John MacMicking, PhD

Associate Professor of Microbial Pathogenesis and of Immunobiology; Member, Yale Systems Biology Institute; Investigator, Howard Hughes Medical Institute



John MacMicking is a Howard Hughes Medical Institute (HHMI) Investigator. He trained in synthetic organic chemistry at the Australian National University (B.Sc, 1st Class Honors) where he conducted thesis work in the Department of Immunology & Cell Biology formerly headed by 1996 Nobel Laureate, Peter Doherty, at the John Curtin School of Medical Research.

He then came to the U.S. to pursue Ph.D studies with Carl Nathan in the Immunology program at Cornell University-Sloan-Kettering Institute in New York City before being selected as an HHMI Life Science Research Foundation Fellow at The Rockefeller University to conduct studies with John McKinney.

His doctoral dissertation described the first knockout of an innate immune gene in mammals - inducible nitric oxide synthase (iNOS) - genetically engineered between 1992-1995. It served as an early paradigm for cell-autonomous immunity to bacterial, viral and protozoan infections. At Rockefeller University he computationally identified, physically mapped and began functionally characterizing a complete IFN-inducible GTPase superfamily in humans and mice as a new defense network operating against all pathogen classes. For these discoveries he has been named a Edward Mallinckrodt Jr Foundation Fellow (2004), Searle Scholar (2005), Cancer Research Institute Investigator (2006), Burroughs-Wellcome Fund Investigator (2008), CCFA Senior Research Awardee (2010), AAF Scholar (2014) and Kenneth Rainin Foundation Innovator (2014).

Dr. MacMicking was promoted to Associate Professor in 2010 and received Tenure in 2014. He was chosen as an HHMI Investigator in 2015 before moving to the Yale Systems Biology Institute in 2017.
