I started teaching at OSU in September of 2006. I spent the 2007-2008 school year visiting at Cornell (where my wife is studying for a PhD in Musicology), while on a leave of absence.

Students
Denny Jackson
Denny has been working on developing a classical density functional describing water in its liquid and vapor states. This functional is based on the "Fundamental-Measure Theory" density functional for describing the hard-sphere fluid. For a bit more information, see slides from the talk he presented at the APS NW meeting in May 2008.Jess Gallagher

Jason Dagit
Jason got a Masters degree in Computer Science, working on the patch
theory of darcs and ensuring its proper
use via type witnesses.
