August 2023.   Jenna Israel assessed climate change impacts on denitrification performance of woodchip bioreactors.  Warmer temperatures are expected to outweigh effects of intensified precipitation and shorter hydraulic residence times, leading to a net improvement in nitrate load reductions.

August 2023.  Yizhuo, Liz, and Ava traveled to the Piermont and Norrie Point Tidal Marshes to perform field sampling and measurements of hydroxyl radical production in tidal wetland sediments.  This is part of a project studying the effects of wetland salinization on the stability of carbon in tidal wetland sediments.

Higher manganese concentrations in rice paddy soils suppressed arsenic mobilization. Find out why in new research from Scott and Lena published in GCA.  Thanks to great collaborators at NSLS-II and Dale Bumpers National Rice Research Center for making this possible!

The Reid Lab celebrated the end of the semester and kicked off the summer with an outing to Atlas Bowl in Trumansburg.

9.2017: A new study on arsenic biomethylation in an anaerobic culture enriched from Mekong Delta rice paddy soil has been published in ES&T.  Key findings include the observation that anaerobes are capable of efficient arsenic methylation, despite the toxicity of trivalent methylated products, as well as a broader view of arsM diversity through a new degenerate primer pair and amplicon sequencing.

12.2016: Scott Maguffin joined the group at the beginning of December, after completing his PhD at the University of Oregon and a short stint with AGU in Washington, D.C.  He will work on the NSF-funded project “Investigating the Limits of Arsenic Methylation in the Critical Zone.”   Welcome!

12.2016: Phil was awarded a grant from Cornell’s IGERT program in Cross-Scale Biogeochemistry and Climate in support of his project: “Characterization of Nitrous Oxide Emission Hotspots and Microbial Gradients in Denitrifying Bioreactors.”  Congratulations Phil!

Philip McGuire and Sanam Anwar joined the group in August to begin work on projects related to gas transfer in denitrifying bioreactors and constructed wetlands.  Welcome!
