Research Interests:

  • Geomicrobiology


Research Overview:

My research focuses primarily on the microbiological cycling of environmentally relevant trace metal(loids) including As, Sb, Se, Cr and U. My interests include novel microbial metabolisms involving metalloids that permit bacterial life at extreme conditions of salinity, temperature, and alkalinity. I also study how microbiologically mediated reactions affect the fate and behavior of these toxic trace metals in freshwater settings. 
In addition to geomicrobiological processes related to toxic trace metals and metalloids, I am also interested in food web systematics of biologically sensitive elements such as As, Sb, and Se.


Current Research Projects :

Microbiological cycling of antimony
Arsenic geomicrobiology in extreme environments
Biogeochemistry of arsenic and humic substances in the Blackfoot Disease endemic area of Taiwan
Aquatic food web behavior of As and Sb from contaminated mine tailings
