Research Interests
Troy Lee joined the Division of Mathematical Sciences (School of Physical and Mathematical Sciences) in September 2013. He received his Bachelors degree with honors in mathematics from the California Institute of Technology in 2000. From there, he went to the University of Amsterdam, for both Masters (2001) and PhD (2006) degrees, writing a thesis on Kolmogorov Complexity and Formula Size Lower Bounds. He won a Rubicon Fellowship from the Netherlands Science Foundation to do a Postdoc at University of Orsay, Paris. Then he spent two years as a postdoc at Rutgers University with a National Science Foundation Research Fellowhip, and one year at Columbia University. In 2010 he joined the Centre for Quantum Technologies as a Senior Research Fellow and has a joint appointment with NTU and CQT. In 2013 he was awarded a NRF fellowship.
