Biography
Dr. Toh obtained his Bachelor of Science (Direct Hons) and Masters of Science at the National University of Singapore. He subsequently further his graduate studies at the University of Southampton, U.K., working with Phil Bartlett on electrochemical biosensors. Thereafter, he continued his postdoctoral work at the California Institute of Technology with Nathan Lewis on nanostructured materials. He was Senior Tutor, Research Fellow and Assistant Professor with NUS before joining NTU in 2010. His other professional experiences are: Co-organizer, Recent Advances in Electrochemcial INstrumentation and Electrodes, 63rd Annual Meeting of the International Society of Electrochemistry, Aug 19-24, Nice France (2010); Regional Organizing Committee member, 2nd Regional Electrochemistry Meeting of South-East Asia, Thailand, 16-19 Nov (2010); Co-organizer, Environment, Water and Analytical Electrochemistry, 61st Annual Meeting of the International Society of Electrochemistry, Sep 26-Oct 1, Nice France (2010); Editor, Malaysian Journal of Chemistry, Special Issue, AsiaAnalysis Conference (2009); Vice-Chair, Division 1: Analytical Electrochemistry, International Society of Electrochemistry (2009- ); Founding Chair, 1st Regional Electrochemistry Meeting of South-East Asia, Singapore, 5-7 Aug (2008); Member, Engell Prize Award Committee, International Society of Electrochemistry; Co-Chair, Analytical, Environment and Green Chemistry, Singapore International Chemical Conference-5, Singapore, 17-19 December (2007); Reviewer for Talanta, Bioinspiration & Biomimetics, Electrochimica Acta, Surface and Interface analysis, Journal of Electroanalytical Chemistry, Electroanalysis, Journal of Chemical Education, Surface and Interface analysis; Malaysian Journal of Chemistry; Honorary Treasurer, Singapore National Institute of Chemistry (2005-2007); Guest Editor, Electrochimica Acta, Special Issue, ISE Spring Meeting (2006); Chair, Local Organizing Committee, International Society of Electrochemistry Spring Meeting, Singapore,17-20 April (2006)
Research Interests
His general interest is analytical chemistry and his current research interests are in the developments of biosensors using new ultrasensitive methods for direct detection of virus through specific interaction of envelope proteins with antibodies. His group is also interested in the development of new methods for ultrasensitive detection and identification of specific gene sequences. Presently, he is working actively on development of diagnostic tools for dengue and other microbes. His method using similar approach was useful for detection of water pollutants of environmental concerns. His other research interest is the study of ion transport through nanosized channels and the utilization in energy efficient biomimetic applications.
