Scalable. Interactive. Interpretable.
At Georgia Tech, we innovate scalable, interactive, and interpretable tools that amplify human's ability to understand and interact with billion-scale data and machine learning models. Our current research thrusts: human-centered AI (interpretable, fair, safe AI; adversarial ML); large graph visualization and mining; cybersecurity; and social good (health, energy).

Data and Visual Analytics

Data and Visual Analytics (DVA) is data science course at Georgia Tech, for both graduate (as CSE6242) and undergraduate students (as CX4242). CSE 6242 is a required core course of the Master of Science in Analytics (MSA). In Spring 2018, the campus version of the course was "mirrored" and offered as a core course of the Online Master of Science in Analytics (OMS Analytics) program. In Fall 2018, the online offering was further expanded to the Online Master of Science in Computer Science (OMS CS) program. Instructors: Dr. Mahdi Roozbahani (since Fall 2019) and Prof. Polo Chau (since Spring 2013).
