Welcome to my website!
I am interested in a variety of subjects but my main research gravitates around studying the effect of dark energy in our Universe using exploding stars called type Ia supernovae. I am also interested on machine learning applications on cosmology and other transients in the night sky. Take a look at my research page.
I belong to several surveys that search for supernovae at different distances and times in our Universe such as : SkyMapper Transient Survey, OzDES, Dark Energy Survey and SNLS. With the SkyMapper Transienty Survey we recently launched Supernova Sighting , a Zooniverse Project , where you can join us in the search for supernovae and other transients.
Currently, I am leading the SkyMapper Transient Survey. Using the SkyMapper telescope we search for "close-by" supernovae to study the expansion of the Universe and also to learn more about supernovae (types, progenitor systems, etc). I also belong to OzDES, an spectroscopic survey at the Anglo-Australian Telescope that targets mostly galaxies with supernovae detected by the Dark Energy Survey (DES). This brings me to DES where we are working to do the state-of-the-art measurement of the expansion of the Universe with these SNe Ia.
I was born in Venezuela and did my undergrad at Universidad Simón Bolívar. I then moved to France where I did the NPAC master 2 and a PhD at Irfu Cea Saclay and Université Paris Diderot. I enjoy communicating science to the general public and was selected to be a CAASTRO Astronomer in Residence. I also ejoy hiking, rock climbing, diving, sailing and playing cello.
