Personal statement: My graduate school research focused on the kinetics of GTPase activation by GEFs on supported lipid bilayers and in live cells. My research has placed a special emphasis on the activation of a common oncogene known as Ras, and its interactions with the protein SOS. I have focused on developing a new technique to explore this interaction at the resolution of single activation events, as well as discovering the mechanism for a small molecule drug that targets the binding site between these proteins. Additionally, I have explored how oncogenic Ras mutations impact the Ras/SOS interaction in conjunction with an undergraduate researcher. Finally, I have explored the regulation of membrane binding for Arf and its GEF ARNO, another membrane-binding signaling protein that functions in lipid morphology and trafficking.


I have also been involved in science outreach throughout gradschool, and my volunteerism was highlighted here.
