Research Summary: 

Applies fundamental engineering science to microbial ecosystems, developing innovative strategies for a more sustainable agriculture and the emerging bio-based economy. Particular emphasis is on microbial processes that occur in three-phase porous media. These porous media systems are referred to variously as solid-state fermentation in the biotechnology, pharmaceutical and food processing industries; composting in the manure management and solid waste realms; ensilage on dairy and beef cattle farms; and soils in agroecosystems.
