Biography

Jason W. Fleischer is a Professor in the Department of Electrical Computer Engineering at Princeton University. His research primarily focuses on nonlinear optics within the broader context of general wave physics. The emphasis of his work lies in addressing propagation problems in universal wave systems, taking advantage of the easy control that optical systems allow for input and direct imaging output. Through a strong mix of theory and experiment, his group investigates both fundamental nonlinear physics and advanced design challenges related to photonic applications. Key results from his studies include mappings that model optical observation of fluid behavior, which is typically difficult or impossible to visualize. His work also provides frameworks for discovering new optical physics. Furthermore, he explores how optical waves can carry information, leveraging propagation for dynamic signal processing. For example, nonlinear wave mixing leads to (intensity-dependent) energy transfer modes that enhance resolution, increase the field of view, and improve signal-to-noise properties. His research includes areas such as digital holography, noisy imaging, and biomedical optics, and he actively works on generalized computational imaging, including spatial nonlinearity in microscopy and phase retrieval applications.
