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

Ms. Laurey Wyble joined GLCT in early May in the part-time role of director of finance. She has over 2 decades of executive experience in starting and leading the finance and operations of small companies. She is currently the operations manager for Opti O2, a high technology spinout of Michigan State University located in the VanCamp Incubator + Research Labs where GLCT is also located.

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-doc in Professor Grotjohn’s group (mid-2018 to mid-2020) and after Dr. Quayle left MSU to join GLCT last summer (2020).

“Laurey and Ramon bring 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.
