Paul S. Weiss graduated from MIT with SB and SM degrees in chemistry and from UC Berkeley with a PhD in chemistry. He is a nanoscientist and holds a UC Presidential Chair and is a distinguished professor of chemistry & biochemistry, bioengineering, and materials science & engineering at UCLA, where he was previously director of the California NanoSystems Institute. He holds visiting appointments at Harvard’s Wyss Institute and universities in Australia, China, Hong Kong, India, and South Korea. He studies the ultimate limits of miniaturization, developing and applying new tools and methods for atomic-resolution and spectroscopic imaging and patterning of chemical functionality. He and his group apply these advances in other areas including molecular devices, sensing, quantum information, precision medicine, microbiome studies, tissue engineering, cellular agriculture, and high-throughput gene editing. He led, coauthored, and published the technology roadmaps for the BRAIN Initiative and the US Microbiome Initiative. He has authored over 500 publications, holds over 40 patents, and has given over 1000 invited, plenary, keynote, and named lectures. He is involved in startups in biotechnology, food security, energy, entertainment, and healthcare. He was the founding editor-in-chief of ACS Nano. He has won awards in science, engineering, teaching, publishing, and communications, including: the NSF Presidential Young Investigator Award; BF Goodrich Collegiate Inventors Award; Sloan Fellowship; ACS Nobel Laureate Signature Award, Tolman Medal, Award in Colloid and Surface Chemistry, and Patterson-Crane Award; Guggenheim Fellowship; IEEE Nanotechnology Pioneer Award; and Sigma Xi William Procter Prize. He is a fellow of the American Academy of Arts and Sciences, American Association for the Advancement of Science, American Chemical Society, American Institute for Medical and Biological Engineering, American Physical Society, American Vacuum Society, Canadian Academy of Engineering, IEEE, Materials Research Society, National Academy of Inventors, and an honorary fellow of the Chinese Chemical Society and Chemical Research Society of India.
