Jason K. Keller, Ph.D.
Dr. Keller received his B.S. and Ph.D. in Biological Sciences from the University of Notre Dame (advised by Dr. Scott Bridgham). He completed a post-doctoral fellowship at the Smithsonian Environmental Research Center (advised by Dr. J. Patrick Megonigal) before joining Chapman University in 2008. Most of his current research centers on understanding anaerobic carbon cycling in northern peatlands, although he is excited to expand his work into local salt marsh ecosystems as well. He can be contacted at jkeller(at)chapman(dot)edu.
Cassandra A. Medvedeff, Ph.D.
Dr. Cassandra Medvedeff is currently an Instructional Assistant Professor of Biological Sciences at Chapman University. She received her B.S. and M.S. in Biology from the University of North Carolina at Greensboro (advised by Dr. Anne Hershey). She completed her Ph.D. in Soil and Water Science (Wetland Biogeochemistry Laboratory) at the University of Florida (under the direction of Dr. Patrick Inglett). Her research interests include understanding mechanistic regulators and interactive controls on anaerobic microbial decomposition. Her past research has focused on nutrient controls (carbon quality, phosphorus availability, ash/char fire residues) and disturbance (restoration, fire) on microbial decomposition (enzyme activity, CO2 and CH4 production) in wetlands within Everglades National Park. Her research includes both a laboratory and field based approach to answer crucial questions within the context of global climate change. A copy of her CV can be found here.
Glenn Woerndle, M.S.
Glenn Woerndle joined the lab as a research associate in May, 2016 after completing a Master’s degree in Biology: Ecotoxicology at the University of North Carolina, Greensboro. Her research interests include spatial and temporal variation in methane cycling, as well as the sources, transformations, and fate of pollutants in aquatic ecosystems. She is currently involved in all projects in the lab, and keep the place running smoothly from day to day. A copy of her CV can be found here.
Jessica Rush (Biological Sciences, Class of 2018)
Jesse as a Biological Sciences and Spanish double major who joined the lab group in the Spring of 2016. After discovering here interest in environmental science and hearing about both the lab and field work being done in the Keller lab, she knew she had to get involved. Her main focus has been studying the role of humic reduction in peatland soils. Currently, she is exploring the direct and indirect effects of temperature on humic reduction in a northern Minnesota peatland that is part of the SPRUCE project. After graduation, Jesse hopes to travel to Spain and then study medicine to pursue a career in allergy and immunology.
Emily Hanna (Biological Sciences, Class of 2018)
Emily joined the Swamp Monsters in the Fall of 2016. Her interest in biogeochemistry sparked after attending Chapman’s Student Research Day and listening to other students present posters on their current research. She is currently involved with experiments focused on humic reduction in peatland soils.
Kyvan Elep (Environmental Science and Policy, Class of 2017)
Kyvan joined the lab in the Spring of 2016 and has been working on a project looking at greenhouse gas fluxes at the Seal Beach National Wildlife Refuge. This site is home to a pilot project using thin layer sediment augmentation as a mitigation tool to help offset sea level rise. There is interest in exploring the climate implications of this management technique, which requires a greater understanding of the fluxes of carbon dioxide, methane and nitrous oxide from the marsh surface. Kyvan also has an internship focused on environmental education and post-graduation hopes to work as an educator in the National Park Service.
Haley Miller (Environmental Science and Policy, Class of 2018)
Haley is an environmental science and policy major who became a Swamp Monster in the Spring of 2016. She has been involved in the Seal Beach project studying greenhouse gas flux. Haley is interested in the processes of carbon storage in wetland and oceanic ecosystems, and hopes to continue to study climate science and marine ecology following her undergraduate career.
