Jeff is a physics professor, but his research is in computational biophysics. He’s very much a cross-discipline academic, working fluidly at the conjunction of a few different fields. He’s working on using supercomputers to track individual molecules and contribute to the understanding of genetics. As a theoretical physicist, he doesn’t do experiments in a physics lab; his work is done at an average-looking desk on an average-looking computer, which is connected to a monster computer in a nearby server room. Not much to see, really. We needed a photo to accompany an article about him getting a five-year renewal of his funding from the National Institute of General Medical Sciences.
