Overview of Research Group

The Hydro-biogeochemistry research group works to advance mechanistic understanding of subsurface flow and biogeochemical reaction processes that impact water and food quality and influence global climate change; mechanistic understanding of these processes is required for the development of sound management strategies that protect human and environmental health. We address these topics by working at across vastly different spatial scales — from the scale of an individual plant root up to the field and regional scales — and by using a combination of complementary techniques, including fieldwork, laboratory investigation and numerical modeling. We currently have three focal areas: 1) arsenic contamination of groundwater and surface waters, 2) arsenic contamination of rice, and 3) plant-mediated exchange of water and carbon between the land and atmosphere.


November 14 2016 - Congradulations to Farnaz Aslkhodapasand for successfully defending her Master's thesis! She will be working as a Staff Water Resources Engineer at Cardno.

November 1 2016 - Congradulations to Lara Pracht for successfully defending her dissertation on "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"! With her new PhD in hand, Lara already has a job lined up as a Laboratory Resource Coordinator at the Oregon Institute of Technology. We wish her the best of luck in this exciting new opportunity.

September 1 2016 - Good luck to Mickey Jarvi, former post-doctoral researcher in the lab, with his new faculty position at College of The Redwoods!

March 11 2016 - Congratulations to Bobby Ardissono, an undergraduate researcher in the lab, for winning a Mary Gates Research Scholarship!

February 28 2016 - Congratulations to Becca Neumann (group PI) for winning a UW Innovation Award.

January 29 2016 - Congratulations to Nick Waldo, a PhD student in the lab, who has won a Future Leaders in Science Award from the Soil Science Society of America. Nick will be travelling to Washington DC in March for science policy training and meetings with Seattle's congressional delegation.

January 10 2016 - Welcome to our new post-doctoral researchers, Pam Barrett and Mickey Jarvi! These scientists come to the Neumann lab with backgrounds in oceanography and forestry, respectively, and we look forward to the contributions their unique skill sets bring to our research group.

January 1 2015 - Good luck to Colby Moorberg, former post-doctoral researcher in the lab, with his new faculty position at Kansas State University!
