个人简介
His research in the last decade has revolved around the following two themes.
1. Fine-grained complexity, and exponential algorithms for hard problems: A primary focus has been to understand the time complexity and the relation between the computational complexity of various computational problems, particularly lattice problems. This includes both finding faster algorithms, and proving lower bounds under reasonable complexity theoretic assumptions.
2. Randomization has played a very important role in many areas of computer science. In practice, a source has some entropy, but is not uniformly random. The goal of transforming these imperfect random sources into perfectly random bits has, over the last few decades, led to a large body of research on the theory of randomness extractors and related primitives, and their applications in classical areas like privacy amplification, and tamper-resilient cryptography. Some of his recent research centers around improving construction of such extractors in various settings, and their applications.
