Meet the Professors

Steven Dulmes
Professor Emeritus, CAD/CAM
T126
847/543-2000 33544
eng526@clcillinois.edu


Specialties: Lasers, photonics and optics; computer aided design; mechatronics (pneumatics and hydraulics). Professor Dulmes started CLC’s laser, photonics and optics program and serves as chair.

Teaching full time at CLC since: 1987; also has worked in industry as a hydraulics engineer and a CAD/CAM engineer who has trained engineers on CAD technology. Professor Dulmes has given several presentations on photonics at national conferences and for U.S. senators and Congressmen.

Courses taught at CLC: Most CAD courses, C programming, lasers and optics, drafting, engineering graphics, hydraulics, pneumatics, mathematics and Excel.

Education: B.S., Purdue University; M.S., DePaul University.

What inspires me most about my field: Working with some of the best people I have ever met, engaging students in the subject and working at the forefront of technology. Light, as being the first thing created is just now being applied to almost everything we touch and applying the technology in its many forms is intriguing. I have also enjoyed connecting with students as advisor of the Campus Crusade for Christ club for over 23 years.


Bill Kellerhals
Instructor, Photonics
T202
847/543-2616
bkellerhals@clcillinois.edu


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.
