David Evensky holds a Ph.D. in Chemical Physics from the University of Illinois, a M.S. in Chemistry, and a B.S. in Chemistry and Computer Science from the University of Iowa. He is currently a Principle Member of Technical Staff at Sandia National Laboratories at the Livermore California site. He has been working on clusters and hacking with Linux since 1993 and is currently the PI for CPlant at the California site. In a previous life he did science and liked it, did scalable middle-ware and liked that, and did security and thought that it was OK if he wanted to be paranoid all the time. He is much better now, but writes in the third person from time to time.
