Charles M. Rice (born August 25, 1952) is an American virologist best known for his laboratory research on the hepatitis C virus. Born in Sacramento, California, Rice has spent much of his career investigating how the virus replicates and how infection can be interrupted. His experimental systems provided a way to study viral replication in cell culture and to test antiviral compounds, a crucial step toward the development of modern treatments.

Early life and academic posts

Rice trained and worked in virology and molecular biology before joining the faculty at the Rockefeller University, where he is a professor of virology. Over decades of laboratory research he established methods that allowed scientists to generate and analyze infectious hepatitis C genomes under controlled conditions, clarifying the virus's life cycle and vulnerability to drugs.

Key research contributions

  • Demonstrating strategies to replicate hepatitis C viral RNA in cultured cells, enabling direct study of viral replication and pathogenesis.
  • Producing infectious clones and experimental systems used to screen antiviral compounds and to understand viral assembly and release.
  • Providing foundational knowledge that accelerated the development of direct-acting antivirals that can cure most hepatitis C infections.

Rice's laboratory work bridged basic virology and translational research: by revealing how hepatitis C reproduces and persists, it helped transform diagnosis, blood safety, and treatment strategies for millions worldwide.

Recognition and impact

For his role in advancing understanding of hepatitis C, Rice has been elected a Fellow of the American Association for the Advancement of Science and is a member of the National Academy of Sciences. He served as president of the American Society for Virology (2002–2003). In 2020 he shared the Nobel Prize in Physiology or Medicine with Michael Houghton and Harvey J. Alter for discoveries that led to the identification and characterization of the hepatitis C virus.

Rice's work is widely cited in virology and public health discussions because it exemplifies how detailed molecular study of a pathogen can lead to effective therapies and safer blood supplies. His contributions remain central to ongoing efforts to prevent, diagnose, and treat viral hepatitis globally.
