Biography Summary

Karim Karim is a Professor in the Electrical and Computer Engineering department, the Associate Director of the Center for Bioengineering and Biotechnology (CBB), a Researcher in the Waterloo Institute of Nanotechnology, as well as the Director of Silicon Thin Film Applied Research at the University of Waterloo.

Professor Karim’s research group is investigating circuit, device and process development for large area electronics in the field of digital X-ray imaging for biomedical and bioengineering applications. The group also performs pioneering research in hybrid amorphous selenium-CMOS digital imagers where recently, the group demonstrated the world’s first 5 um pixel pitch direct conversion digital X-ray imager that is capable of visualizing up to 60 lp/mm with high dose efficiency. Using this imager, his group is pioneering a phase contrast X-ray micro-CT imaging tool that has the potential to critically advance genomics by allowing the work to proceed in intact animals, tissues, and even single cells, which has not been possible in the past.

Professor Karim has received multiple awards and honours, including the 2009 Canadian Institutes of Health Research (CIHR) Science to Business Fellowship, the 2008 Ontario Early Researcher Award and is the founder and CTO of a recent UW spinoff company (KA Imaging).
