Biography
I’m a Post-doctoral researcher at the University of Surrey, specialising in galactic dynamics. My research focuses on the dynamics and mergers of massive black holes across different mass scales. This ranges from supermassive black holes in the centers of elliptical galaxies, relevant to pulsar timing array detections of the gravitational-wave background, to intermediate-mass black holes in dwarf galaxies, where off-center mergers present unique dynamical challenges and may be key sources for LISA. My approach combines high-resolution N-body simulations, cosmological simulations and theoretical studies of few-body dynamics.
