I am an Astroparticle Physicist
I am interested in understanding Dark Matter. I am from Tunisia, came to the US in 2008, obtained an undergraduate degree in physics at Boston University in 2012. I then received a PhD in particle physics at MIT in 2017, under the supervision of Prof. Jesse Thaler. I was a Sherman Fairchild Fellow at Caltech from 2017 to 2020, a UC Presidential fellow at UC Irvine, then a Fellow at Carnegie Observatories in 2020 before starting as an Assistant Professor of physics in Theoretical Astrophysics at MIT in July 2021.
Using Gaia, I modeled the kinematics of accreted stars, some of which originate from particular merger events, such as the Gaia Sausage/Gaia Enceledus.
I also discovered a new structure, called Nyx, after the Greek Goddess of the night.
I analyzed various telescope data to understand the kinematics of stars, and how it plays with Dark Matter kinematics. For example, the Fermi Telescope, and the Sloan Digital Sky Survey.
I worked on implementing methods to distinguish particular events at the Large Hadron Collider from backgrounds. Such methods were used by the experiments to set limits on hypothetical Dark Matter particles.
I used a variety of hydrodynamic simulations, FIRE, Eris, and Illustris, to correlate Dark Matter with observables.
I built a few Dark Matter models, for example Boosted Dark Matter, and studied how it can be detected in Neutrino Experiments.
