Ullyot Public Affairs Lecture

In 1990 chemist Glenn Edgar Ullyot endowed a public lecture with the Philadelphia Section of the American Chemical Society. The goal: that this annual lecture would inform the audience of how chemistry, biology, and the sciences in general contribute to the public welfare.

In the years since, esteemed scientists, journalists, government and business leaders, and even Nobel laureates have addressed audiences at this popular lecture. It is presented jointly by the Science History Institute (where the lecture has been held since 1997), the Department of Chemistry at the University of Pennsylvania, the Department of History and Sociology of Science at the University of Pennsylvania, the Department of Chemistry and Biochemistry at the University of the Sciences, and the Philadelphia Section and Delaware Section of the American Chemical Society.

The 2022 Ullyot Public Affairs Lecture will be presented by Nobel laureate Frances Arnold on November 17, 2022.

Frances Arnold is the Linus Pauling Professor of Chemical Engineering, Bioengineering, and Biochemistry at the California Institute of Technology. She was awarded the Nobel Prize in Chemistry in 2018 for pioneering directed enzyme evolution and has used directed protein evolution for applications in alternative energy, chemicals, and medicine. Arnold was recently appointed cochair of President Biden’s Council of Advisors on Science and Technology. Other awards include the Charles Stark Draper Prize of the U.S. National Academy of Engineering (2011), the U.S. National Medal of Technology and Innovation (2011), and the Millennium Technology Prize (2016). She has been elected to the U.S. National Academies of Science, Medicine, and Engineering, and was appointed to the Pontifical Academy of Sciences in 2019. Arnold cofounded three companies in sustainable chemistry and renewable energy (Gevo, Provivi, Aralez Bio) and serves on the boards of several public and private companies. She earned a BS in mechanical and aerospace engineering from Princeton University and a PhD in chemical engineering from the University of California, Berkeley.

About the Sponsors

The Department of Chemistry at the University of Pennsylvania is composed of a dynamic community of researchers creating and disseminating new knowledge at the forefront of the chemical sciences. As an enabling science, chemistry is at the focal point of every important modern societal challenge. Our faculty and students engage these challenges daily on a local, national, and international scale.

The Department of History and Sociology of Science at the University of Pennsylvania uses the tools of the humanities and social sciences to study science, technology, medicine, and the environment. Through a broad range of scholarly projects, faculty research examines relations between the technical practice of scientists, engineers, medical researchers, and clinicians and the material, social, political, and cultural context in which those practices occur. Interdisciplinary study, faculty-student interaction, and individual mentoring characterize both the graduate and undergraduate programs.

The Department of Chemistry and Biochemistry at the University of the Sciences is the home of the chemistry, biochemistry, and pharmaceutical chemistry majors, and the chemistry, biochemistry, and bioinformatics minors. With expertise distributed over all five of chemistry’s primary areas, the faculty engage in diverse, award-winning teaching and research activities that prepare students for such future opportunities as employment in industry, science teaching, and postgraduate training in graduate schools, medical school, and law school.

The American Chemical Society is a nonprofit organization chartered by the U.S. Congress. With more than 158,000 members, ACS is the world’s largest scientific society and a global leader in providing access to chemistry-related research through its multiple databases, peer-reviewed journals, and scientific conferences. Its main offices are in Washington, D.C., and Columbus, Ohio. The Philadelphia Section and Delaware Section are cosponsors of the Ullyot Public Affairs Lecture.
