I am a postdoc in the Department of Biophysics at Johns Hopkins University, in the group of Margaret Johnson. I am currently working on the kinetics of cargo capture during the early stages of clathrin-mediated endocytosis, as well as using kinetic modeling to assess the relative contribution of surface localization to the enhancement of enzyme activity.
Previously, I was a graduate student in the Deserno group at Carnegie Mellon, where I learned to leverage theoretical and computational tools to study lipid membranes. In my thesis work, I developed a modification of the utra-coarse-grained Cooke lipid model rendering it capable of simulating bilayers with differing tensions in the two monolayers, a state known as "differential stress". I then put this model to work investigating how differential stress alters first-order phase transitions in lipid membranes, shedding light on the recently-discovered "stiffening transition" observed in membrane simulations. I also developed a coarse-grained simulation technique (which we like to call membrane "sticky tape") to allow the simulation of asymmetric lipid bilayers with simltaneous area- and curvature-relaxation.
