After graduating from Cornell University with a BA in Astronomy, Professor Kratzer moved to Philadelphia to pursue her graduate work, which focused on the radio properties of quasars, at Drexel University. After earning her PhD in 2014, she spent a year and a half as a 3/4-time instructor at Rowan University teaching undergraduate physics and advising the Astronomy Club. In the Winter of 2016, she returned to Drexel’s physics department as an Assistant Teaching Professor. In addition to her teaching responsibilities, she is particularly interested in astronomy outreach as well as improving the learning outcomes in all undergraduate courses (particularly non-major courses).

When she’s not teaching, you can probably find Professor Kratzer riding her bike in and around Philadelphia, enjoying nature with her daughter, walking her dog, cooking/eating, cheering on the Eagles/Phillies, or listening to music.
