Professor of Electrical and Computer Engineering. Director, Program in Material Science and Engineering.

Research interests: Application and development of analytical and computational methods for studying emerging, fundamental, and practical problems at the intersection of quantum and classical nanophotonics. Control and design of thermal emitters and absorbers, modeling fluctuation-induced electromagnetic phenomena in complex nanostructures and design of low-power, wavelength-scale nonlinear devices.

Matrix of fluorescent particles with pores that open and close — Sujit Datta’s research group received funding to develop leaf-inspired soft materials that someday could allow robots to efficiently transfer water and heat. Shown here are microscopic slices at different depths through a mesoporous thermo-responsive hydrogel that will form the basis of artificial leaf stomata that are programmed to dynamically open and close in response to sunlight or heat. Black circles show large voids in the hydrogel structure; white shows fluorescent particles embedded in the hydrogel matrix.

Artificial leaves, floating breakwaters and musical memories are among recipients of 2021 innovation grants

Princeton researchers, led by Alejandro Rodriguez, have uncovered new rules for how objects absorb and emit light. The work resolves a longstanding discrepancy between large and small objects, unifying the theory of thermal radiation across all scales and boosting scientists' control in designing light-based technology.
