In the last 20 years, fundamental concepts developed by researchers in the theory of computing field have transformed technology and society. Examples include the emergence of secure e-commerce from the invention of public-key cryptography, the fundamental impact on the development of quantum computing as a result of a theoretical quantum algorithm for factoring integers, and the sudden prominence of cryptocurrencies. Director, Simons Institute for the Theory of Computing, leading the centre for collaborative research on the foundations of computing, bringing researchers from academia and industry together for collaborative explorations of questions about the nature and limits of computing and algorithms, and their implications for data science, cybersecurity, scientific discovery, and society.
