Appointment calendar — to set up a meeting, please consult my public calendar (Google log-in required) and send an email with proposed times.

I work in machine learning focusing on ML applications to patient chart data, computer vision, and applied statistics and take on data science consulting projects. I teach in the Division of Engineering Science at the University of Toronto, and collaborate with the Li Ka Shing Centre for Healthcare Research, Analytics, and Training at St. Michael's Hospital in Toronto.

My last name is pronounced ger-JOY, with a hard "g", and with the "J" pronounced like the "s" in "measure."
