My PI worked for two (2) Nobel laureates

I already knew Jeff got his Ph.D. at MIT, but what I didn't know is that both of his mentors were Nobel laureates: H. Robert Horvitz and Eric F. Wieschaus. Wow. I had seen publications with Jeff and Dr. Wieschaus's names on them, but I never knew who that guy was. Now I do, and now I am fearful.
