Kempner.net is the personal web site of Joshua Kempner. I used to work in astrophysics before leaving the field for VisEn Medical in the Boston area, where I'm now Principal Scientist. VisEn was acquired by PerkinElmer in July 2010.

These days, I put most of my non-work time into being a dad. I also spend some of my free time playing, coaching and refereeing soccer.
