Research and Clinical Interests

My interests include the use of metagenomics-based strategies (the Virochip pan-viral microarray and deep sequencing) for the diagnosis and discovery of viruses associated with a variety of acute (e.g. hepatitis, encephalitis, respiratory illness, gastroenteritis) and chronic (e.g. cancer) disease states. Specific ongoing projects in the laboratory include:

  1. Culturing and virological characterization of a novel human cardiovirus, with efforts to generate an infectious clone and clone the receptor
  2. Development of comprehensive tools (Virochip, PLEX-ID, and deep sequencing) for diagnosis of viral encephalitis and meningitis
  3. Broad-based detection of infectious agents in blood by microarrays and deep sequencing
  4. Development of rapid, point-of-care microarray diagnostics for viral pathogens
