I am always looking for motivated graduate students curious to understand complex intracellular molecular mechanisms relevant to our work. A strong work ethic, as demonstrated by a strong academic record, and intellectual audacity are required. If interested in becoming a member of our lab, please send me a brief letter of motivation detailing why you think you would be a good fit, together with your academic transcripts. Thanks for your interest!
