Dr. Gale S. Petrich is a principal investigator in the Research Laboratory of Electronics (RLE) at the Massachusetts Institute of Technology (MIT). He received the B.S.E.E., M.S.E.E, and Ph.D. in electrical engineering from the University of Minnesota in 1986, 1989, and 1991 respectively. He joined RLE in 1992 as a postdoctoral associate, and was promoted to Research Scientist in 1995 and Principal Research Scientist in 2001.
Dr. Petrich’s research involves the generation, manipulation and detection of light using III‑V compound semiconductor-based structures that are grown by molecular beam epitaxy. Active and passive photonic devices are fabricated from the heterostructures for possible integration into photonic integrated circuits.
