Galaxy Dynamics Lab - studying central black hole seeds and their
co-evolution with host galaxies across cosmic time.
USAC Astrophysics Research Group - investigating the formation of central black holes
and their co-evolution with host galaxies using world-class observatories (JWST, HST, ALMA, VLT, and ELT).

Core Themes of
My Research
Black Hole Formation and Growth
Where do the seeds of today’s massive black holes come from, and how do they grow into the giants we observe? I use precise dynamical masses of nearby black holes as fossil records of their formation and growth history.

Massive Black Holes Across the Mass Spectrum
Measuring black hole masses continuously from the intermediate-mass regime in dwarf galaxies and star clusters up to the supermassive black holes of giant ellipticals, with a single, consistent dynamical approach.

Black Hole and Galaxy Coevolution
Black holes and their host galaxies appear to grow together. I test how tightly that coupling holds across morphology, mass and environment using dynamical masses paired with detailed host measurements.

Stellar and Gas Kinematics and Galaxy Dynamics
Kinematics is the most direct probe of mass. I model stellar and cold-gas motions in galactic nuclei to weigh central black holes and to characterise the dynamical structure of their hosts.

Computational Astrophysics, Simulations, and Modelling
Building simulation and modelling tools that predict what future instruments can actually measure, and turning raw datacubes into physical parameters through forward modelling.

We use numerous telescopes at different wavelengths to study photometry and kinematics of objects. Most are state-of-the-art, including ALMA, HST, VLT, JWST, and we look forward to the [...]
