Tze-Chien Sum is an Associate Professor at the Division of Physics and Applied Physics, Nanyang Technological University (NTU), where he leads the Femtosecond Dynamics Laboratory. He received his Ph.D. in 2005 from the National University of Singapore (NUS). His research focuses on investigating light matter interactions; energy and charge transfer mechanisms; and probing carrier and quasi-particle dynamics in a broad range of emergent nanoscale and light harvesting systems. Dr Sum received a total of 11 teaching awards from NUS and NTU, including the coveted Nanyang Award for Excellence in Teaching in 2006 and the 2010 SPMS Teaching Excellence Honour Roll Award. Most recently, he received the 2013 SPMS Young Researcher Award; the Institute of Physics Singapore 2014 World Scientific Medal and Prize for Outstanding Physics Research; and the 2014 Nanyang Award for Research Excellence. Nripan Mathews is an Assistant Professor at the School of Materials Engineering in Nanyang Technological University. He pursued his Ph D at a joint laboratory of molecular crystals in a collaboration with Commissariat à l”énergie atomique (CEA), Centre national de la recherche scientifique (CNRS) and Université de Pierre et Marie Curie (Paris VI University). He was also a visiting scientist at Prof. Michael Graetzel”s laboratory at École Polytechnique Fédérale de Lausanne (EPFL), working on a pan-European project on photoelectrochemical hydrogen production. His research focuses on a wide variety of novel materials (metal oxides, organic semiconductors, graphene, carbon nanotubes, sulfides and selenides) and novel morphologies (one dimensional structures such as nanowires and nanotubes, thin films as well as two dimensional nanosheets) produced through a range of fabrication procedures. He has focused primarily on the electronic and optical properties of these materials and how they can be adapted for practical applications.
