Jatin M. Vyas received his PhD in Immunology working in the laboratory of Robert Rich at the Baylor College of Medicine. After completing his MD at Baylor, he performed his internship and medical residency at the Massachusetts General Hospital. He completed his Infectious Disease Fellowship at the MGH/BWH. He did his post-doctoral work in the laboratory of Hidde Ploegh.

The Vyas laboratory at the MGH focuses on the host response to fungal pathogens.
Dendritic cells (DCs) represent the bridge between innate and adaptive immunity. This cell type possesses the unique capacity to activate naïve T cells. In order to carry out this function, DCs capture microorganisms and place them in membrane-delimited compartments termed phagosomes. We use fungal pathogens of clinical importance including Cryptococcus neoformans, Aspergillus fumigatus and Candida albicans as the model pathogens to study phagosome formation and maturation. Using live cell imaging with spinning disk confocal microscopy, we visualize primary DCs and its responses to exposure to fungi in real time using fluorescently-tagged proteins of the endocytic pathway and the antigen processing and presentation machinery. We examine the role of Dectin-1, LC-3 (member of the autophagy family of proteins) Toll-like receptors and members of the tetraspanin family and their effects on phagosomal maturation.
