Erika Nesvold is a Carnegie Postdoctoral Fellow in the Department of Terrestrial Magnetism at the Carnegie Institution of Washington. She grew up in a military family and has lived on numerous army bases in the U.S. and Europe. After completing a B.S. in mathematics at the University of Maryland, Baltimore County, she decided at the last possible moment to give astronomy a try, and moved all the way across the UMBC campus to complete an M.S. and Ph.D in the physics department. She did most of her graduate research at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, working with Marc Kuchner on developing a circumstellar debris disk model that included collisions between planetesimals. Now at Carnegie, Erika is continuing to develop and apply her debris disk models in collaboration with astronomers from Los Angeles to Boston. Erika currently lives just over the river in Alexandria, Virginia, and works every Sunday as a volunteer firefighter and EMT at the Odenton Volunteer Fire Company in Maryland, where she has been a member for nearly thirteen years. She also tweets (inconsistently) @erikanesvold and occasionally blogs for www.astrobites.org, a graduate student-run arXiv reader’s digest, and www.damninteresting.com, a wellspring of fascinating stories from history, science, and the history of science.
