Professional development activities involve field trips, colloquia and panel discussions. On most Wednesdays we take a field trip to or have a vist from a nearby federal agency or business that employs mathematicians. Past destinations have included the National Institute of Standards and Technology (NIST), the National Security Agency (NSA), Booz Allen Hamilton, GEICO Insurance and Northrup Grumman. We also have colloquia given by established figures from academia, government and industry to offer personal insights as well as panel discussions to provide advice on preparing for and succeeding in graduate school, and advice on how to obtain financial support.
