Jesse Hoey

Jesse HoeyAssociate Professor Hoey works in artificial intelligence, affective computing, and health informatics. He is primarily interested in developing computational models of human interactions with machines, and in using these models to build artificially intelligent applications in healthcare. This research involves four main aspects. First, he works on decision theoretic planning, particularly on Markov decision processes (MDPs), and their partially observable counterparts, POMDPs. He is interested in learning these models from data, and on solving them, particularly for large state, action, and observation spaces. Second, he works on sensor-based recognition of human behaviour (including gesture, facial expression and gait/body posture) from dynamic sensor streams (including video). He is interested in task-oriented sensor stream analysis (e.g. computer vision), in which the goal is to optimize over the action/policy space for an automated agent. Third, he works on computational models of social and emotional behaviours of humans. This work integrates sociology, social psychology, and affective computing. Lastly, he uses sensors, decision theoretic models, and computational social science, to build assistive systems for persons with physical and cognitive disabilities. In particular, he is interested in systems that help a person with dementia during activities of daily living (ADL) using cameras and other sensors to inform decision processes with multiple and competing objectives. He is particularly interested in detecting and responding to emotional states of persons with these assistive technologies. Professor Hoey's research is funded in part by the Canadian Foundation for Innovation, the American Alzheimer's Association and the Natural Sciences and Engineering Research Council of Canada. He is co-investigator on the AGE-WELL Networks of Centers of Excellence (NCE, 2015-2018). He collaborates closely with researchers in Canada (UBC, Toronto, Guelph), the USA (Duke, Indiana), the UK (Newcastle, Dundee, Belfast, Heriot-Watt, Edinburgh), France (INRIA/Sophia-Antipolis), Germany (PotsdamBielefeld), and Mexico (Puebla, Cuernevaca, Ensenada).
