Panos’ research program studies how information systems and technological artifacts affect the user behavior and transform business and society.
His research focuses on personalization, mobile and social commerce, and online education.
Much of this research is grounded in big data employing data science and machine-learning techniques to leverage the abundance of unstructured data in social media, while combining these approaches with more conventional econometric and other quantitative methods as well as experimental research designs.
