El profesor Castañeda es una de las figuras más relevantes en Física, tanto a nivel regional como nacional. Es un honor para la facultad de Ciencias de la Universidad Nacional de Colombia, sede Medellín tenerlo entre la planta de sus docentes. Es un profesor que se ha distinguido como investigador de primera línea en óptica donde ha integrado un grupo de colaboradores en esta área, siendo reconocido como uno de los grupos de investigación más consolidados a nivel nacional, lo cual se refleja en el gran número de publicaciones tanto nacionales como internacionales. También se destaca su espíritu colaborador en labores de índole administrativa tanto en la Facultad de Ciencias como en la Sede, donde ha desempeñado cargos como Director de la DIME. Además, es notable su personalidad polifacética ya que ha incursionado en la escritura de relatos cortos. Como escritor, ha logrado publicar un libro de cuentos.

Professor Castañeda is one of the most important persons in the world of physics at local and national level. It is an honor for the College of Sciences at the National University of Colombia at Medellin having him as a member of its faculty. Professor Castañeda has distinguished a top researcher in optics, area in which he has established one of the best research groups in this topic which is re ected by the number of publications in international and national journals by this group. It is also remarkable the cooperation in the administrative work that professor Castañeda is willing to do. He has been chairman of the research office DIME at this university. We also notice that among the personal interests of professor Castañeda is in short story writings. As a writer he has published a book of his short stories.
