Did you know that bacteria such as Escherichia coli and Salmonella swim using a motor called the flagellum? The flagellum is a motor 20 nm in diameter and about 10 μm long, assembled from more than 20,000 protein molecules, and it spins at over 10,000 revolutions per minute.

I study how this nanomachine found in living organisms works, through structural analysis at atomic resolution.
