Environmental and Soil Microbiology
Decomposition is one of the most important functions that microbes perform in our environment. We seek to understand how microbial communities work to recycle both natural and xenobiotic inputs in terrestrial environments. Understanding decomposition and biodegradation is key to developing better solutions for waste disposal, environmental bioremediation, and predicting ecosystem response to perturbations.
Current Projects
Decomposition of Vertebrates
There is (microbial) life after death. We are investigating the microbial processes of decomposition of carcasses and cadavers, to determine how nutrients are recycled in these ‘hot spot’ ecosystems.
Agricultural Plastics and Microplastics
Plastic pollution is a threat to healthy soils. Our lab is investigating the impacts of biodegradable and conventional microplastics on soil ecology. We’re also investigating the microbial mechanisms of plastic biodegradation.
Soil Microbiomes
A healthy soil has abundant and diverse microbial life. We collaborate with other scientists to investigate how agricultural practices (e.g. reduced tillage, cover cropping, native forage grasses, genetically engineered crops) influence soil microbial communities and their functions.
