Johanna is an astronomer who finds and characterizes planets around other stars to better understand how unique Earth is in the Galaxy. She does this mostly using large ground-based telescopes, and observing in the high desert of Chile is her favorite part of her job. She also works to build supportive, diverse, and interdisciplinary scientific collaborations. Johanna has a B.S. in Physics from American University and a Ph.D. in Astronomy from the University of Arizona, and now works in Washington, D.C.
