Krishna Persaud, PhD, FRSC, FInstMC, graduated with BSc Hons Biochemistry at the University of Newcastle-upon-Tyne, UK in 1976, MSc in Molecular Enzymology at the University of Warwick,UK, in 1977 and a PhD specialising in olfactory biochemistry in 1980. He subsequently worked at the University of Newcastle-upon-Tyne, University of Pisa and the Medical College of Virginia extending his knowledge in the Chemical Senses. He was appointed lecturer in Instrumentation and Analytical Science at UMIST, Manchester, UK in 1988, and progressed to his current position of Professor of Chemoreception at the University of Manchester, Department of Chemical Engineering and Analytical Science. He has been involved in research in chemoreception, crossing disciplines from biological aspects of olfaction to sensor arrays, electronics, signal processing and pattern recognition, and commercial development of artificial olfaction technologies. He has been involved in the development of gas sensor arrays for sensing odours based on conducting polymers that became commercialised by Aromascan plc, and is currently a director of Multisensor Systems Ltd. He has had a wide number of external activities such as Exchange Coordinator for the GOSPEL Network of Excellence, Committee member of the NOSE II forum, Executive secretary and Treasurer of the European Chemoreception Organisation (ECRO), and President of the International Society for Olfaction and Chemical Sensing (ISOCS). He has been an associate editor for a number of journals that include Materials Science and Engineering C, Biochemical Journal, IEEE Sensors Journal, Sensors and Actuators B. He has received a number of awards that include the Prince of Wales Award for Technological Innovation Certificate 1995, European Space Agency Certificate of Achievement in 1997, Silver Medal Royal Academy of Engineering, 1999, Water Industry Impact Award 2015. He has over two hundred and fifty publications in the field of chemical sensing.
