed her undergraduate degree focused on Bioengineering at F. W. Olin College of Engineering, her Master’s and Ph.D. in Ecological Engineering at Purdue University, and a postdoc at the University of Michigan. Since 2013 she has worked on decision support tools and watershed modeling in the western Lake Erie watersheds to encourage policy- and agricultural decision-makers to incentivize and adopt effective conservation measures to tackle Lake Erie’s nutrient goals. She has a broad and applied research program spanning water quality modeling, geospatial analysis, stakeholder engagement, ecosystem services, and field-scale monitoring of conservation effectiveness.



Post-doctoral researchers


Grey Evenson’s research focuses on watershed hydrology and he has a particular interest in the development of new models and tools to improve watershed health. Prior to joining the Kalcic lab, Grey served as an Oak Ridge Institute for Science and Education Research Fellow with the US EPA’s Office of Research and Development and as a Postdoctoral Fellow within the Department of Forest Resources and Environmental Conservation at Virginia Tech. In his time with the US EPA and Virginia Tech, Grey developed an expertise in the application of watershed-scale hydrologic models to simulation the hydrologic and biogeochemical impacts of wetlands. Grey holds a Ph.D. in Geography from Ohio State and has expertise in watershed hydrologic modeling, wetlands, geographical information systems, and computer programming languages.



Xioqiang Liu’s research interests are broadly across the field of soil and water conservation, and his current research focuses on water quality of streams, primarily in agricultural settings, and on agricultural best management practices to address nutrient leaching out of agricultural systems. He received his undergraduate degree in agricultural education at Shandong Agricultural University, his master’s degree in geology from Indiana University-Purdue University Indianapolis, his Ph.D. in ecology at Institute of Botany, the Chinese Academy of Sciences, and Postdoctoral training in agricultural engineering. Beside research, he is interested in teaching and learning, and he believes in the importance of self-learning and self-improvement. He has co-taught and taught Environmental Hydrology courses in the Food, Agricultural, and Biological Engineering department, and he has assisted Dr. Andy Ward in teaching Watershed Hydrology and Stream Geomorphology and Drainage and Irrigation.


Asmita Murumkar’s research interests are broadly in the field of hydro-climatology at river basin scale. Her expertise involves stochastic hydrology, hydrological modeling, data analytics, climate change assessments, remote sensing and GIS. Currently, she is working on hydrology and water quality modeling of the western Lake Erie basin in response to fertilizer applications especially during high-risk storm events.  Before, joining the Kalcic Lab, she was a postdoctoral researcher at OSU’s Byrd Polar and Climate Research Center (BPCRC). She conducted hydro-climatic modeling in an interdisciplinary project funded by NSF-CNH (

Dr. Murumkar received her undergraduate and master’s degrees in Agricultural Engineering from India. She has a PhD degree in Hydrology from Indian Institute of Technology (IIT) Roorkee (India). Besides research, she is an active member of the Postdoctoral Association at OSU.


Graduate students

Anna Apostel is a PhD student at the Ohio State University in the Food, Agricultural, and Biological Engineering Department. She received her B.S. degree in Biology at Denison University and an M.S. in Civil and Environmental Engineering at The Ohio State University working on the identification of model equifinality and uncertainty quantification in Total Maximum Daily Load (TMDL) development. Her current research focuses on Harmful Algal Blooms in Lake Erie’s Western Basin and watershed modeling of the Maumee River using the Soil Water Assessment Tool (SWAT).



Haley Kujawa is a master’s student in the Environmental Sciences Graduate Program at Ohio State. She received her bachelor’s in Biological Systems Engineering with a minor in green engineering from Virginia Tech. Her current research focuses on using the Soil and Water Assessment Tool (SWAT) to assess nutrient loadings to  Lake Erie – a main driver of harmful algal blooms. Her career interests lie in using research to inform environmental policy.






Elizabeth Callow is a master’s student in the Food, Agricultural, and Biological Engineering (FABE) Department. Elizabeth graduated from The Ohio State University with a B.S. in Agriculture, focusing on Agronomy, and a minor in Engineering Sciences. Her research focus is evaluating stacked best management practices developed to reduce nutrient loads in agricultural drainage waters. Elizabeth is also working on developing the research group’s new water quality analysis lab. Elizabeth grew up on a family farm in Northwest Ohio and is very excited that her research is tied to that region.









Elizabeth Schwab is a master’s student in the Environmental Science Graduate Program. She received bachelor’s degrees in both agronomy and environmental science from Iowa State University. She is interested in assessing the accuracy of public perception of water quality across agricultural and non-agricultural communities, and in using this information to influence targeting and delivery of outreach and education efforts. Elizabeth is passionate about making education effective and enjoys learning about how people shape their perceptions of the environment.



Undergraduate students

Ross Candor is an undergraduate student pursuing a degree in Ecological Engineering. His work experience was with the United State Army Corp of Engineers as a part of the Missouri River restoration project. Ross also spent a summer working at Ohio State’s Stone lab as a student research lab assistant. Ross is a part of the field team responsible for ISCO water quality samples from northern Ohio. He grew up in Gahanna, Ohio which is very close to the Columbus campus.








Claudia McAllister-Peterson is from Yellow Springs, Ohio and has worked for the department as an undergraduate researcher for two years. She is a fourth year student pursuing an ecological engineering degree with a minor in studio art.
