Running

As a member of Team In Training, I ran two marathons, and raised money for the Leukemia and Lymphoma Society. More information

Since October 1, 2001, I've been working at Space and Naval Warfare Systems Center San Diego. I'm in the RF Communications Systems Division of the Communication and Information Systems Department. I was hired through the New Professionals Program. Contact me for more information.

Math

Published papers

Many varieties of lattices with nonsurjective epimorphisms, Algebra Universalis, 55 (2006) 67-84.
Small sublattices with large dominions, Algebra Universalis, 55 (2006) 85-92.

I finished my Ph.D. in May 2001, in the Department of Mathematics at UC Berkeley. My adviser was George Bergman. My research was in epimorphisms and dominions in varieties of lattices. You can get my main results in PDF, in Postscript, or in DVI.

My dissertation is available in PDF , Postscript , and DVI .

I received my B.A. in Mathematics in June 1995, from UC San Diego.

I have written a large Java program to do computations with modular lattices. You can view the code and documentation here .

Here's my favorite lattice theory question: Is there a nontrivial lattice that is not generated by the union of two proper sublattices? Please email me if you know the answer. Here's what I know about this question.

I'm a regular contributor to the On-Line Encyclopedia of Integer Sequences. I consider this to be my most significant contribution. Recently I've been interested in the arithmetic progressions of numbers with the same prime signature.

Hobbies

I enjoy ballroom dancing. On Friday or Saturday nights you might find me at Cheek 2 Cheek, Champion Ballroom Academy, or Starlight Dance Studio. Sometimes I dance in Orange County. I haven't been dancing much lately.

I like parties where I can do a dozen different dances in one night, such as waltz, foxtrot, tango, Viennese waltz, cha-cha, rumba, samba, salsa, East Coast swing, West Coast swing, hustle, and nightclub 2-step. So I don't often go to swing parties or salsa clubs.

I also play piano, read books, and listen to a lot of music.
