Research team

It has been my pleasure to work with many talented people over my career, and below is some information about them. Currently, I am a member of the Institute for Gravitational Research in Glasgow, and work closely with the CIERA Group of Vicky Kalogera. If you might be interested in joining as a postdoctoral fellow, please get in touch!

Current group


Chase Kimball (Northwestern, 2018–Present)
Chase is researching how to use our gravitational wave observations to understand the population of compact binaries. He is especially interested in hierarchical mergers, where the remnant of one merging binary goes on to merge again.

Eve worked on uncovering the properties of black holes using gravitational wave data and the properties of neutron stars with electromagnetic data. She has been busy inferring the properties of LIGO–Virgo sources (she was one of the leads for GW170608), and she explored what we can do observations of kilonovae. After her PhD, Eve became a Postdoc at Los Alamos National Lab.
