Hamman is completing his doctoral studies as a Ph.D. Candidate and Researcher in the Department of Computing Science at the University of Alberta under the supervision of Dr. Osmar R. Zaïane. His research focuses on estimation, evaluation and dissemination of trust and privacy in health social media by application of text processing, algorithmics, and machine learning techniques. Specifically, he is developing algorithms and methodologies for quantifying objective versus subjective trust ratings, including computationally evaluating the veracity of health claims and advise on social media.

Hamman is a member of the Canadian Artificial Intelligence Association (CAIAC), IEEE, Digital Health Canada, and the Association for Computing Machinery (ACM), including SIGAI and SIGWeb.
