I obtained my BSc degree in Physics from Universidad Nacional de Colombia in 1998. In 2002 I moved to the USA to pursue graduate studies and received my PhD in theoretical nuclear physics in 2008 from Indiana University.
After graduating from my PhD I was a visiting scientist in the Nuclear Theory Group at Los Alamos National Laboratory (summer of 2008). I was then a Research Associate at North Carolina State University (from 2008 to 2010), a Postdoctoral fellow in 2011 at the Institute for Nuclear Theory at the University of Washington. I moved to Germany in 2012 to join the ExtreMe Matter Institute and the Institute of Nuclear Physics of the Darmstadt Technical University as a Postdoctoral fellow. I held a Research Associate position at the Joint Institute for Nuclear Astrophysics at Michigan State University during the summer of 2013, and I have been at the University of Guelph since 2013.
I have been a lecturer at several institutions, including: Universidad Nacional de Colombia, Universidad de Los Andes, Indiana University, the University of Washington, and the University of Guelph. I have also been employed at the International Center of Physics at the Universidad Nacional de Colombia, and developed Tsunami simulations at the Pacific Center for Pollution Control in Tumaco, Colombia.

My field of research is theoretical nuclear astrophysics. I am interested in the connection between nuclear forces and several phenomena observed in the Universe, such as the synthesis of heavy elements, the neutrino emission in core-collapse supernova and neutron star mergers, and bursts in accreting neutron stars. These phenomena occur under extreme temperature and density conditions, making these astrophysical environments excellent extraterrestrial labs to test our theories of the interaction between neutrons and protons. Additionally, the same sites involve large masses making gravity play a fundamental role. My research aims to expand our understanding of the interplay between neutrinos, nuclear interactions, and gravity in astrophysics.
