Mark grew up in Texas, and then traveled around the country for his education. After going to college at Cornell University, he returned to Texas for the MD/PhD Program at Baylor College of Medicine. During his PhD, he studied the mechanisms underlying neurotransmitter release in Drosophila with Hugo Bellen. He then set off for sunny Los Angeles to do his residency in Neurology. His next move was to Philadelphia, where he completed a sleep medicine fellowship at the University of Pennsylvania. While at Penn, he performed his postdoctoral research with Amita Sehgal, studying genetic mechanisms underlying sleep in Drosophila. He finally headed down to Baltimore to Johns Hopkins to set up his own lab there. Mark is also a board-certified neurologist and sleep medicine specialist, and he sees patients in both sleep medicine clinic and on the neurology wards.
