Current Lab Members (listed in order of duration in the lab group)
Emily Bernhardt, PI
Emily received her PhD in Ecology and Evolutionary Biology from Cornell University in 2001 and has been a member of the Duke faculty since 2004. The core of Emily's interests are in watershed biogeochemistry, with most of her current effort invested in understanding how the ways in which people live on and use the landscape alters the structure, function and chemistry of receiving streams and wetlands.
Matt Ross, PhD student
Matt is from Colorado, where he completed his undergraduate degree in ecology and evolutionary biology at CU-Boulder. His previous research was in the aridlands of Utah, but he is now working in Central Appalachian watersheds and the Venice lagoon. Matt is currently a fellow in Duke's WISeNet IGERT program and is interested in using environmental sensing to understand ecosystem degradation and to inform ecosystem design and restoration.
Richard Marinos, PhD Student
Richard came to Duke in 2012 after graduating from Kenyon College in Ohio and serving in the Peace Corps in Cameroon. He is interested in antropogenic impacts on the nitrogen cycle. He is examining how land-use change is altering patterns of nitrous oxide emissions in the Western Pampas, Argentina. Richard is also starting to work on how calcium fertilization affects streamwater nitrate export in the White Mountians of New Hampshire. He is co-advised by Rob Jackson.
Jessica Brandt, PhD student
Jessica came to Duke after completing her undergraduate and master's degrees at The Johns Hopkins University and a year in Italy on a Fulbright research grant. She studies coal combustion residues (CCRs) - waste products that are enriched in several toxicologically significant contaminants (e.g. arsenic, selenium, cadmium) and build up in sediments. Biogeochemical factors, as they mediate the toxicity of selenium and trace metals in freshwaters, are important considerations in her work. She is co-advised by Rich Di Giulio in the Toxicology Program.

Eric Moore, Field and Lab Technician
Eric came to Duke in October of 2015 after completing his B.S. in Geology from Indiana University. While at Indiana, he worked for the Indiana Geological Survey focusing on acid mine drainage remediation and groundwater/surface water interaction. Currently, he is studying mountain top mining in West Virginia and stream metabolism across the country.
Marie Simonin, Postdoctoral Associate
Marie is from Normandy, France and came to Duke in 2016 after completing her Master’s degree at the University Pierre et Marie Curie Paris VI and her Ph.D at the University of Lyon in the Microbial Ecology Lab. Marie examines anthropogenic impacts on soil and wetland ecosystem functioning, especially on microbial functional groups involved in the nitrogen cycle. Currently, her work focuses on the impact and fate of nanomaterials in terrestrial and wetland ecosystems thanks to the funding of the Center for the Environmental Implications of Nanotechnology (CEINT).
Research Gate and Google Scholar
Andrew Pericak, Geospatial Analysis Wizard
Andrew received the Master of Environmental Management degree from Duke's Nicholas School of the Environment in 2016. He is currently using Google Earth Engine to map the yearly extent of mountaintop mining across the entirety of Appalachia since 1972.
Aaron Berdanier, Data Scientist
Brooke Hassett, Freshwater Lab Manager
After completing her master's degree at the University of Maryland where she examined stream restoration activities throughout the Chesapeake Bay watershed, Brooke was the Bernhardt lab manager from 2005-2012 and led our efforts to understand the effects of urbanization and urban stream restoration on stream ecosystem structure and function. Brooke now manages the Freshwater Lab for our lab together with three other groups within the Duke River Center.
Joanna Blaszczak, PhD student
Joanna is from Texas and comes to Duke after completing her undergraduate degree at Cornell University and a year as a Fulbright scholar in Norway. Joanna is studying the impacts of urban land use on the composition and cycling of organic and metallic contaminants in urban streams and ponds. She is co-advised by Dean Urban.
Joseph Delesantro, Field and Lab Technician
Joseph joined the lab in summer 2013 after completing his masters degree with Matt Cohen at the University of Florida. Joseph manages our urban stream research effort throughout the Research Triangle.
Steve Anderson, Field and Lab Technician
Steve joined the lab in the fall of 2014 after two years of running the Wright lab at Duke. Since receiving a B.S. in environmental forest biology from SUNY-ESF, Steve has spent the last five years in trait-based plant ecology research. He is most interested in studying anthropogenic threats biodiversity and ecosystem function in just about any context. Steve will bring his expertise in plant ecology to bear in our ongoing nanomaterials and coastal plain research efforts.
Yongli Wen, PhD student
Yongli is from Nanjing, China and came to Duke in October, 2015 as a visiting phD student. Yongli is interested in the role of Fe in the stabilization of soil C and has done much on how fertilization regime affect iron mineral-organic carbon associations in soils. She is currently working to understand how saltwater intrusion affects soil iron and biomass C stocks.
