I am a postdoc scholar in the Institute for Gravitation and the Cosmos, here, at the Pennsylvania State University. My research focuses on the dynamical evolution of astrophysical compact objects in events where black holes and neutron stars coalesce. In these cataclysmic events, the governing equations of gravity and matter are in a highly nonlinear regime. Therefore, to solve the equations and understand the underlying physics of these phenomena, numerical methods are required. As such, I devise and develop numerical relativity infrastructures, for CPU and GPU high-performance clusters, to create initial data as well as dynamical evolutions of these gravitational systems. For numerical relativity projects and problems, I am looking forward to being reached at akr6170 at psu.

About our wordmark
Monica Rincon Ramirez

The IGC wordmark was created by Monica Rincon Ramirez while she was a graduate student at the Institute. Monica enjoys drawing new connections between fundamental theory and observations. Her graduate work included general relativity, loop quantum gravity, and quantum fields in cosmological backgrounds; her thesis focused on effective quantum corrections to gravitational phenomena from spinfoams and applications to cosmology. She received her PhD in 2024.

The wordmark symbolizes the scope of research at the IGC. The base represents quantum gravity, evoking the quantum geometrical picture from spinfoams and loop quantum gravity — approaches studied at the Center for Fundamental Theory. The middle shows galaxies embedded in a smooth surface characteristic of spacetime in general relativity and the larger physical scales studied at the Center for Theoretical and Observational Cosmology. The top curves to an extreme representing a supermassive black hole accompanied by an energetic jet, with a binary black hole pair nearby — the high-energy phenomena studied at the Center for Multimessenger Astrophysics.
