Assistant Professor David Smith received his Master’s degree in Mathematics from University of York, United Kingdom, in 2007 and his PhD from University of Reading in 2011. Before joining Yale-NUS College in 2016, he held postdoctoral fellowships at University of Michigan, University of Cincinnati and University of Crete.
