Kristan Corwin (Fed)

Division Chief

Dr. Kristan Corwin is chief of the Applied Physics Division in the Physical Measurement Laboratory (PML) at the National Institute of Standards and Technology (NIST). The Division, located in Boulder, CO, is responsible for laser metrology, quantum metrology, quantitative imaging, and other application of photonic and magnetic technologies.

Dr. Corwin received a B.S. in Physics from the State University of New York at Buffalo in 1993, and earned both a M.S. and Ph.D. degree at the University of Colorado in laser trapping and cooling under the direction of Nobel Prize Winner Carl Wieman. After a postdoctoral position at École Normale Supérieure in ultracold quantum gasses with Christophe Salomon, she joined NIST Boulder Laboratories as a National Research Council postdoctoral fellow working with optical frequency combs. From 2003 – 2019 at Kansas State University she rose to the positions of Ernest K. and Lillian E. Chapin Professor of Physics and then Associate Dean for Research in the College of Arts and Sciences. Her research interests center on in nonlinear optics, frequency metrology, and novel laser systems, emphasizing gas-filled hollow optical fibers.

She is a Fellow of Optica (formerly the Optical Society), has co-authored more than 60 peer-reviewed publications, holds several patents, received multiple teaching awards, and has served as principal investigator for many millions of dollars of research grants, including leading a Research Experience for Undergraduates (REU) program. In 2015, she was a visiting fellow at JILA, University of Colorado and NIST. She formerly chaired the American Physical Society Division of Laser Science (APS DLS) and received the APS Five Sigma Physicist Award in 2019.
