Meet the Professors

Bill Kellerhals
Instructor, Photonics

Teaching full time at CLC since: 2012; previously taught for seven years as a CLC adjunct. He also taught engineering, navigation and weapons systems courses at Northwestern University and Illinois Institute of Technology. Professor Kellerhals also taught laser operation and maintenance courses to technicians and customers in the coding and marking industry. He was trained as a nuclear engineer and served in three submarines during 23 years in the U.S. Navy.

Subjects taught at CLC: Applied mathematics, basic algebra, geometry, fundamentals of light and lasers, photonics, fundamentals of AC and DC circuits.

Education: B.A. and M.E.M., Northwestern University.

Main goal in teaching: I strive to stimulate in students an inquisitiveness and a desire to understand how all things involving light actually work. Students are actively engaged in practical, hands-on exercises and projects to promote deeper levels of understanding and retention. I maintain an open, questioning environment that encourages all reasonable experiments. In addition, I interweave real-world experiences and practical life skills with the subject material. There are daily opportunities to reinforce leadership, teamwork and responsibility.
