Understanding the spectral norm of random matrices is a problem of basic interest in several areas of pure mathematics (probability theory, functional analysis, combinatorics) and in applied mathematics, statistics, and computer science. While the spectral norm of classical random matrix models is well understood, existing methods almost always fail to be sharp in the presence of nontrivial structure. In this talk, I will discuss new bounds on the norm of random matrices with independent entries that are sharp under mild conditions.
