I am a faculty member and Director of the Information Systems Program at the School of Business Administration, Bar-Ilan University. My research develops AI-based analytical models for understanding social, organizational, biomedical, and mental-health processes and for supporting scientific research and business decision-making. I work at the intersection of big data analytics, complex network analysis, graph mining, social media analytics, machine learning, natural language processing, computational biology, psychological medicine, and health informatics. Recent projects include AI-enabled detection of hidden medication side effects, childbirth-related PTSD screening from narratives and clinical data, knowledge graphs for biomedical discovery, and modeling information spread and collective behavior in online communities.
