He has been a Director, UCSF Viral Diagnostics and Discovery Center, Faculty Member, Biomedical Sciences, QB3 Investigator. He received 2009 QB3 Rogers Family Foundation Award. He has more than 10 publications in reputed journals.    

His research focuses on the development of metagenomics-based technologies to identify viral etiologies of acute and chronic diseases in humans. This research consists of two major goals: (1) to explore the utility of pan-viral microarrays (Virochip) and high-throughput, “deep” sequencing in the detection and discovery of viruses associated with acute and chronic human illnesses, and (2) to characterize a novel human cardiovirus recently detected in clinical specimens by use of the technologies.
