Tiffany L. Messer, PhD (Principle Investigator)

Dr. Tiffany Messer is an associate professor and Gatton Foundation Endowed Chair in the Department of Biosystems and Agricultural Engineering in the Martin-Gatton College of Agriculture, Food, and Environment. She grew up on a farm east of Winchester, Kentucky, where her love for water resources was sparked. She  joined the Biosystems and Agricultural Engineering Department at the University of Kentucky in October 2020. She holds degrees in Biosystems and Agricultural Engineering (University of Kentucky, B.S., 2008) and Biological and Agricultural Engineering (North Carolina State University, M.S. 2010, PhD, 2015). Additionally, Tiffany completed a postdoctoral appointment in the Nicholas School of the Environment at Duke University (2015-2016) to focus on ecological designs and analytical chemistry. 

Her research interests reside at the intersection of engineering, ecology, and agriculture with an emphasis on environmental biogeochemistry and water resources in human impacted ecosystems. She works specifically on identifying, tracing, and treating nutrients and emerging contaminants using ecological engineered designs (i.e., wetlands, streams, stormwater control measures). Along with being awarded over $18 million as a project investigator (PI) or co-PI in grant funding, she has been awarded the Gatton Foundation Endowed Chairship (2024-2029), NSF CAREER Award (2021), USDA AFRI NIFA Postdoctoral fellowship (2016), and the EPA STAR (2012-2015) fellowship. These grants have  allowed her to form an incredible team including graduate and undergraduate engineering and natural resource researchers that embrace inclusivity, diversity, and community, while studying designs to improve water quality in Kentucky, the southeast, midwest and beyond. Additionally, she is an active member of the American Society of Agricultural and Biological Engineers (ASABE) and the American Ecological Engineering Society (AEES).

She loves teaching and has taught GIS for Water Resources (junior-graduate level), Engineering Computer program (freshman level), Constructed Wetlands  (junior-graduate level), Soil and Water Engineering (junior-senior level), and Engineering Technical Writing (graduate level) courses. Most importantly she enjoys hearing about student experiences, connecting students with employers, and guiding students to reach their career dreams.

In her free time, Tiffany enjoys spending time with her family, which include her husband (Patrick), sons (Elliott (11) and Raymond (8)), and dogs Oliver (13) and Phoebe (2). She also enjoys hiking, art projects, traveling, and visiting the family farm.

William Rud
(PhD Student/ Lab Manager)

William Rud is a PhD student in Biosystems and Agricultural Engineering at the University of Kentucky. He is from Smiths Station, Alabama where he lived until moving to Auburn for his undergraduate degree. William obtained his Bachelor of Biosystems Engineering from Auburn University before moving to Kentucky to start his research and degrees on water quality, ecosystems, and emerging contaminants. His research focuses on the impact, fate, and interactions of contaminants of emerging concern on nutrient cycling in streams, wetlands, and agroecosystems. In the future, William plans to continue his career in ecological engineering and water quality research after completing his degree. In his free time William likes to backpack, cook, canoe, and play sand volleyball.

Matthew Vincent Russell is a PhD student in Biosystems and Agricultural Engineering at the University of Kentucky. Matthew was born in McCook, Nebraska but moved shortly after to Sioux Falls, South Dakota. For his bachelor’s degrees, Matthew moved back to Nebraska and completed degrees in Water Science and in Environmental Restoration Science. He then obtained his master’s degree at UNL in Natural Resources with a specialization in Hydrology. Before Matthew began his master’s degree, he worked for one year in Omaha, NE at a civil site engineering firm as an environmental scientist I. Dr. Tiffany Messer is his academic advisor, and his research focuses on the assessment of floating treatment wetlands and their productivity when livestock antibiotics and nitrogen inhibitors are introduced. In his free time, Matthew likes to cook, play/coach soccer, camp, and spend time with his fiancée, Megan, and golden lab, Maverick.

Katherine Ristola
(PhD Student)

Katherine Ristola is a PhD student in the Biosystems and Agricultural Engineering department at the University of Kentucky. She is from Livonia, MI where she lived until moving to Lexington to complete her undergraduate and MS degrees from the University of Kentucky. For her MS, Katherine worked with Dr. Tiffany Messer to research the capabilities of wetland treatment systems to remove nutrients and improve water quality from treated wastewater treatment plant effluent and the potential impacts of bourbon stillage applied to wetland treatment systems. Katherine plans to continue her MS research with Dr. Messer and expand her research into understanding the dynamics between PFAS and wetland treatment systems. In her free time Katherine likes to spend time with her boyfriend James and their dog Zeus at parks and breweries, read, bake, cook, and spend time with family.

Caleb Stickney
(MS Student)

Caleb Stickney is from Estill County, Kentucky where he grew up on his family's tree, mushroom, and cattle farm on the banks of the Red River. He graduated from Harvard University in 2021 with a degree in Environmental Engineering, worked for a time as a Water Engineer in Lexington, and is currently pursuing an MS in Biosystems and Agricultural Engineering under the direction of Dr. Tiffany Messer. His research focuses on the impact of nanopesticides on nutrient cycling and water quality in agroecosystems. In his free time Caleb enjoys spending time on the farm, caving, kayaking, and playing the banjo.
