I am an assistant professor at the Department of Physics and Astronomy of the University of Alabama. My research interests lie in high-energy neutrino, gamma-ray, and cosmic-ray astrophysics, and the development of new astroparticle physics instrumentation.
My research group is involved in the IceCube, VERITAS, CTA and SWGO Collaborations and also work with data from a number of ground- and space-based telescopes (in particular Fermi, Swift, and NuSTAR).
Ph.D. (Physics) - University of Wisconsin-Madison (2013)
M.A. (Physics) - University of Wisconsin-Madison (2011)
B.S. (Engineering) - Universidad Tecnológica Nacional, Argentina (2009)
Postdoc positions available
Two postdoctoral positions on neutrino and gamma-ray astrophysics with IceCube and VERITAS/CTA.
Details coming soon, please contact me with questions.
