Research Themes

Our research is organized into three major themes: Artificial Intelligence, Data Science, and Systems. Each theme has its own set of research goals and challenges. Our faculty focuses on making high impact contributions in the field as a whole by tackling key problems in these major directions to address many important applications to society. While our research areas are categorized into one of these themes, many reflect a diverse range of sub-topics and practical applications, which can often straddle these boundaries.

1. Artificial Intelligence (AI)

Artificial intelligence research focuses on studying and developing methods to understand and perform tasks that typically require human intelligence. AI encompasses a very wide range of techniques and approaches, which include machine learning, deep learning, natural language processing, knowledge representation, computer vision, robotics, and expert systems.
