Rebecca North, Ph.D.

Rebecca is an emerging researcher in aquatic ecology and biogeochemistry, with expertise on nutrient and algal dynamics in water bodies. She has just left the great white North and has recently joined the School of Natural Resources at the University of Missouri as an Assistant Professor of Water Quality. 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. Her postdoctoral fellowship at Trent University, Ontario, Canada facilitated the expansion of her work to include the watershed, where she examined non-point sources of nutrient loading to a large lake. Her most recent work as a Research Associate with the Global Institute for Water Security at the University of Saskatchewan, Saskatchewan, Canada has been focused on light-nutrient interactions in a large reservoir and the importance of winter processes.

Dan Obrecht

Dan started working in the limnology laboratory as an undergraduate in 1990. He received his BS in 1993 and his MS in 2010, both through the Department of Fisheries and Wildlife Sciences at the University of Missouri. As an undergraduate, he helped establish the Lakes of Missouri Volunteer Program; a successful program that is still engaging Missourian’s in the monitoring of reservoirs across the state. He has been the limnology laboratory manager since 2001. Away from work, Dan enjoys the outdoors and hopes to one day perfect his fly casting.

Tony Thorpe

Tony Thorpe earned his M.S. in Fisheries and Wildlife at the University of Missouri in 2004 by correlating heterotrophic bacterial abundance with measures of trophic state at regional and global scales. He has been full-time coordinator of the Lakes of Missouri Volunteer Program since 2001. Visit the LMVP website via the link below for more information

Carol Pollard

Carol Pollard graduated from the University of Colorado-Boulder with a BS in Mechanical Engineering. After a career in engineering she returned to school, obtaining an MS in Limnology from the University of Missouri-Columbia. She in now technician in the Limnology Lab at the University of Missouri.

Postdoctoral Fellows

Dr. Ruchi Bhattacharya

Dr. Ruchi Bhattacharya is the recent recipient of the MU Postdoctoral Fellowship for Faculty Diversity. She is an aquatic biogeochemist and paleo-limnologist. Her research focuses on understanding the ecological, biogeochemical and hydrological responses of aquatic ecosystems, across spatial scale, in relation to anthropogenic alterations and hydro-climatological changes. In particular, her research attempts to reveal underlying physical and biological processes that exert strong control on ecology of lake and river ecosystems. The key questions she focuses on are: a) How does the interaction between landscape characteristics and hydrological variability influence the nutrient and water fluxes from catchment to lake? b) What is the ecological response of lake ecosystems to this influx?

PhD Students

Jacob Gaskill

Jacob recently joined the Limnology Lab as a PhD student under the tutelage of Dr. Rebecca North. He is interested in applied limnology issues such as harmful algal bloom management and understanding how invasive species introductions influence our lentic ecosystems. Jacob received his BS from the SUNY College of Environmental Science and Forestry (Syracuse, NY) and his MS from Grand Valley State University (Grand Rapids, MI) where he studied the relationship between invasive dreissenid mussels and the cyanobacteria Microcystis in a low-nutrient lake.

Masters Students

Erin Petty

Erin graduated summa cum laude from the University of Missouri in May of 2017 with a B.S. in Soil, Environmental, and Atmospheric Science, and a certificate in Geographic Information Systems (GIS). She recently joined the Limnology Lab as a laboratory technician, and will continue with us in the fall as she begins pursuit of a M.S. in Water Resources. Previously employed at the Missouri Department of Conservation as an assistant GIS specialist, Erin has a background in both terrestrial biogeochemical processes and GIS analysis. She is interested in understanding how the occurrence and persistence of cyanobacteria in lentic systems are being influenced by landscape modification, eutrophication, and climate change within the spatial context of Missouri."

Undergraduate Researchers

Matt Sauer

Matthew is a junior Fisheries and Wildlife student at the University of Missouri. He is interested in aquatic ecology, especially looking at how humans are impacting these ecosystems. He has been working for the Limnology Lab since February of 2016 and was a part of the SLAP field team during 2016 and is looking forward to returning for the 2017 summer. Matt is currently working on an undergraduate research project called LugNuts, an international collaboration research project focusing on developing skills and giving students real world experience. Matt is currently slated to graduate in December and hopes to spend some time traveling while applying for graduate schools.

Jaylen Bragg

My name is Jaylen Bragg, and I am a junior studying Environmental Science with an emphasis in Hydrology. I have a strong interest in how hydrological processes impact nutrient loading in freshwater ecosystems. I currently work in the Limnology lab as an undergraduate research assistant, and I will work in the lab full time during the summer of 2017. After obtaining my B.S. in Environmental Science, I plan on attending graduate school to obtain my M.S. in Environmental Science and continue researching lakes and freshwater ecosystems.

Jannice Newson

Jannice Newson is a senior majoring in Soil, Environmental, and Atmospheric Science. She is interested in water quality, aquatic plants, and green infrastructure. She is a McNair Scholar and will begin working with Dr. Rebecca North on an undergraduate research project in Fall 2017. Currently, Jannice serves as a CAFNR Recruitment Intern and Secretary of Mizzou Black Women’s Initiative (MBWI). She has contributed to various projects including shoreline restoration evaluation at the Chicago Botanic Garden and recirculating aquaculture systems at the University of Michigan. After graduating from MU, she plans to obtain a M.S. in Environmental Science.


Kyle Carson

Kyle is a senior majoring in Soil, Environmental and Atmospheric Science with a focus in Water Quality. He is interesting in how watershed management affects nutrient loading in lakes and reservoirs and is currently working on an internship on bathymetry. He started working for the lab in August of 2017 and is looking forward to being part of the SLAP team for the summer of 2018. He will also be studying abroad this winter in Thailand with the trip focusing on coral reef biodiversity and restoration.
