Prof. Alex Yasha Yi

Welcome to Integrated Nano Optoelectronics Laboratory!

We have a dynamic research team at University of Michigan, dearborn campus, energy institute at ann arbor campus and MIT microsystems technology laboratory. Our research is focused on integrated nano scale optoelectronics, nano photonics and nanoelectronics with applications on solid state on-chip Lidar for autonomous driving/IOTs, integrated micro sensors, biomedical sciences&engineering, photovoltaic cells/renewable energy, optical communication, quantum optics, solid state lighting/display/medical imaging, and OptoMEMS. 

Our lab has been awarded a variety of projects (> $ 3 million) from federal agencies and industries recently.

 We are recruiting: We are looking for highly motivated Ph.D students and Postdoc Associates, please send me an email if you are interested!
