# Randy Bartels

Randy Alan Bartels is an American investigator at the Morgridge Institute for Research and a professor of Biomedical Engineering at the University of Wisconsin–Madison. He has been awarded the Adolph Lomb Medal from the Optical Society of America, a National Science Foundation CAREER award, a Sloan Research Fellowship in physics, an Office of Naval Research Young Investigator Award, a Beckman Young Investigator Award, and a Presidential Early Career Award for Science and Engineering (PECASE). In 2020 and 2022, he received support from the Chan Zuckerberg Initiative to develop microscope technologies for imaging tissues and cells.

## Early life and education

Bartels earned a BS in Electrical and Computer Engineering from Oklahoma State University in 1997. During summer breaks, he participated in research experience for undergraduate programs, studying semiconductor thin film growth and characterization at Iowa State University, fabricating and modeling ion-exchanged waveguides at the Gérard Mourou Center for Ultrafast Optical Science at the University of Michigan, and building quasi-continuous-wave diode pumped solid state lasers at Lawrence Livermore National Laboratory. Bartels received his Ph.D. from the University of Michigan in 2002. After starting his Ph.D. work at the University of Michigan, he moved to JILA in Boulder, CO, where the bulk of his thesis work was performed. He worked on the development of ultrafast lasers, coherent control of quantum systems, and the study of extreme nonlinear optics. This work contributed to the development of attophysics by manipulating the strong-field dynamics of atomic electron wave functions with ~10 attosecond precision. Attosecond physics was recognized by the Nobel Prize in Physics in 2023, conferred to three scientists “for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter.”
During his graduate career, Bartels was supported by a National Defense Science and Engineering Graduate Fellowship and received the Optical Society of America’s New Focus Student Research Award, and a JILA Scientific Achievement Award, as well as the IEEE Photonics Society Graduate Fellowship.

## Career and research

Bartels began his independent research career at Colorado State University, where he was awarded a Monfort Professorship, and held joint appointments in the Department of Chemistry and in the School of Biomedical Engineering. He began working on strong-field control of molecular rotations and vibrations and demonstrated ultra-sensitive detection of molecular coherences for spectroscopy and microscopy. His group developed vacuum ultraviolet light laser sources and optical systems, as well as stable optical comb sources in the mid infrared spectral region.
In 2023, Bartels joined the Morgridge Institute for Research as an Investigator and the University of Wisconsin–Madison as a professor of Biomedical Engineering. His research involves the development of spectroscopy and microscopy techniques and applications and the development of ultrafast fiber lasers for use in these applications.
Bartels is a Fellow of the Optical Society of America and of the American Physical Society. He serves on the Editorial Board of Applied Physics Letters, Photonics, as an editor for Optics Communications, and as an Associate Editor for Science Advances.
