Scott Diddams
Template:Short description Scott Diddams holds the Robert H. Davis Chair<ref>https://www.colorado.edu/ecee/scott-diddams</ref> at the University of Colorado Boulder, where he is also Professor of Electrical Engineering and Physics.John L. Hall<ref>Template:Cite news</ref> He carries out experimental research in the fields of optical frequency combs, precision spectroscopy, nonlinear optics, microwave photonics and ultrafast lasers. He was previously a group leader and Fellow of the National Institute of Standards and Technology (NIST) based in Boulder, Colorado.
While a postdoc in the lab of Nobel laureate John L. Hall, Diddams demonstrated the self-referenced optical frequency comb<ref>Template:Cite journal</ref> and subsequently used it to realize the first optical clocks.<ref>Adam, D. The times, they are a-changin'. Nature 421, 207–208 (2003). https://doi.org/10.1038/421207a </ref> Throughout his career, he has continued to pioneer the development of frequency combs in multiple platforms and use them in numerous applications--including astronomy, low-noise microwave synthesis, and spectroscopic sensing. He has also been active in the miniaturization of optical frequency combs and atomic clocks.<ref>Template:Cite news</ref><ref>Template:Cite news</ref>
He is a Fellow of Optica, American Physical Society, and IEEE. Among other awards, he is recipient of the 2017 IEEE UFFC Rabi Award,<ref>https://ieee-uffc.org/award/i-i-rabi-award#recipients-2017</ref> the Presidential Rank Award in 2021,<ref>https://www.opm.gov/policy-data-oversight/senior-executive-service/presidential-rank-awards/2021/presidential-rank-awards-2021.pdf Template:Bare URL PDF</ref> and the 2023 C.E.K. Mees Medal.<ref>Template:Cite web</ref> In 2025, Diddams was elected to the National Academy of Engineering.<ref>Template:Cite web</ref>
