Sin Urban is Associate Professor of Molecular Biology and Genetics at the Johns Hopkins University School of Medicine (USA) and the Howard Hughes Medical Institute (HHMI). He received his B.Sc. in Honours Genetics at the University of Alberta (Canada), where he studied viral replication. He obtained a Ph.D. in 2002 from the University of Cambridge (UK), conducting research at the MRC Laboratory of Molecular Biology, where he discovered that the Drosophila signaling factor rhomboid is an intramembrane protease. Dr. Urban continued his work in Cambridge as a JB & Millicent Kaye Prize Fellow in Cancer Studies, and then in 2004 started his independent lab as a Harvard Fellow at Harvard Medical School. Dr. Urban was recruited to Johns Hopkins in 2006, where his research now encompasses investigating the pathogenic functions and biophysical mechanisms of intramembrane proteases. Dr. Urban is also Director of Admissions of the Biochemistry, Cellular and Molecular Biology Ph.D. program at Johns Hopkins, and serves on the Editorial Boards of the Journal of Biological Chemistry and BBA Biomembranes. Dr. Urban has received awards for his work, including: the Genetics Society of America Sandler Award for Outstanding Ph.D. Dissertation, Oxford University's Rolleston and MRC's Max Perutz Prizes for Original Research, HRH the Princess of Wales' Canada Scholarship for AIDS Research, the Cambridge Gedge Prize for Outstanding Observations in Physiology, and career awards from the Burroughs-Wellcome Fund, the David & Lucile Packard Foundation, and the Howard Hughes Medical Institute.
