Aran Nebula STEM Leadership Cohort #1

Lia Medeiros

Lia is co-lead of the EHT Gravitational Physics Working Group, a member of the EHT’s Junior Scientist Council, and an NSF Astronomy and Astrophysics Postdoctoral Fellow, working at the Institute for Advanced Study.

She co-leads one of six collaboration papers published in 2022 that presented groundbreaking results about the black hole in the center of our galaxy, Sgr A*.

Her current focus includes developing simulations of accreting black holes, and black holes that differ from the predictions of Einstein's theory of General Relativity, and then comparing these simulations to EHT data. She also used a large library of high-fidelity simulations as a training set for a new algorithm she developed for image reconstruction with EHT data.

Her algorithm achieves unprecedented resolution and accuracy. By modeling hypothetical black holes that challenge our understanding of gravity and comparing these exotic structures to EHT observations, she is able to test General Relativity.
