What is this place?
Kempner.net is the personal web site of Joshua Kempner. I used to work in astrophysics before leaving the field to joing VisEn Medical in the Boston area. VisEn was acquired by PerkinElmer in July 2010. I'm still with PerkinElmer, now as Senior Manager of Software Development, and continue to work on the products developed at VisEn along with the company's other in vivo imaging offerings.
