Postdoctoral Researchers


Colby Moorberg

Colby is now an Assistant Professor in the Department of Agronomy at Kansas State University. He is a soil scientist with interest in soil-root interactions. Colby joined the Hydro-biogeochemistry group as a postdoctoral researcher from January of 2014 to January 2015 to investigate effect of plant roots on methane oxidation in boreal wetlands in Alaska.

Mickey Jarvi

Mickey is now a Professor of Forestry at the College of the Redwoods. Mickey was part of the Hydro-biogeochemistry group as a postdoctoral research from January 2016 to August 2016. He investigated how belowground flora and microfauna interact to influence atmospheric fluxes of carbon dioxide and methane from a bog in central Alaska. 

Javier Espeleta

Javier is now a consultant in Costa Rica. He joined the Hydro-biogeochemistry group from January 2013 to August 2015. He investigated how plant hydraulic redistribution of water and nighttime transpiration influences nutrient cycling in the soil zone surrounding plant roots (i.e., the rhizosphere).


Graduate Students


Lara Pracht

Lara Pracht

Lara Pracht completed her PhD in November 2016 and is now a Laboratory Resource Coordinator at Oregon Institute of Technology. Her thesis was titled, "Arsenic contaminated groundwater: exploration of the role of organic carbon in mobilization processes and evaluation of mechanisms of arsenic sequestration by in situ treatment systems." 

Farnaz Aslkhodapasand

Farnaz completed her master's degree in November 2016 and is now a Staff Water Resources Engineer at Cardno. Her thesis was titled, "Integration of dynamic rhizospheric methane oxidation into a process-based methane emissions model."

Andrea Wong

Andrea now works for King County mapping stormwater. She was involved with field efforts researching the effects of plants on methane emissions from Alaskan wetlands while working towards her non-thesis based MSCE degree, which she completed in 2016. 


Lab Technicians


Jesse Turner

Jesse joined the hydro-biogeochemistry group in summer of 2016 after graduating from UW as an undergraduate. He spent the summer in Alaska collecting data on the relationship between climate change and methane emissions in wetlands and spent the following 9 months in Seattle analyzing the field data. He is now working for Global Leadership Adventures.

Jen Teshera-Levye

Jen was a research technician in the hydro-biogeochemistry group for two years. She left in 2013 to pursue a PhD at the University of Minnesota in the Department of Ecology, Evolution and Behavior.


Undergraduate Students


Marina Kochuten

Marina is an undergrad at UW who worked in the research group as a freshman during the 2016/2017 academic year. She helped keep the lab organized and assisted with various research tasks on multiple different projects.

Brianna Hunt

Brianna is now an environmental consultant in the Seattle area. She joined the Hydro-biogeochemistry group from August 2015 to September 2016 and an undergraduate in the Earth and Space Science Department majoring in geology, with a double degree in Anthropology. She worked on lab experiments determining methane oxidation rates in wetlands as they relate to microbial populations and activity within the rhizosphere.

Joe Ellingson

Joe received his B.S. in Civil Engineering in 2014 and is now an environmental engineer in the Seattle area. He worked as an assistant on multiple research projects in the lab during his junior and senior year of undergrad.

Hunter Brown

Hunter Brown received his B.S. in Civil Engineering in 2013. He now works an environmental engineer in the Seattle area. He worked in the Hydro-biogeochemistry group as a research assistant during his senior year of undergrad and for an additional six months post graduation. While here, he focused on the design and construction of sediment test columns, as well as calculating experiment parameters, to analyze the capacity and removal mechanisms of a PRB, to remove arsenic from contaminated groundwater

Alex Fussell
