Microorganisms, especially the bacteria, have amazing abilities to withstand disruptive and toxic conditions, such as those presented by human pathologies and chemical exposure. My program is interested in how we can use these abilities to mitigate and restore essential system functions.  

Research in my laboratory combines conventional, molecular and biochemical approaches to studying the microbial ecology of unique and disturbed systems, while striving to apply laboratory research findings to real-life applications. My program is student-oriented in both the laboratory and classroom, and my goal is to use microbiology to help students respond to the emerging societal needs. 

Current projects

•  Elucidation of the mechanism of cadmium-resistance in a new species of the bacterium
   Pseudomonas
•  Elucidation of identity and functionality of bacterial communities associated with 
   pediatric eczema
•  Determination of the functional roles of bacteria associated with a rare, metal-
   impacted wetland fen system
•  Identification of bacterial community profiles indicative of environmentally-associated 
   metal toxicity
