Dr. Tim Henrich is an Associate Professor of Medicine at the University of California San Francisco. There he runs a laboratory that studies the HIV disease process and the development of treatment options for HIV patients. When the COVID-19 pandemic started Tim immediately turned his expertise on viral infection towards the study of the SARS-CoV-2 virus and its chronic consequences. He is a Co-Principal Investigator in Virology for the Long-term impact of infection with novel coronavirus study program at UCSF – the first rigorous, prospective study in the U.S. and perhaps globally focused on studying the biology of what is now known as Long COVID. The LIINC study has shared over 20,000 biospecimens across dozens of research collaborations focused on post-COVID conditions and with study samples and clinical data used to evaluate multiple mechanisms of Long COVID including SARS-CoV-2 viral and antigen persistence, microvascular dysfunction, microbial translocation, and reactivation of viruses including herpesviruses. Tim is also an expert in ImmunoPET-CT imaging: a form of imaging allows his team deep to map deep tissue reservoirs of viruses and T cell activity in patient tissue.
