John R. Lawall

John Lawall is a physicist in the Microsystems and Nanotechnology Division in the Physical Measurement Laboratory. He received the BS in physics at Stanford University, where he did an honors thesis under the direction of Arthur Schawlow. Following his undergraduate education, he spent two years in Mali as a Peace Corps volunteer, teaching mathematics in a high school during the academic year and demonstrating the construction of wood-conserving mud stoves in the summer months. He subsequently went on to earn the PhD in experimental atomic physics at Harvard University with Francis Pipkin and Mara Prentiss, where he was supported by a fellowship from AT&T Bell Laboratories. Following the doctoral degree, he was the recipient of a Chateaubriand fellowship to do postdoctoral research at the Ecole Normale Supérieure in Paris with Claude Cohen-Tannoudji, Alain Aspect, and Michèle Leduc. He then came to NIST as a NRC Postdoctoral Fellow in the group of Bill Phillips, and has remained at NIST ever since. His research at NIST has been in the fields of high-precision interferometry, frequency combs, self-assembled quantum dots, and optomechanics. He spent five months as a Visiting Fellow at JILA in the group of Jun Ye. He commutes by bicycle and plays the viola with the Baroquean Strings at NIST.
