Krishna C. Persaud, FRSC, FInstMC, graduated with a BSc Honors degree in biochemistry from the University of Newcastle-upon-Tyne, UK, in 1976 and then graduated with an MSc in molecular enzymology from the University of Warwick, UK, in 1977 and a PhD specializing 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. Dr. Persaud was appointed lecturer in instrumentation and analytical science at University of Manchester Institute of Science and Technology, Manchester, UK, in 1988, and progressed to his current position of professor of chemoreception in the School of Chemical Engineering and Analytical Science at the University of Manchester. He has been involved in research of chemoreception, crossing disciplines from biological aspects of olfaction to sensor arrays, electronics, signal processing and pattern recognition, and commercial development of artificial olfaction technologies.

Santiago Marco completed his licenciatura degree in applied physics in 1988 and received a PhD in microsystem technology from the University of Barcelona in 1993. He held a European Human Capital Mobility grant for a postdoctoral position in the Department of Electronic Engineering at the University of Rome “Tor Vergata.” Since 1995, he has been an associate professor of electronic instrumentation in the Department of Electronics at the University of Barcelona. In 2004 Dr. Marco spent a sabbatical leave at EADS Corporate Research, Munich, to work on ion mobility spectrometry. In 2008 he was appointed leader of the Artificial Olfaction Lab at the Institute of Bioengineering of Catalonia. Dr. Marco’s research concerns the development of signal/data processing algorithmic solutions for smart chemical sensing based in sensor arrays or microspectrometers integrated typically using microsystem technologies.

Agustín Gutiérrez-Gálvez received his BE degrees in physics and electrical engineering from the University of Barcelona in 1995 and 2000, respectively. He received his PhD degree in computer science from Texas A&M University in 2005. In 2006 Dr. Gutiérrez-Gálvez was a JSPS postdoctoral fellow at Tokyo Institute of Technology and came back to the University of Barcelona with a Marie Curie fellowship. Currently, he is an assistant professor in the Department of Electronics at the University of Barcelona. His research interests include biologically inspired processing for gas sensor arrays, computational models of the olfactory system, pattern recognition, and dynamical systems.
