Medical Director: Dr. Michelle Noga

Dr. Michelle Noga is a radiologist trained at University of Alberta and British Columbia’s Children’s and Women’s hospital. She is currently an associate professor at the University of Alberta, department of radiology and diagnostic imaging, and a radiologist with Medical Imaging Consultants. Areas of interest include pediatric cardiac MRI and CT, post-processing of cross-sectional cardiac imaging, 3D visualization, rapid prototyping, pediatric airway, and finite element analysis.

Scientific Director: Dr. Pierre Boulanger

Operational and Computational Director: Dr. Kumaradevan Punithakumar

Dr. Kumaradevan Punithakumar received the B.Sc.Eng. (with First class Hons.) degree in electronic and telecommunication engineering from the University of Moratuwa and the M.A.Sc and Ph.D. degrees in electrical and computer engineering from McMaster University. From 2008 to 2012, he was an Imaging Research Scientist at GE Healthcare, Canada. He was the recipient of the Industrial Research and Development Fellowship by the National Sciences and Engineering Research Council of Canada in 2008, and the GE Innovation award in 2009. Areas of interest include medical image analysis and visualization, information fusion, object tracking, and nonlinear filtering.
