I am the Henry Ford II professor of
Computer Science,
Mathematics,
and
Applied Mathematics
at
Yale University,
a Simons Investigator and a MacArthur Fellow, the Director of Undergraduate Studies for Applied Mathematics , and the co-Director of the Yale Institute for Network Science (YINS). I co-organize the YINS Seminar and the Combinatorics and Probability Seminar. I am a member of the ACM, AMS, IEEE, SIAM, and the CT Academy of Science and Engineering. |
