John Srouji



John wisely traded the sunny skies of Northern California for the “motivating” weather of the Boston area to study what he realized he was interested in his last year as an undergraduate: evolution. At the University of California, Berkeley, he performed research in the fields of enzymology and computational biology with the broad goal of understanding the structural determinants of enzyme function and how the evolution of these regions confers novel activity. When he joined the lab as an MCO graduate student via the MCB Department, John sought to combine biochemical and structural lines of investigation with genetics and developmental biology to study the molecular and evolutionary processes that underlie germ cell formation in divergent organisms. He was a joint PhD candidate with Prof. Andres Leschziner.

John was supported by a National Science Foundation Graduate Research Fellowship during his PhD candidacy.

John successfully defended his PhD thesis on April 16, 2015. Congratulations John! See pictures of the champagne toast here.
