Research Overview

Advanced molecular biology and bioinformatics are combined with traditional microbiology to reveal connections between infectious agents and diseases of unknown etiology or emerging epidemiology. Lab emphasis is on detection and characterization of potential pathogens and investigating host microbial interactions to reveal underlying mechanisms of disease as well as targets for diagnosis or intervention.  Broad areas of study include microbial, in particular viral, discovery in the context of clinical disease, at the human animal/vector interface, and in the contexts of immunocompromise or cancer.


Michael McIntosh began his infectious disease career in herpes virology at Thomas Jefferson University.  He later earned a Ph.D. in Molecular Biology and Biotechnology in 1995 at the Medical College of Pennsylvania & Hahnemann University (now Drexel Medical College) where he investigated the unique biology of mitochondria in the malaria parasite.  He did postdoctoral fellowships in human polyomavirus JC research at Thomas Jefferson University and in malaria research at Drexel Medical College before joining the faculty at Yale University to investigate mechanisms of endocytosis by the malaria parasite.  In 2004, he joined the USDA National Veterinary Services Laboratories’ Foreign Animal Disease Diagnostic Laboratory (FADDL) on Plum Island where he served as a member of FADDL’s emergency Diagnostic Team, Head of the Proficiency and Validation Services Section, Head of Bioforensics, and most recently as Science Liaison.

Much of Dr. McIntosh’s scientific career has focused on diagnosis of emerging and foreign animal diseases, development and validation of new diagnostic tests, and development and use of cutting-edge molecular approaches to infectious disease diagnostics. His laboratory’s development of advanced molecular methods for virus detection, including panviral microarrays and next-generation sequencing have led to impactful examples of disease detection and response on national and international scales, most notably, the discovery of domestic swine as a host for Ebola.
