My Mathematical Interests

I am interested in analytic number theory. Some of my recent papers involve sieve methods, Sidon sequences, distribution of values of the Euler-phi function, and divisors of factorials. Some of my recent papers are available for download in pdf and dvi formats.

I have Erdös number 1, but so do over 500 other people. My one paper with Erdös is on divisors of factorials.

Separated at Birth?

I spent three years working at the National Science Foundation in Arlington, Virginia. People would occasionally mistake me for Representative Peter DeFazio, D-Oregon. Compare for yourself.



Pictures from France

In July 2004, Mary and I went on barge cruise in Burgundy. Here are some pictures from the trip.
