Karim Karim

Meet the Director of the Silicon Thin-Film Applied Research Group

Dr. Karim S. Karim is a Professor in the Department of Electrical and Computer Engineering at the University of Waterloo. He has secured more than $15M in research grant funding, trained over 40 PhD and MASc students, and has co-authored 250+ publications and 50+ patents.

He is a founder and Chief Technology Officer of KA Imaging, a University of Waterloo spinoff company that makes innovative X-ray detectors and systems for medical, veterinary, scientific and industrial markets. Dr. Karim has developed novel imaging devices and systems since 1998, and has both supported and founded multiple startups over the past two decades. One of his “color” X-ray innovations is now starting to replace black and white medical X-ray globally, while another is used in ultrasonic fingerprint sensors in mobile phones and tablets.
