Theoretical Foundations of Computer Science research at Drexel University's College of Computing & Informatics (CCI) explores the mathematical foundations of computing. CCI Computer Science research includes application domains such as algorithmic game theory, approximation algorithms, object recognition and computer vision, algorithmic fairness, programming languages, and computer algebra. CCI Computer Science faculty regularly publish in the top conferences in theoretical computer science (such as ACM Symposium on Theory of Computing, IEEE Symposium on Foundations of Computer Science, and ACM-SIAM Symposium on Discrete Algorithms) as well as the top conferences of the respective sub-areas (such as EC, PLDI, AAAI, IJCAI, and ICML) and interdisciplinary journals. Our Computer Science faculty work closely with students and runs the weekly theory reading group, which brings together faculty with graduate, undergraduate, and high school students, to discuss a variety of topics in theoretical computer science.
