Areas of research:
I'm doing my first postdoc at Perimeter Institute with a joint appointment as a CITA National Fellow (U of Guelph). I completed my PhD as a CONICET fellow in Argentina at the Argentine Institute of Radioastronomy, La Plata. I'm currently working on predicting the electromagnetic emission of binary neutron star mergers and supermassive black hole binaries, observing radio pulsars, and solving theoretical problems in General Relativity.
During my undergrad and Ph.D. I worked as teaching assistant in a variety of courses, from Physics I to General Relativity and Mathematical Methods in Physics. I have also co-advised a master's thesis in observational astronomy.
I'm interested in gravitation, compact objects, high-energy astrophysics, and foundations of science.
