Great Lakes Crystal Technologies (GLCT), a high-tech startup in Michigan’s Capitol Region, is pleased to announce a key addition to its management team.

Dr. Ramon Diaz joined GLCT in early June in the role of director of production for GLCT’s crystalline diamond materials product line. He recently completed his PhD in Electrical Engineering at Michigan State University (MSU) where his advisor was MSU Professor Tim Grotjohn, a co-founder of GLCT. His PhD studies focused on advancing the technology for manufacturing large area diamond materials. He also has previous experience teaching physics and statistics at the collegiate level, and he has prior early stage high technology startup experience.

Dr. Diaz, Dr. Grotjohn, and Dr. Quayle (GLCT chief scientist) have all worked closely together for the past several years both when Dr. Quayle worked as a post-doctoral research scientist in Professor Grotjohn’s group.

“Ramon brings important knowledge, skills and experience to our growing team and at a great time as we continue to progress on our mission to become the leading provider of semiconductor-grade diamond materials,” said Dr. Keith Evans, GLCT’s president and CEO.
