Following his work with the National Space Society during his senior year at the university, Mr. Groswald decided to pursue a career in space policy, educating the public on space issues, and formulating policy.
VICTORIA SWISHER joined the SSB in 2006 as a research associate. Her most recent research focused on laboratory astrophysics and involved studying the x rays of plasma, culminating in a senior thesis entitled “Modeling UV and X-ray Spectra from the Swarthmore Spheromak Experiment.” She has presented results of her research at the 2005 and 2006 AAS meetings and at various Keck Northeast Astronomy Consortium undergraduate research conferences. She received a B.A. in astronomy from Swarthmore College. Ms. Swisher left the SSB in August 2009 to pursue a master’s degree in international policy studies, with a focus on nonproliferation, at the Monterey Institute of International Studies.
CATHERINE A. GRUBER, editor, joined the SSB as a senior program assistant in 1995. Ms. Gruber first came to the NRC in 1988 as a senior secretary for the Computer Science and Telecommunications Board and also worked as an outreach assistant for the National Science Resources Center. She was a research assistant (chemist) in the National Institute of Mental Health’s Laboratory of Cell Biology for 2 years. She has a B.A. in natural science from St. Mary’s College of Maryland.
ANDREA M. REBHOLZ joined the ASEB as a program associate in January 2009. She began her career at the National Academies in October 2005 as a senior program assistant for the Institute of Medicine’s Forum on Drug Discovery, Development, and Translation. Prior to the Academies, she worked in the communications department
of a D.C.-based think tank. Ms. Rebholz graduated from George Mason University’s New Century College in 2003 with a B.A. in integrative studies−event management and has more than 7 years of experience in event planning.
RODNEY N. HOWARD joined the SSB as a senior project assistant in 2002. Before he joined SSB, most of his vocational life was spent in the health profession—as a pharmacy technologist at Doctor’s Hospital in Lanham, Maryland, and as an interim center administrator at the Concentra Medical Center in Jessup, Maryland. During that time, he participated in a number of Quality Circle Initiatives that were designed to improve relations between management and staff. Mr. Howard obtained his B.A. in communications from the University of Baltimore County in 1983. He plans to begin coursework next year for his master’s degree in business administration.
