Juejun Hu

Professor Juejun Hu is the John F. Elliott Professor and Professor of Materials Science and Engineering at the Massachusetts Institute of Technology. He leads the Photonic Materials Group, where his research focuses on developing novel materials and devices that exploit interactions between light and matter. His work spans a wide range of applications, including on-chip sensing and spectroscopy, semiconductor device fabrication, and advanced manufacturing of photonic systems. A major theme of Professor Hu’s research is the development of miniaturized, robust, and mass-producible optical sensors enabled by digital Fourier transform technologies, with applications in industrial process control, medical imaging, and space systems. His group is also a pioneer in optical phase change materials and meta-optics, creating reconfigurable optical devices that can be dynamically programmed for specific functions. Additional research directions include flexible and polymer photonics for biomedical monitoring and high-speed data communications, optical systems for imaging and sensing in consumer and automotive electronics, and chip-scale magneto-optical isolation for next-generation optical communication and navigation systems.
