Erik Hobbie, Laboratory Director

Erik Hobbie, Director

I am a Research Associate Professor at the Institute for the Study of Earth, Oceans, and Space and am also affiliated with the Department of Natural Resources. I use stable isotopes at natural abundance levels to understand carbon and nitrogen cycling in forest ecosystems, with a particular focus on the interactions between mycorrhizal fungi and their host plants. My webpage includes more information about my research and publications.

Janet Chen, Postdoctoral Associate and Laboratory Manager

Janet Chen, Postdoctoral Associate

Janet received her Ph.D. Degree at the University of Wyoming. Her research investigated plant nitrogen availability, acquisition and allocation for a variety of mixed grass ecosystems across North America using a combination of molecular and stable isotope techniques. She has been with the UNH Stable Isotope Laboratory since 2013.


Andrew Ouimette, Research Scientist

Andy Ouimette

Andy is a Research Scientist at the Earth Systems Research Center and a doctoral student in the Natural Resources and Earth Sysems Science (NRESS) PhD program. He received his M.S. Degree in Geology and worked as laboratory manager of UNH Stable Isotope Laboratory from 2004 - 2013. Prior to working at UNH, Andy was part of the USGS Volcano Hazards Team in California.


Alison Magill, Project Manager

Alison Magill, Project Manager

Alison is a project manager working with the Hobbie Group to oversee various research projects and collaborations. She received her MS in Forest Ecology and BS in Soil Science from the University of New Hampshire. Previously she worked as the Research Scientist responsible for site and data management of the Chronic Nitrogen Amendment Plots at the Harvard Forest LTER.

Alumni Personnel 

Francesca Scandellari

Dr. Scandellari was a Postdoctoral Fellow working on a joint research program with Dr. Robert Mitchell at the Joseph W. Jones Ecological Research Center in Ichauway, Georgia. She studied the role of ectomycorrhizal fungi in the carbon cycling of longleaf pine-wiregrass savannahs. She focused on determining the carbon isotope (d13C) patterns of soil microbial fatty acids to obtain information about the carbon sources and metabolic status of mycorrhizal fungi. She is currently faculty at the Free University of Bozen-Bolzan.

Matt Vadeboncoeur

Dr. Vadeboncoeur was a Ph.D. student under Dr. Hobbie, who's research used stable isotopes and other techniques to better understand the role of mycorrhizal fungi in forest biogeochemical cycles, as well as possible interactions with global change and human management of forest ecosystems. Matt is currently a Postdoctoral Researcher with The UNH Ecohydrology Laboratory.
