Premios y Distinciones

  •   Rodger Doxsey Travel Prize Winner

    American Astronomical Society (AAS)

    Estados Unidos, 2012

    The Rodger Doxsey Travel Prize provides graduate students within one year of receiving or receipt of their PhD a monetary prize to enable the oral presentation of their dissertation research at a winter AAS meeting.

  •   ASNY Graduate Student Prize Paper Winner

    Astronomical Society of New York (ASNY)

    Chile, 2011

    This is awarded each year for the best research paper on some aspect of research in astronomy submitted to the Prize Committee. The submitted materials are quite often derived from the dissertation of the student, but they can be from any original research. In the case of work done in collaboration with a faculty member, that faculty member should write a letter to the Committee in which their participation and that of the student are clearly detailed.The Prize winner receives a check for $500 when the Prize lecture is delivered.
