About the grantee

At the start of the COVID-19 pandemic, the Sigal lab pivoted to SARS-CoV-2 research and was the first to describe the escape of the Omicron variant from previous immunity.

Sigal received his Ph.D. in Systems Biology from the Weizmann Institute of Science in Israel and was a Postdoctoral Fellow with the Nobel Laureate David Baltimore at the California Institute of Technology, where he worked on HIV cell-to-cell spread and its effects on antiretroviral therapy.
