Research Interests
I co-organize the Georgia Tech Stochastics Seminar (Thu @ 3:30pm, Skiles 006).
I am also active at the Probability Working Seminar (Tue @ 3:30pm, Skiles 006).
-
Mathematical statistics: high-dimensional & robust estimation, structural adaptation, hypotheses testing, nonparametric estimation.
-
Optimization theory: large-scale algorithms, minimax & nonconvex problems, acceleration, non-Euclidean geometry, lower complexity bounds.
-
Learning theory: fast rates / constant regret in statistical / online learning.
-
Signal processing: estimation with shift-invariant structure, super-resolution.
