Bio

Kathryn Johnston joined the Center for Computational Astrophysics as a Group Leader for the Dynamics Group in 2019. Kathryn got her PhD. and M.A. in Astronomy from UC Santa Cruz and her B.A. in Mathematics from Cambridge University. Kathryn was a postdoctoral member at IAS, as well as an Associate Professor at Wesleyan. She has been teaching at Columbia University since 2006, and was Chair of the Astronomy Department from 2014 to 2017. As part of a dynamic and growing group, Kathryn will develop algorithms and codes for computational astrophysics, analyze large astronomy data sets.
