Short Biography

I grew up in the Northern Suburbs of Chicago, and graduated from Stevenson High School in 2000. In 2004 I received my B.S. degree from the University of Iowa (in Iowa City). Then in 2010 I received my Ph.D. from the University of Wisconsin - Madison. Now I am a postdoctoral fellow at Northwestern University and the Adler Planetarium.

I went into college intending to pursue a double major in Physics and Studio Art (i.e., painting, drawing, etc.). I had always been interested in Astronomy, and after taking my first astronomy class at the UI, I was hooked, and declared Astronomy as another major. By the end my second year, I decided to move Studio Art to a minor (art history classes were not enjoyable), and focus more attention on astronomy. I started a research project with Steve Spangler, simulating observations using a VLA antenna made near the Sun to study the Solar wind. After my junior year, I spent a summer at the National Radio Astronomy Observatory in Green Bank, West Virginia as an NSF REU student. I worked with Tony Minter to model the Galactic magnetic field. At the start of my senior year, I realized that I only needed a few more classes to get a Mathematics major as well. In 2004 I received my B.S. degree with majors in Physics, Astronomy and Mathematics (and honors in Physics and Astronomy).

I went straight into graduate school at the University of Wisconsin - Madison. During my first semester I was a Teaching Assistant for the Astro 104 "Exploration of the Solar System" course. The next semester, I began working with Bob Mathieu, and I have continued collaborating with Bob ever since. After receiving my Masters degree in 2006, I began my thesis work studying the old (7 Gyr) open cluster NGC 188. In my 5th year at the UW, I co-taught the Astronomy 113 "Hands on the Universe " lab course. During my 6 years at the UW, I learned a great detail about being a scientist, performing astronomy research, teaching and mentoring. In August of 2010, I completed my doctoral thesis and received my Ph.D.

From 2010 to 2013 I was the Lindheimer Postdoctoral Fellow at Northwestern University. Through mid-2017, I was an NSF AAPF fellow. I am currently jointly appointed at Northwestern and the Adler Planetarium. I am pursuing a number of exciting research projects. And I am also enjoying my time back in the Northern suburbs of Chicago.
