Diane Lobsiger is an electrical instructor at Delta College in University Center, Michigan. She instructs students in the Skilled Trades-Electrician program, Wind Turbine Technology program, and Pre-Engineering program. In her prior work as a senior manufacturing controls engineer for 24 years, she gained a wealth of knowledge and extensive experience in the design, troubleshooting, specification writing, and approval of machine controls systems. Her expertise includes relay control systems, programmable logic controllers, human-machine interfaces, servo systems, adjustable frequency drives, and fluid power systems. She earned a Bachelor of Science in electrical engineering from Auburn University and a Master of Science in electrical engineering from Michigan State University. She recently obtained her Secondary Teaching Certification in mathematics and physics from Saginaw Valley State University. In her free time, she can usually be found fishing at her cabin.
