Edo Berger is the John L. Loeb Associate Professor of the Natural Sciences and, as of July, Acting Director of Undergraduate Studies for the department.  He is pictured above with graduate student, Wen-fai Fong, in front of a model of colliding neutron stars that they assert are responsible for the creation of such heavy metals as gold in the universe.  His research group (view students and postdocs) is focused on the study of gamma-ray bursts, optical transients (mainly from the Pan-STARRS project), and magnetic fields in low-mass stars and brown dwarfs, using observations across the electromagnetic spectrum, from radio to γ-rays. Prof Berger was recently selected as the recipient of the 2013 Fannie Cox Prize for Excellence in Science Teaching awarded annually by Harvard's Faculty of Arts & Sciences.
