Biographical Sketch

Kleppner’s research interests include precision measurements, fundamental constants and experimental studies with Rydberg atoms including cavity quantum electrodynamics and quantum chaos. With his colleague Thomas J. Greytak he helped to pioneer the field of Bose-Einstein condensation and quantum gasses. They succeeded in demonstrating Bose-Einstein condensation in atomic hydrogen in 1998.

With his colleagues, he founded the MIT-Harvard Center for Ultracold Atoms in 2002. In his teaching activities, Kleppner started a high-level mechanics course for gifted freshmen that became a permanent part of the physics curriculum. He and his colleague Robert J. Kolenkow wrote a textbook for that course in 1973, An Introduction to Mechanics, which has recently come out in a second edition.
