I'm recruiting! Looking to hire a postdoc to work on mercury methylation in cultured microorganisms, investigating the metabolic drivers of this important and enigmatic process. See details here: sites.uwm.edu/petersob/202.... Feel free to reach out to me with questions and please pass this along!

Another paper alert! This one led by my colleague Grace Armstrong at the USGS Mercury Research Lab, using seasonal sampling and mercury stable isotopes to investigate temporal trends in mercury bioaccumulation in two eutrophic urban lakes. Check it out! pubs.acs.org/doi/10.1021/...

Seasonal Stratification Drives Bioaccumulation of Pelagic Mercury Sources in Eutrophic Lakes

Increased lake eutrophication, influenced by changing climate and land use, alters aquatic cycling and bioaccumulation of mercury (Hg). Additionally, seasonally dynamic lake circulation and plankton c...

New manuscript in Environmental Science & Technology: pubs.acs.org/doi/10.1021/... We combined enriched stable-isotope incubation assays for mercury methylation and demethylation with DNA and RNA sequencing with to investigate key constraints on methylmercury accumulation in freshwater. Highlights:

Sulfate Reduction Drives Elevated Methylmercury Formation in the Water Column of a Eutrophic Freshwater Lake

Mercury (Hg) contamination of aquatic food webs is controlled in part by the formation and accumulation of toxic and bioaccumulative methylmercury (MeHg). MeHg production is mediated by metabolically ...

First shipment of supplies into the new lab! Can't wait to put these new toys to use.

I'm excited to share that today was my first day as an Assistant Professor in the School of Freshwater Sciences at the University of Wisconsin - Milwaukee! I am very excited to join the great faculty at this one-of-a-kind program, especially in my home state and a city I love.
