Dr. Marcus D. Hanwell from Kitware, Inc. is visiting the group today. Marcus is a Technical Leader in the Scientific Computing group at Kitware, where he leads the Open Chemistry project. Open Chemistry focuses on developing open-source tools to for chemistry, bioinformatics, and materials science research. He completed an experimental PhD in Physics at the University of Sheffield, a Google Summer of Code developing Avogadro and Kalzium, and a postdoctoral fellowship combining experimental and computational chemistry at the University of Pittsburgh before moving to Kitware, Inc. in late 2009. He is still a core developer of Avogadro, a very popular, open-source, 3D, cross-platform molecular visualization and editing application/library. Marcus is also a long-time friend and collaborator and we are exceedingly happy to welcome him to Buffalo.
