Research Interests

Generally speaking, my current research interests are studying high-dimensional math problems, mainly at the interface of probability, information theory, and combinatorics. Specifically, my research interests include:

• Entropic/functional/isoperimetric inequalities

• Packing and covering

• Information-theoretic methods and large deviations analysis
