text: # Ron Donagi
  
  Ron Yehuda Donagi (born March 9, 1956) is an American mathematician, working in algebraic geometry and string theory.
  
  ## Career
  
  Donagi received a Ph.D. in 1977 under the supervision of Phillip Griffiths from Harvard University (On the geometry of Grassmannians). Currently, he is a professor at the University of Pennsylvania.
  
  From 1981 to 1982, from 1996 to 1997 and in 2013 he was at the Institute for Advanced Study, where he worked with Edward Witten. In the 1980s Donagi applied algebraic geometry to string theory and related theories such as supersymmetric Yang-Mills theories in order to develop models for heterotic string theory from suitable compactifications. Among his achievements in classical algebraic geometry are his work on the Schottky problem and generalizing the Torelli theorem.
  
  He is a fellow of the American Mathematical Society.
