Dr. Alex Mariakakis is an Associate Professor in the Department of Computer Science at the University of Toronto. He runs the Computational Health and Interaction (CHAI) lab, which leverages ubiquitous technologies like smartphones and wearables to address problems related to people’s health. Using sensor data collected from momentary assessments or passive recordings, I employ signal processing and machine learning to generate digital biomarkers related to a person's physiology, context, and behavior. My work also spans other topics at the intersection of ubiquitous computing and human-computer interaction such as mobile interaction, user-centered design, and novel sensing techniques.

He is a recipient of the CHCCS HCI Early Career Researcher Award. As an Affiliate Scientist at KITE Research Institute and an Education Faculty Affiliate within T-CAIREM, he leverages his passion for digital health to influence the clinical landscape in the Greater Toronto Area. He is also currently a Faculty Fellow at AXL, a Toronto-based venture studio that aims to accelerate Canadian innovation in human-centric AI.
