My research foci are mechano-transduction mechanisms by which cells sense and convert environmental mechanical stimuli into biological signaling and novel nanomedicine approaches that target dysregulated mechano-sensing pathways. Cellular mechanotransduction is instrumental to embryogenesis and physiological control of tissue homeostasis; abnormal cell responses to mechanical forces promote pathologies associated with numerous human diseases. This is especially important in the vasculature, where environmental mechanical stimuli produce cellular responses in endothelial cells at arterial curvatures and bifurcations by locally disturbed blood flow to induce atherosclerosis. A similar cascade appears to be induced in acute lung injury where it is the increased cyclic stretch that is the trigger. My research program at the University of Chicago focuses on the molecular understanding of endothelial homeostasis governed by mechanical forces, with emphasis upon regulation of non-coding genome, transcription factors, G protein signaling, and genetic variance. Another major research goal is to develop innovative nanomedicine-based therapeutic strategies to treat dysregulated mechano-sensing mechanisms causing vascular diseases.
