Ever wondered why your dog’s back-and-forth shaking is so effective at getting you soaked? Or how bugs, birds, and lizards can run across water—but we can’t? Or how about why cockroaches are so darn good at navigating in the dark?

Hu is an associate professor in the Schools of Mechanical Engineering and of Biological Sciences and an adjunct associate professor in the School of Physics.
