Dominic Chang
I am currently a PhD candidate in physics at Harvard University working under Michael Johnson with the local Event Horizon Telescope (EHT) group. I currently research black hole phenomenology. Some topics and techniques I routinely use include strong field gravitational lensing, the phenomenology of exotic black hole space times, Newman-Penrose formalism and Bayesian inference.

Krang.jl: Physics inference from images of black holes
Dominic Chang
The images of the shadows of M87 and SgrA* have produced an increased interest in the study of electromagnetic signatures around black holes. These images probe the near horizon region of black holes with unprecedented fidelity. I will present an gpu compatible raytracing code that can be used to model the emission from accretion flows around Kerr black holes.
