Rebecca is an aquatic ecologist and biogeochemist, with expertise on nutrient and algal dynamics in water bodies. Sheleft the great white North andjoined the School of Natural Resources at the University of Missouri in 2016. Her PhD in limnology was obtained at the University of Waterloo in Ontario, Canada where she worked on eutrophication issues in the African and North American Great Lakes.
Andrea Price, Ph.D., Senior Research Specialist
Andrea Price earned her PhD in 2016 from McGill University in Physical Geography. She completed both her MSc and BSc from the University of Victoria in Earth and Ocean Sciences. Her graduate studies focused on using organic-walled microfossils as indicators of water quality in coastal regions around North America. She is currently a Senior Research Specialist in the North Limnology Lab and the Project Manager for the Statewide Lake Assessment Program. She moved to Missouri in 2022 and is enjoying getting to know Missouri’s lakes and cycling paths.
Lorena Silva, Postdoctoral Fellow
Lorena Silva is a postdoctoral fellow in the School of Natural Resources at the University of Missouri and in the Horn Point Laboratory at the University of Maryland Center for Environmental Science. Her research interests include water quality, plankton dynamics, and ecosystem ecology. The overarching goal of her research is to understand how global change issues (e.g., eutrophication, land use change, pollution, urbanization, and climate change) impact the biodiversity and functioning of aquatic ecosystems using observational, experimental, and modeling approaches in habitats that range from streams and ponds to large lakes and river systems. She received her M.Sc. in the Department of Biology at the Federal University of the State of Rio de Janeiro and her Ph.D. in the Department of Ecology at the Federal University of Santa Catarina, both in Brazil. Her current work has been focused on how earth-observing satellite data can better inform critical links between the biogeochemical and optical properties of inland waters. The results of this project will help target chlorophyll hotspots to track cyanoHABs across the state of Missouri.
Zohreh is a Ph.D. student in the Water Resources program of the School of Natural Resources under the supervision of Dr. Rebecca North. She received a B.S. of Fisheries Sciences from Isfahan University of Technology and a M.Sc. of Aquatic Ecology from the Gorgan University of Agricultural Sciences and Natural Resources, Iran. Prior to joining MU, she worked as a Data Analyst at the Soil and Water Research Institute. Her past research consisted of the studying ichthyoplankton and phytoplankton communities in Coastal ecosystems as well as host-parasite relationship in stream fish species. She is going to investigate the impact of flood on Cyanobacteria Harmful Algal Blooms (CyanoHABs) and the associated toxins in Missouri lakes and reservoirs. Outside of the lab, she enjoys cooking, hiking, and hopefully exploring the nature of Missouri.

Amelia is a graduate from the University of Missouri in Natural Resources, with an emphasis in Fisheries and Wildlife. She joined the lab in Fall 2024 and has been working mostly in the lab as well as in the field. She is interested in a career in outdoor education and outreach, and really appreciates the versatility and new skills this job has come to offer. Outside of the lab, Amelia enjoys hiking and learning more about Missouri’s resources.
Jacob Skipton,Undergraduate Student
Jacob Skipton is a senior studying Natural Resources Science and Management with an emphasis in Fisheries and Wildlife. He joined the Limnology lab in Fall 2022. He is interested in anything outdoors and loves to travel. Jacob plans to pursue a career in conservation after graduating from MU.
Kari Leake,Undergraduate Student
Kari is a senior at Mizzou set to graduate in the spring of 2025 with a B.S. in Natural Resource Science and Management with an emphasis in Human Dimensions. She joined the MU Limnology Lab in the 2024 field season and has been working on sampling for the SLAP project, deploying buoys for the Thin Ice project, and working with postdoctoral fellow Lorena Silva to gather TRIOS data measuring radiance in lakes to help satellites identify algal blooms. Since joining the lab, she has become very interested in water quality and hopes to continue working or studying in the field.
Thalia Huebner,Undergraduate Student
Thalia is a senior at Mizzou graduating in Winter of 2025 with a Bachelor's of Science in Biology. She joined the lab in January of 2025 and works in and out of lab doing field work, analyzing nutrients from water samples, and prepping for the Thin Ice, SLAP, and ROSS projects. After graduating she will relocate to Canada to pursue a Masters in Marine Biology.
Tobi Miller,Undergraduate Student
Tobi is a senior studying Natural Resources Science and Management with an emphasis in Forest Services. Tobi worked for two summers with the Rocky Mountain Conservation Corps and recently joined the limnology lab as a member of the field team in Fall 2025. Tobi enjoys hiking, rock climbing, and road tripping across the country. Tobi hopes to continue her work after graduation in environmental conservation and preservation and would love to keep working outdoors for as long as she can.
Robbie Tyson,Undergraduate Student
Robbie Tyson is senior at Mizzou studying Natural Resources Science and Management with an emphasis in Fisheries and Wildlife. He joined the Limnology lab in the Fall of 2025. In his free time, he likes to fish, hike, or do anything in the outdoors. After graduating, he plans to get his master's degree in wildlife science and continue on to work in game bird management or research.
Braydon Dickmeyer,Undergraduate Student
