I received my Ph.D. and Master of Science degrees in Computer Science from Cornell University in August of 2006 and 2002, respectively. Prior to that, I received my Bachelor of Science degree from Carnegie Mellon University in the dual majors of Computer Science and Mathematical Sciences in May of 1998. The Mathematics Genealogy Project traces my mathematical ancestry (by Ph.D. advisor) as shown below.

Notes for Students:

It is worthwhile to investigate how the scientific philosophies and ideas of your field have propagated down to your professors from their teachers, and eventually to you. Here some anecdotes about some of the folks above that you might find interesting.

E. H. Moore did some of the pioneering work on mathematical axiom systems that eventually led to what we now call computability. His student, Oswald Veblen was part of the team that built the first digital computer—the ENIAC. Veblen's student, Alonzo Church became one of the founding fathers of functional programming. He invented the lambda calculus and co-posited the Church-Turing thesis, which many identify as the birth of computer science as a discipline. Church's student, Stephen Kleene went on to develop recursion theory, regular expressions, and many other foundations of computability theory.

Kleene's student, Bob Constable, is currently a professor at Cornell and graduated the very first student from the computer science department there. His research involves automated, logic-based programming and theorem-proving. Bob Harper, Dr. Constable's student, is a professor at Carnegie Mellon and a major figure in type theory research. He made significant contributions to the development of the Standard ML functional programming language. Finally, his student and my Ph.D. advisor, Greg Morrisett, is the former CS Chair at Harvard and now the CIS Dean at Cornell. His research is some of the earliest to apply type theory and compiler design to computer security, giving rise to the field of language-based security, which is my primary area of research.

My other Ph.D. advisor, Fred Schneider has played a pivotal role in carving out a science of computer security, making seminal contributions toward the formalization of fault-tolerance in distributed systems, artificial software diversity for security and reliability, in-lined reference monitors, and the state machine approach to replication management. His grand-advisor, Wan-Hee Kim, is known as the "father of the Korean Electronics Industry". Kim's advisor ancestry traces to Vannevar Bush, who (among many other accomplishments) founded Raytheon Company, administrated the Manhattan Project (giving birth to the atomic bomb), and launched the U.S. National Science Foundation. His advisor, Arthur E. Kennelly was apprenticed by Thomas Edison at his famous West Orange Laboratory.
