Biography

Dr.Karen Lloyd has completed her PhD in 2009 from University of North Carolina, Chapel Hill and presently working as Assistant Professor at  University of Tennessee.  

Research Interest

Our research integrates geomicrobiology, molecular biology, and geochemistry to determine how microorganisms influence marine geochemical cycles. The goal is to link uncultivated microorganisms to their geochemical functions and explore how these communities react to changing environmental conditions.
