Biography

Research

My research interests include systems biology of microbial communities and roles of nutrient exchange in microbial interactions and symbioses. I lead a DOE-OBER funded Scientific Focus Area (the µBiospheres SFA, link below) focused on understanding host-microbe interactions in bioenergy relevant systems. The project seeks to uncover context-dependent regulation of these microscale interactions and their systems-level consequences. I am interested in integrating data using stable isotope probing, high-resolution imaging mass spectrometry (nanoSIMS), and ‘omics techniques (transcriptomics, proteomics, metabolomics), and working with computational modelers to gain a predictive understanding of complex environmental communities.
