Lei Bi is a Ph. D. candidate in Materials Science and Engineering Department of MIT. He works as a research assistant in the Magnetic Materials and Devices Group, advised by Prof. Caroline A. Ross, focusing on developing novel magnetic oxide thin films and integrated magneto-optical isolators for photonic integrated circuits.

At MIT, he developed several novel transparent ferromagnetic thin film systems as candidates for integrated optical isolators. He also experimentally demonstrated the prototype of an ultra compact optical isolator on an SOI platform.

Before joining MIT in 2006, he completed an M.S. and B.S. both in Materials Science and Engineering Department of Tsinghua University, China, in the year 2004 and 2006 respectively. His Master thesis was advised by Prof. Jiayou Feng, focusing on experimental research of light emission in silicon nanocrystals.

Lei Bi has authored and coauthored 14 refereed journal publications and 6 conference presentations since 2005. He also has 3 patents under application.
