Arthur L. Horwich

Arthur L. Horwich is a Sterling Professor of Genetics and Pediatrics at the Yale School of Medicine and a Howard Hughes Medical Institute investigator since 1990. His groundbreaking research on chaperonins, particularly HSP60 and its bacterial homologue GroEL, has revolutionized understanding of protein folding mechanisms in mitochondria and cellular compartments. He has held academic positions at Yale since 1984 and is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, and the National Academy of Medicine.

Education:

• A.B. in Biomedical Sciences, Brown University (1972)
• M.D., Brown University (1975)
• Internship/Residency in Pediatrics, Yale University
• Postdoctoral Fellow, Salk Institute for Biological Studies (1978-1981)

Research Interests: Arthur L. Horwich's work focuses on chaperonin-mediated protein folding, mitochondrial protein import pathways, and the structural-functional analysis of HSP60/GroEL complexes. His studies have elucidated how dynamic chaperonin assemblies assist protein folding under normal and stress conditions, bridging biochemistry, genetics, and cell biology.
