Sotirios Liaskos

Sotirios Liaskos is an Associate Professor in the School of Information Technology at the Faculty of Science, York University. He is a leading researcher in requirements engineering and conceptual modeling, with a focus on goal models, empirical evaluation, and model-driven engineering.

Research Interests:

• Requirements Engineering
• Goal and Conceptual Modeling
• Empirical Software Engineering
• Model-Driven Design and Automation
• Uncertainty and Decision-Theoretic Reasoning in Models
• Applications in Blockchain and Reinforcement Learning

His recent work emphasizes the empirical validation of modeling constructs, the integration of decision theory into goal models, and the automated generation of secure workflows and AI training environments. He has led and co-authored numerous experimental studies on model comprehensibility and semantic quality.

Publication Trends: His publications consistently appear in top venues like ER, RE, and iStar. The last five years show a strong trend toward empirical evaluation of modeling languages, decision-theoretic goal models, and applications of goal modeling in emerging domains such as blockchain and reinforcement learning simulation design.

Scientific Contributions:

• Developed frameworks for empirical evaluation of modeling language ontologies (Peira framework).
• Advanced decision-theoretic approaches to goal modeling under uncertainty.
• Pioneered model-driven methods for generating blockchain simulators and reinforcement learning environments.
• Conducted foundational empirical studies on the comprehensibility of contribution links and visualization alternatives in goal models.

Advising and Collaboration: He has advised several researchers including Ibrahim Jaouhar, Wisal Tambosi, Mehrnaz Zhian, and Saba Zarbaf. He maintains a highly collaborative research profile with frequent co-authorship with John Mylopoulos, Shakil M. Khan, and other international researchers. He has served as a co-editor for multiple iStar workshop proceedings, indicating leadership in the goal-oriented requirements engineering community.

Labs and Teams: While no specific lab name is mentioned, his work is closely associated with research groups focused on requirements engineering and conceptual modeling, likely within York University’s software engineering research cluster. His collaborations span institutions in Canada, Europe, and beyond.
