I received my Ph.D. in Mathematics under Bernd Sturmfels in 2011 from the University of California, Berkeley, where I analyzed singularities in statistical models over large data sets through the lens of modern algebraic geometry. This work was continued at Stanford University in a one-year DARPA postdoctoral collaboration with Andrew Ng’s lab to explore mathematical challenges in deep learning. In 2012, I returned to Singapore to join the Institute for Infocomm Research (A*STAR) where I started the Sense-making Group in the Sense and Sense-abilities (S&S) programme. The group focused on exploiting machine learning techniques in sensor networks to create resource-efficient algorithms that exhibit higher-order intelligence. Before joining SUTD, I oversaw deep science activities in S&S as the Deputy Head for Research.
Beyond basic research, I worked closely with government and industry partners such as NEA, HDB and Sky Greens in several urban projects. These projects received both local and international recognition such as the MTI Borderless Silver Award 2015 and the World Smart Cities Award Finalist 2014. I was also appointed by the Science and Engineering Research Council (SERC) in A*STAR to lead a multi-agency panel of experts in developing future roadmaps for Data-Driven Research and Future Computing Paradigms.

My primary research goal is to understand how learning occurs within large systems. My areas of interest include algebraic geometry, statistical learning, neural networks, homotopy type theory and the Internet of Things. I am currently focused on two tasks. The first is to develop efficient distributed algorithms for deep reinforcement learning, by analyzing the statistics of neural networks through the lens of computation. The second is to design a scalable formal language for knowledge exchange and collaboration between intelligent machines, by using techniques from linked data and univalent foundations.
