Our goal is to determine how proteins function in space and time in the context of complex cellular networks.
We focus on chemistry-driven approaches to manipulate protein structure beyond what is feasible with standard genetics.
In particular, we use semi-synthetic light-activatable proteins as biophysical probes to investigate protein mechanisms
inside living cells. Areas of interest include the important but poorly understood process of protein S-acylation, signal
transduction, and protein trafficking.
