Arthur Horwich received his A.B. and M.D. from Brown University. Following a pediatric residency at Yale, Horwich did two postdoctoral fellowships, first with Tony Hunter and Walter Eckhart at the Salk Institute and second with Leon Rosenberg at Yale, before joining the Yale faculty.

Currently, Horwich is Sterling Professor of Genetics and Pediatrics at Yale School of Medicine and an investigator of the Howard Hughes Medical Institute. He is interested in understanding how chaperonins promote the correct folding of proteins in the cell. More recently, Horwich has focused his efforts on understanding the consequences of protein misfolding, particularly in ALS, or Lou Gehrig’s disease.

Horwich is a member of the National Academy of Sciences and has received numerous awards for his work including the Gairdner International Award. Together with his longtime collaborator Franz-Ulrich Hartl, Horwich has been awarded the Wiley Prize, the Louisa Gross Horwitz Prize and the Albert Lasker Award for Basic Medical Research, among other prizes.
