Professor Wilhelm's vitae 

 

 


Research in the Wilhelm lab focuses on the interactions of microbial communities with the environment and in turn how the environment shapes microbial communities. Scientists at all levels work to resolve the synergies between microbial communities and biogeochemical cycles in lakes and ocean systems around the globe. Lab members use biomolecular tools - DNA and RNA sequencing, metabolomics, and PCR-based quantitative analyses - to study viruses, bacteria, cyanobacteria and algae. Currently the laboratory has a specific focus on virus ecology, toxic cyanobacterial blooms and the development of quantitative molecular tools for microbial ecology.

Congrats to Brittany Zepernick for a best paper award at The ISME Journal.   A synopsis of the paper can be found here.

Nov 2025

Students working in Meads Quarry found a toxic cyanobacterial bloom in 2024 that turned the waters pink. That story and the potential role of urea in driving such blooms is now out.
