Ali Tosyali

Assistant Professor of Management Information Systems
Rochester Institute of Technology

I am an assistant professor of management information systems at the Rochester Institute of Technology. My research interests lie broadly at the intersection of network science, machine learning, and complex systems, driven by applications in financial services analytics, social network analysis, opinion mining and analysis, digital platforms, and business analytics.

In my spare time, I enjoy riding my motorcycle, coding, playing baglama (a folkloric instrument), sports, and woodworking.
