Andrew Casey-Clyde
Joined 2019
PhD Candidate
Andrew Casey-Clyde’s research is focused on multimessenger astrophysics with nanohertz gravitational waves. He combines quasar observations with information from the gravitational wave background to constrain supermassive black hole binary (SMBHB) populations. He is also interested in synthesizing electromagnetic and gravitational wave information to help direct targeted searches for continuous waves from individual SMBHBs. He hopes we can better understand the relationship between quasars, galaxy mergers, and SMBHBs by combining as many sources of information as possible.

Bjorn Larsen
Joined 2021
PhD student
Bjorn is currently working on creating and fitting Bayesian Gaussian Process models of noise from the interstellar and interplanetary medium for pulsars in IPTA DR3. Once IPTA DR3 is completed, Bjorn will be using these noise models to search for and characterize the gravitational wave background using the full array of pulsars.

![]() Deborah C. Good
2021-2023 Formerly: postdoctoral scholar Current Position: Faculty at University of Montana Dr. Deborah C. Good is an expert in pulsar timing. She is playing a leading role in data combination for the International Pulsar Timing Array’s third data release — IPTA DR3. She is also an expert in fast radio bursts. Deborah is a full member of NANOGrav and is a core member of the timing working group. As a doctoral student at the University of British Columbia, she was a key member of the CHIME/FRB and CHIME/Pulsar teams, including creating the first NANOGrav-CHIME/Pulsar data combination.

2020-2023 Formerly: undergraduate researcher Current Position: Graduate student at Columbia University in the Department of Astronomy Abigail works with the Gaia database to identify the binary companions of millisecond pulsars. She is also creating a data release of pulsar timing based accelerations. I hope to use these measurements of the acceleration of the Milky Way to map dark matter in the local galaxy.

![]() Siddarth Mohite
2021-2022 Formerly: graduate student researcher, joint with the Flatiron Institute Current Position: Research Scientist, LIGO Siddarth is interested in multiple aspects of gravitational-wave astronomy. For his graduate studies, he focused on uncovering the population properties of merging compact binaries observed by LIGO and their associated electro-magnetic counterparts. As a Flatiron Research Analyst, working with Chiara, the focus was on the contribution of eccentric binaries to the gravitaional-wave landscape of supermassive black hole binaries. Currently, he is a Research Associate at UWM working in the LIGO Computing group. Google Scholar Page |
![]() Nicole M. Khusid
2020-2022 Formerly: undergraduate researcher Current Position: PhD Student, Stony Brook University Nicole is interested in how strong gravitational lensing can be used as a tool to improve continuous nanohertz GW detection prospects with future PTAs, as well as a means of probing SMBHB dynamics by better resolving their EM counterparts. As a doctoral student, she is now switching focus to higher frequency GWs in the LIGO band, particularly analyzing the measurability of different quasinormal modes in ringdown signals.
