Areas of Interest
Cytoskeletal dynamics, cell motility, mechanotransduction, endothelial mechanobiology
Extracellular stimuli in the form of dynamic or static mechanical cues influence cell behavior by physically altering a cell’s cytoskeleton. Cytoskeletal activation directs transcription that alters cell phenotype and function, collectively termed mechanotransduction. However, mechanotransduction does no proceed exclusively from the extracellular matrix (ECM) to the cytoskeleton to the nucleus. In my work I intend to uncover a mechanism by which mechanotransductive transcription tunes the cytoskeleton, to promote endothelial cell migration. My proceeding work will delineate the molecular mediators of mechanotransductive feedback and perturb this pathway by altering ECM rigidity to better understand how mechanotransductive transcription enables cell motility.

Devon joined the McKay Orthopaedic Research Laboratory in the summer of 2017 and is currently working toward his graduate degree in Bioengineering for the University of Notre Dame. When he is not busy looking at cells, he spends his time binging TV shows, cooking, eating, and lifting weights (but only in that order).
