Areas of Interest

My long-term career goal is to explore the role of the membrane microenvironment in the organization, intracellular dynamics, and signaling of GPCRs. I am currently studying the mechanistic basis of spatiotemporal control of GPCR subcellular organization and signaling using a combination of quantitative cell biology, biochemistry, and forward genetics.
