Research at Yale CS

At Yale Computer Science, our faculty and students are at the forefront of innovation and discoveries.  We conduct ground-breaking research covering a full range of areas in theory, systems, and applications. 

Our department is currently in the middle of substantial growth. Data and Computer Science is listed as one of the top five Science Priorities in Yale’s recent University Science Strategy Committee Report. Yale’s School of Engineering and Applied Science is also launching a substantial initiative in Artificial Intelligence, broadly construed, that will include research in the foundations of AI, in applications and technology, and in societal and scientific impacts. 


Interdisciplinary Centers & Initiatives

Computer Science has also grown beyond its own bounds to become a multi-disciplinary field that touches many other sciences as well as arts and humanities: physics, economics, law, management, psychology, biology, medicine, music, philosophy, and linguistics. They have also led to interdisciplinary research centers.
