Chen Hajaj
I am an Associate Professor and Head of the Data Science Track at Ariel University, where I lead research and education at the intersection of artificial intelligence theory and real-world deployment. I also serve as Head of the Faculty Review Board and NVIDIA University Ambassador.
My work focuses on translating AI into systems with measurable impact — spanning encrypted traffic analysis, medical decision support, and intelligent recommendation at scale. I have secured over $1.2 million in competitive funding and hold 4 patents in healthcare diagnostics, cybersecurity, and human behavior prediction.
I bridge academia and industry through partnerships with the Israel Innovation Authority, the Ministry of Innovation, Science and Technology, and leading technology companies.
