We are interested in how the molecular machinery of the cell assembles, functions, and evolves. To tackle this problem we use electron cryo-tomography, a technique that enables us to visualize this machinery inside living cells -- to resolutions capable of discerning individual proteins.

I am co-director of the Department of Life Science's MRes in Structural Molecular Biology. Please click here for more details.
