Abstract

It has been 2.5 years since Weisi left the DTG , and this 45 minute presentation gives an overview of 2 aspects of his work: low carbon wireless communications (green radio), and the science of cities. In the first part of the talk, he will be presenting key trends in wireless information technologies and show how his research has attempted to tackle the question: “how to grow wireless capacity with the smallest energy-cost expenditure?” In the second part, Weisi gives an overview of the next major area of cross-discipline research: urban science. Weisi is the co-director of the “Cities” research theme in Engineering, he is driving an international effort to use mathematics to make sense of the mechanisms inside cities. As the first phase of that approach, he is examining the role of mobile and fixed sensors that can extract big data from urban life. He is in the process of setting up living urban laboratories in New York. The purpose of the talk is to encourage collaboration and discuss new ideas.
