About Me

I'm an Assistant Professor in the Physics Department at the University of Florida. My research focuses on a range of problems in supermassive black hole and galaxy evolution, including black hole formation and evolution, the role of galaxy mergers, signatures of black hole inspiral and merger, and gravitational wave sources. I specialize in numerical simulations with an emphasis on direct comparisons to observations.


My research focuses primarily on developing theoretical models and making predictions for supermassive black hole (SMBH) and galaxy evolution. My group utilizes a range of numerical techniques including gravitational, hydrodynamics, and radiative transfer simulations from galactic to cosmological scales. We also collaborate with observers to characterize new and unusual populations of active SMBHs, as well as other theorists, including the Illustris and IllustrisTNG collaborations. Our work uses institutional and national high-performance computing resources, including HiPerGator at UF. Some of our ongoing research is briefly summarized below.

  • Formation & Evolution of SMBHs and Galaxies

    Broady, I am interested in the interplay between SMBHs and their host galaxies in a range of environments and cosmic epochs. In particular, we are studying the origins and early growth of SMBHs, the role of galaxy mergers in producing the observed correlations between SMBH mass and galaxy bulges, and the demographics of the intermediate-mass BH (IMBH) population.

  • Single and Dual AGN Fueling

    I use simulations to study the mechanisms for fueling active galactic nuclei (AGN, or accreting SMBHs). My group is studying the role of galaxy mergers in triggering AGN, as well as methods for finding dual AGN and for characterizing the effects of obscuration and other selection bias in AGN observations.

  • Binary SMBH Inspiral and Merger

    Galaxy mergers are also of great interest because they lead to the formation of SMBH binaries, which are powerful sources of gravitational waves (GWs). These low-frequency gravitational waves could be detected in the coming years with pulsar timing arrays and with a space-borne laser interferometer (LISA). My group is working to constrain the uncertain timescales for binary SMBH inspiral and merger, and the resulting GW sources.

  • BH Spin Evolution & Gravitational-Wave Recoil

    When two black holes merge, asymmetry in their gravitational wave emission imparts a "recoil kick" to the merged black hole, which can in some cases eject a SMBH from its host galaxy entirely. The recoil velocity depends sensitively on the poorly constrained pre-merger SMBH spins, and my group is working on models for SMBH spin evolution in a cosmological context. I've also developed models for the observable signatures of recoiling AGN, and we are involved in ongoing campaigns to search for and confirm candidate recoils.


I'm a faculty coordinator for the Promoting Inclusive Physics & Astronomy (PIPA) group at UF.
We host a series of lunch and coffee discussions for grad students to interact with visiting women speakers, as well as occasional seminars on career paths and other topics related to life in academia

I also help organize the annual UF celebration of the International Day of Women & Girls in Science.
