PhD | hassanzadeh@dal.ca


I am a recent PhD graduate in Computer Science from Dalhousie University and open to new opportunities. I graduated with a MSc. in Information Technology Engineering (eCommerce) from Amirkabri University of Technology (Tehran Polythechnic) in 2013.



My present research interest is at the intersection of Artificial Intelligence, Data Analytics, Logic, and the Semantic Web with applications in healthcare and finance.

As my PhD thesis, I developed a SEmantics-based Data ANalytics (SeDan) framework implementing plausible reasoning over knowledge graphs. Our framework provides an exploratory approach to ‘Big’ data analytics deriving meaningful insights by turning collected data into actionable knowledge.

Recently, I was also involved in a Natural Language Processing research project, a subject which has always been an interest of mine. Prior to this, I have worked in and am still passionate about Data Mining, Trust and Reputation Mechanisms, Social Network Analysis, and Financial Engineering.

Thank you for stopping by! If you want to know more about my previous and present work and experience please scroll down or do not hesitate to drop an email to hassanzadeh@dal.ca
