Microbial interactions and functioning in soils from many different ecosystems, with the overall goal of understanding environmental factors that affect microbial community composition and how microbial community structure in turn affects ecosystem function
Examining how subsurface microbial communities change during soil formation and how microbial communities vary due to anthropogenic disturbance
Comparing microbial community composition in conventional and organic grain production in the mid-Atlantic
Investigating the community structures of freshwater tidal wetland plants and rhizosphere microorganisms in restored and natural locations in urban and suburban/rural watersheds
