Biography

Hannah R. Malcolm, Ph.D. joined the Department of Chemistry in 2015. She completed graduate work at Washington University in St. Louis in 2012, with Prof. Joshua A. Maurer and her post-doctoral research at UT Southwestern with Prof. Paul Bount (2012-2015). Since joining the UNF Department of Chemistry she has taught General Chemistry I (both lecture and lab) and Biochemistry I and II (both lecture and lab). She has a vibrant research program that explores how bacteria sense and respond to mechanical tension in the membrane. My research group focuses on bacterial mechanosensitive ion channels, specifically MscS (mechanosensitive channel of small conductance) and MscL (mechanosensitive channel of large conductance) as well as their homologues. We study these channels in E. coli, P. graminis, and other novel bacterial strains. We utilize several different techniques to understand how each of these channels responds to mechanical tension in the membrane.
