Research Interests

I am part of the Galactic Archaeology group at the Department of Physics. My research focuses in the chemical evolution of the Universe, revealed by spectroscopic studies of metal-poor stars. These stars, due to their low mass (and long lives) are excellent probes of the conditions in the early Universe by the time of their formation. I am specially interested in measuring abundances for elements such as: lithium, carbon, nitrogen, oxygen, and neutron-capture (strontium, barium, europium, lead, among others). These abundances are used to constrain theoretical models of both stellar and galactic chemical evolution.

My work ranges from large database manipulation (to select suitable targets for spectroscopic follow-up), statistical methods, preparing and executing observations, reducing and processing data, to high-resolution spectral synthesis of absorption features in stellar spectra. 

I have experience with proposals / observations / data processing in telescopes such as: Hubble Space Telescope, Gemini North, Gemini South, Subaru, ESO/VLT, Magellan, CFHT, ESO/NTT, SOAR, KPNO/Mayall, McDonald 82in, among others.  Our group is responsible for the spectroscopic follow-up of thousands of metal-poor star candidates over the last decade using these facilities, and we have many ongoing efforts to increase these numbers even further.
