Alex Preciado

I am a data scientist working at HelloFresh Canada and a former postdoctoral researcher and astrophysicist of the Event Horizon Telescope (EHT) Collaboration. I was part of the international team of 200+ researchers that captured the first-ever image of a black hole.

Previously, I was a postdoctoral researcher at the Perimeter Institute for Theoretical Physics, where I developed software and models for major international scientific collaborations to analyze astrophysical data. I'm a core developer of THEMIS, a Bayesian parameter estimation and model comparison framework used by the Event Horizon Telescope to analyze the astrophysical data that has resulted in the first images of the cores of the galaxies M87 and 3C 279.
