Difusión y Transferencia


I believe that it is a social responsibility of researchers to promote scientific culture through direct communication with people, public talks and various outreach activities. Our goal should be to transmit ideas that allow society to assess the importance of science as a way of understanding the nature and our environment, and as a booster of technological and social development. In the particular case of astronomy, it is especially important to contribute to the dissemination of the scientific advances made in Chile, as well as to help to
strengthen the self-perception, the nation-brand of Chile, as one of the privileged windows in the world to observe the universe.
In the last three years I have maintained an intense outreach activity in the Millennium Institute of Astrophysics as part of the creative committee behind the development of several outreach products (https://www.astrofisicamas.cl/extension-mas/). In the same vein, I have maintained periodic appearances in press and television, as well as in public talks in the context of massive activities for the general public. I was the scientific advisor of the television series "El Perrito Galáctico".


Premios y Distinciones

  •   Beca Padre Hurtado

    PONTIFICIA UNIVERSIDAD CATOLICA DE CHILE

    Chile, 2005

    It consists of a scholarship to study free of charges at Pontificia Universidad Católica de Chile (long before the enactment of the "Ley de gratuidad"). This award was given to ~ 100 students with the best scores in the university access process to PUC, and according to their socioeconomic status.

  •   Premio Inglés UC

    PONTIFICIA UNIVERSIDAD CATOLICA DE CHILE

    Chile, 2009

    In the link above, please go to page 36. Other scattered news can still be found, but they are old and scarce. This prize is awarded annually to the student with the best academic performance in the university's English courses (in recent years has been awarded to more than one student). The prize consisted of a one-month stay in an english school in England (Canterbury).
