His research interests are in solving grand challenge problems in the broad areas of health and energy through the use of micro/nano systems technologies. His work in these areas has focused on the development of in vivo like in vitro systems through microfluidic lab-on-a-chip technologies (e.g., organ-on-a-chip & microphysiological systems, developmental neurobiology models of the central nervous system, blood-brain-barrier-on-a-chip, gastrointestinal tract-on-a-chip, high throughput live cell arrays), development of high throughput single-cell physio-chemical analysis platforms, and development of microbial systems as biorefineries for bioelectricity and biofuel production while simultaneously utilizing wastewater.
He has co-authored more than 80 peer-reviewed publications and has received funding from the Bill and Melinda Gates Foundation, National Institutes of Health (NIH), National Science Foundation (NSF), Defense Threat Reduction Agency (DTRA), United States Department of Agriculture (USDA), U.S. Army Corp of Engineers, Qatar National Research Foundation (QNRF), and several other international sponsors and private companies. He currently serves as the editorial board member of the journal PLoS ONE and as an associate editor for the journal Biomedical Microdevices.
