Research
My research interests include systems biology of microbial communities and roles of nutrient exchange in microbial interactions and symbioses. For my post-doctoral work, I was part of a project investigating energy flow in cyanobacterial microbial mats and understanding secreted protein signatures in these complex communities. I am interested in how microbes, photoautotrophs in particular, play a role in transforming their environment and responding to change. I am also interested in integrating data using ‘omics techniques (transcriptomics, proteomics, metabolomics), stable isotope probing and novel imaging strategies.
