Theory
Yung is recognized for contributions to cryptography and its applications in information technology systems.
Machine learning systems often assume that the data they learn from is mostly trustworthy. But what happens when that data is deliberately corrupted?
Henry Yuen, Srivani Family Associate Professor of Computer Science, explained quantum computing to ABC News Correspondent Elizabeth Schulze: the basics of what it is, how it might prove useful, and what the world should be wary of.
About
The group does research on the fundamental capabilities and limitations of efficient computation.
In addition, they use computation as a lens to gain deeper insights into problems from the natural, social, and engineering sciences.
The group is highly collaborative, both within Columbia and among peer institutions. They hold a weekly Theory Lunch and a bi-weekly Student Seminar. Most graduate students have (at least) two advisors and collaborate with several professors and other students. Some of the faculty are cross-listed with the IEOR department and the Data Science Institute.
