Jennifer (Jen) Dionne is an American scientist and pioneer of nanophotonics. She is currently senior associate vice provost of research platforms at Stanford University, a Chan Zuckerberg Biohub Investigator, and an associate professor of materials science and engineering and by courtesy, of radiology. She serves as director of the Department of Energy's "Photonics at Thermodynamic Limits" Energy Frontier Research Center (EFRC), which strives to create thermodynamic engines driven by light, and she leads the "Extreme Scale Characterization" efforts of the DOE's Q-NEXT Quantum Science Center. She is also an associate editor of the ACS journal Nano Letters.[1] Dionne's research develops optical methods to observe and control chemical and biological processes as they unfold with nanometer scale resolution, emphasizing critical challenges in global health and sustainability.
Dionne was born October 28, 1981, in Warwick, Rhode Island, to Sandra Dionne (Draper), an intensive care unit nurse, and George Dionne, a cabinet maker. She grew up figure skating, but also enjoyed science and math. As a student at Bay View Academy, she was selected to be a student ambassador to Australia. She also participated in the Washington University Summer Scholars Program and the Harvard University Secondary School Program.
She attended Washington University in St. Louis, where she received bachelor's degrees in physics and systems science and mathematics in 2003. There, she served on the Mission Control of Steve Fosset's first attempted solo hot air balloon circumnavigation. She also worked as student lead of the Crow Observatory.
She then received her and doctoral degrees in Applied Physics from Caltech in 2009, advised by Harry Atwater. At Caltech, she was named an Everhart Lecturer, and awarded the Francis and Milton Clauser Prize for Best Ph.D. Thesis, recognizing her work developing the first negative refractive index material at visible wavelengths and nanoscale Si-based photonic modulators.[2] Before starting her faculty position at Stanford, she spent a year as a postdoctoral fellow in Chemistry at Berkeley and Lawrence Berkeley National Lab, advised by Paul Alivisatos.
Dionne began as an assistant professor at Stanford in March, 2010. In 2016, she was promoted to associate professor, and became an affiliate faculty of the Wu Tsai Neuroscience Institute, Bio-X, and the Precourt Institute for Energy. In 2019, she joined the department of radiology as a courtesy faculty. In 2019–2021, she was director of the TomKat Center for Sustainable Energy, and initiated their graduate student fellowship. In 2020, she became a senior fellow of the Precourt Institute and was appointed senior associate vice provost for research platforms. In her vice provost role, she is helping Stanford to redefine shared research facilities across the schools of engineering, medicine, humanities and sciences, earth sciences, and SLAC. She initiated the Community for Shared Research Platforms (c-ShaRP), which has enabled improved education, instrumentation, organization, staffing, and translational efforts in the shared facilities.[3]
In her research, Dionne is a pioneer in manipulating light at the atomic and molecular scale. Under Dionne's leadership, her lab helped to establish the field of quantum plasmonics. She also made critical contributions to the field of plasmon photocatalysis, including developing combined optical and environmental electron microscopy to image chemical transformations with near-atomic-scale resolution. Her work in plasmon catalysis could enable sustainable materials manufacturing, overturning the traditional trade-offs in thermal catalysis between selectivity and activity. Her group is also credited with developing the first high-quality-factor phase-gradient metasurfaces for resonant beam-shaping and beam-steering. Dionne uses this platform to detect pathogens, and view the intricacies of molecular-to-cellular structure, binding, and dynamics.[4]
