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.

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.

PhD Candidate
Qinyuan Zheng’s research has two branches. On the formal side, he is interested in using effective field theory to understand the scattering processes involving gravitational bound systems, which could reveal new insights including potential connections between scattering amplitudes of gravity and of gauge theories. He also investigates how both stochastic and continuous GWs can have measurable effects on binary systems with pulsars, which he hopes can be used as another alternative GW detection scheme.

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 |
