Another of my research interests is Number Theory.

My Ph.D. thesis subject area was Number Theory, specifically Analytic Number Theory, or even more specifically, the Selberg Trace Formula on certain Arithmetic Groups.

• An excellent introduction to what number theory is all about is the website
  http://www.math.niu.edu/~rusin/known-math/index/11-XX.html ,
  which is part of Dave Rusin's site, The Mathematical Atlas .
  
  
• Useful (advanced) information can be found at
  
• Number Theory Web (general reference)
• Charles Li's website (reference for trace formulas)
  

Currently, Erik Tou (my "thesis sibling" -- we had the same Ph.D. adviser) and I are writing up results from our theses for publication.  The first (of a series of articles) has appeared as:

• Stemkoski, L. and E. Tou, “Explicit Constructions of Arithmetic Lattices in SL(3,R)”,
  International Journal of Mathematics and Computer Science 4 (2009), no. 1, 53-64.
