Theory and Algorithms
Theoretical computer science studies the foundations computing from a rigorous and mathematical point of view. Core topics include models of computing, design and analysis of algorithms, data structures, protocols and mechanisms, and lower bounds.
Our faculty study algorithms in many diverse areas (computational geometry & topology, graphs, optimization, approximation, randomization), data structures, cryptography and secure computation, economics and computation, complexity theory, foundations of machine learning, and applications to several areas including operations research, computational biology, parallel & distributed computing, and networking to name a few. Our research, in addition to its fundamental importance, has many near and long term applications in Computer Science and beyond.
Strengths and Impact
The group has an outstanding and prolific publication record in the top conferences and journals of TCS. The faculty have received several best paper awards and mentions. Some recent highlights of faculty awards: (1) ACM Fellow (Amato, Chan, Warnow), (2) AAAS Fellow (Jacobson), (3) George E Kimball Medal from INFORMS (Jacobson), (5) David F Baker Distinguished Research Award from Institute of Industrial and Systems Engineering (IISE) (Jacobson), (6) NSF CAREER Award (Garg, Mehta, Solomonik, Telgarsky), and (7) Chairs or Professorships (Chan, Chekuri, Erickson, Jacobson, Warnow).
The group has graduated several doctoral students who have gone onto excellent careers in academia and industrial research. The more recent academic cohort includes: Hsien-chih Chang (Dartmouth), Alina Ene (Boston U, NSF CAREER, Sloan Fellowship), Kyle Fox (UT Dallas, NSF CAREER), Sung jin Im (UC Merced, NSF CAREER), Nirman Kumar (U of Memphis), Hemanta Maji (Purdue), Ben Moseley (CMU, NSF CAREER), Amir Nayyeri (Oregon State U, NSF CAREER), Kent Quanrud (Purdue), Ben Raichel (UT Dallas, NSF CAREER), Jason Sauppe (U Wisconsin at La Crosse).
