"In the more than 20 years I've been at the Universidad de Los Andes, I have always pursued the goal of bringing new experimental possibilities available to students, not only of Los Andes, but also from other universities and schools, few are willing to put their hands on science. I have particularly devoted to optics, spectroscopy and astronomy. The University´s Astronomical Observatory has arisen in my efforts to improve astronomical observations.

In a good observatory, it is possible to make several types of observations, such as: Photography, photometry (measuring the intensity of starlight) or astrometry (measuring the positions of the stars), but local weather conditions are not good at all, reason why these techniques do not give accurate results. It is more strategic for us to focus on spectroscopy (decomposition of light into colors), a technique that suffers less from environmental constraints. Since 1995, we have used more than half a dozen spectrographs to unravel the starlight, and most have been built here. And the results are still improving! "
