Dr. Sreevatsan is a Professor of Infectious Disease at the College of Veterinary Medicine, U of M. The principal focus of his laboratory is to define the molecular mechanisms by which bacteria and viruses establish infection. His interests surround several issues in micro-host interactions with specific emphasis on the evolution of the pathogen and it's adaptation to hosts. The translational aspect of these investigations is in the development of improved diagnostic tests and methods for microbial characterization and identification, as well as studies into new generations of antimicrobial vaccines and therapeutics. A second focus in his laboratory is in the improvement of currently available diagnostic tools. As a result some investigations use state-of-the-art molecular methods including the design of novel high affinity ligands and sensitive back-end detection methods. These are coupled with classical and modified extraction protocols to improve recovery of agents of interest for accurate diagnostics. Dr. Sreevatsan is currently investigating the molecular diversity in mycobacteria, microbial population structure and functioning in pathogen induced environments, influenza virus ecology and evolution, and developing high affinity ligands to prion proteins to investigate the pathogenesis and new therapeutic modalities for infectious diseases.
