6:05 PM - 6:45 PM: In Memoriam: 2022 SPIE Gold Medal Winner: Michael W. Berns, Beckman Laser Institute and Medical Clinic (United States)


In August 2022, about a week before he was due to receive the highest honor of SPIE - the SPIE Gold Medal, Michael Berns passed away at the age of 79. In place of the talk he had been preparing to give, we are revisiting a wonderfully retrospective talk he gave at the conference last year.

Using the photonic toolbox to study chromosomes: 50 years in search of an answer!

Abstract: Little did I know that when I published our first laser microbeam paper on chromosome surgery in 1969, that 50 years later I would still be doing that—trying to explain the inexplicable result we saw back then. The path to an answer of why cells with partially photon-ablated chromosomes could reproduce and maintain the photon-induced deletion in the clonal population of cells, was a path that was solely possible by the parallel development of additional tools in the photonic toolbox. Development of digital-based imaging technologies, GFP-based molecular fluorescent probes, and an evolution of optical manipulation tools (photonic scissors and tweezers) have been combined to provide a tantalizing answer to the question of why cells can divide and form clones following removal of a segment of their DNA.

Michael Berns was the Distinguished Arnold and Mabel Beckman Professor at the University of California, Irvine. He was co-founder of the non-profit (501c-3) Beckman Laser Institute and Medical Clinic (with Arnold O. Beckman), a premier center for biophotonics where basic research and patient treatment occur under the same roof. Berns published 500 articles in leading journals, six books, and holds sixteen patents. His books and publications have been published in 13 different languages and he has been featured in National Geographic and Scientific American magazines five times. He received the UCI Medal, the highest honor of the University. He was foreign member of the Royal Norwegian Academy of Sciences and Letters, and Fellow of the British Royal Society of Biology. and Royal Society of Medicine. In 2021, he published a full length historical fiction novel, The Tinderbox Plot, which accurately predicted the events of January 6, 2021.

6:45 PM - 7:15 PM: Quantum science and metrology


Jun Ye, JILA, Univ. of Colorado (United States)

Precise engineering of quantum states of matter and innovative laser technology are revolutionizing the performance of atomic clocks and metrology, providing new opportunities to explore emerging phenomena, test fundamental symmetry, and search for new physics. The recent work of measuring gravitational time dilation at the sub-millimeter scale highlights exciting prospects for new scientific discovery and technology development.

Jun Ye is a Fellow of JILA, a Fellow of NIST, a member of the National Academy of Sciences, a Fellow of APS, and a Fellow of OSA. His research focuses on the frontiers of light-matter interactions that include precision measurement, quantum science, and ultracold matter. He has co-authored 400 scientific papers and delivered 600 invited talks. Honors include Breakthrough Prize in Fundamental Physics, Niels Bohr Institute Medal of Honour, Herbert Walther Award, Julius Springer Prize, Micius Quantum Prize, N.F. Ramsey Prize, I.I. Rabi Award, US Presidential Rank Award (Distinguished), and four Gold Medals (U.S. Commerce Department).
