Welcome! We are the research group of Jen Dionne, Associate Professor of Materials Science and Engineering at Stanford University. We are a diverse team of materials scientists, chemists, applied physicists, electrical engineers, chemical engineers, bioengineers and mechanical engineers, researching new ways to control light-matter interactions.
We imagine a world where diseases like cancer, Alzheimer's and tuberculosis are detected and cured with light; where solar cells provide abundant clean energy; and where cell phones compute at the speed of light. We then strive to make that future a reality through development of new nanophotonic materials, methods, and devices.
Please feel free to navigate this site or contact us for more information!
What is a typical day like for a researcher in our group? Check out our videos to learn more about our science and our culture. If you like what you see and want to join our team, please send us your resume. We're always on the lookout for smart, creative people.

Featured Research
I. Imaging and controlling light-induced chemical transformations at the nanoscale:
Dayne, Briley, Daniel and Jen present a riveting account of our labs past 10 years of research combining optically coupled electron microscopy with plasmonic photochemistry. We review how the unique capabilities of the Dionne lab let us visualize chemical reactions, and the unique influence that light has on them.
II. Lanthanide-Doped Nanophosphors as Optical Labels:
Dayne and Stefan show that a library of lanthanide-doped alkaline-earth rare-earth fluorides are an effective nanophotonic platform for single-particle STEM-CL and discover a few surprising twists along the way!
III. Chiral Metasurface for Spin-polarized Raman Lasing:
Jefferson and coauthors present an intrinsically chiral metasurface for spin-polarized Raman lasing, which prevents emitted light from re-entering the laser cavity and results in a self-isolated laser. The ability to incorporate optical isolation directly into a light source eliminates the need for bulky isolation components and paves the way for more compact photonic networks and nonlinear optics.
