Stylianos Loukas Vasileiou
Assistant Professor, Department of Computer Science
New Mexico State University
Hey there! I’m Stelios, currently an assistant professor of AI and CS at NMSU. I lead the Laboratory for Human-AI Interaction & Psychology, where we explore questions such as how human-AI synergy can lead to “better” decisions (what does better mean, you ask? 🤷) in domains like policymaking.
Prior to joining NMSU, I completed my PhD at the McKelvey School of Engineering at Washington University in St. Louis, supervised by the amazing William Yeoh. Many epochs ago, I received a MSc. in Artificial Intelligence from the University of Southampton (UK), supervised by Long Tran-Thanh, a MSc. in Applied Mathematics from the University of Glasgow (UK), supervised by Radostin Simitev, and finally a BSc. in Statistics and Actuarial-Financial Mathematics from the University of the Aegean (GR), supervised by Nikolaos Kavallaris.
New students: I am unfortunately not recruiting at the moment.
