My research explores the fundamental limits of datalimited computational problems. How efficiently can we recover signals from noisy samples? And how much space do we need to compute functions of large data streams? My work has given algorithms with tight, or neartight, sample complexities for a variety of such problems, along with corresponding lower bounds.
Examples areas of my research include:One nice feature of sample and space complexity is that (unlike time complexity) we have the tools to prove matching lower bounds. A large portion of my research is on proving such lower bounds. Strong lower bounds give us a target to aim for, guide how algorithms should be designed, and tell us when to stop looking for better algorithms and instead look for better problems.
