# Charles Radin

Charles Lewis Radin is an American mathematician, known for his work on aperiodic tilings and in particular for defining the pinwheel tiling and, with John Horton Conway, the quaquaversal tiling.

## Education and career

Radin did his undergraduate studies at City College of New York, graduating in 1965, and then did his graduate studies at the University of Rochester, earning a Ph.D. in 1970 under the supervision of Gérard Emch. Since 1976 he has been on the faculty of the University of Texas at Austin.

## Awards and honors

In 2012 he became a fellow of the American Mathematical Society.
