Tobias, a native of Switzerland, moved to the US in 1990 to attend college at Duke University. After undergraduate research stints at the Biocenter in Basel (with Jeff Schatz) and at the Whitehead institute (with Harvey Lodish), Tobias moved to New York in 1993 to enroll in the Tri-Institutional MD-PhD Program. As graduate student, Tobias studied the mechanisms of SNARE complex formation and disassembly in Jim Rothman’s lab and explored the potential of genetically encoded reporters of biological function under Gero Miesenböck. Tobias went on to train in internal medicine and infectious diseases and joined Eric Pamer’s lab for post-doctoral studies in fungal pathogenesis and immunology. In 2009, Tobias started his own laboratory-based research program at Fred Hutchinson Cancer Research Center. He returned to Memorial Sloan Kettering in 2013 where he is now the Chief of the Infectious Disease Service. Outside the lab, Tobias loves to explore New York on foot and on the bicycle; his current favorite show is Billions.
