ANALYST, APRIL 1993, VOL. 118 Special Issue on 'Sensors & Signals' Guest Editors 315 Professor Malcolm R. Smyth PhD DSc CChem FRSC FICI University of London in 1976. He then studied as a Postdoc- toral Research Fellow at Colorado State University between 1976 and 1978, and was subsequently employed as a Visiting Research Scientist at the Nuclear Research Centre in Jiilich between 1979 and 1981. In 1981 he was appointed Lecturer in Analytical Chemistry at the (then) National Institute for Higher Education (NIHE) in Dublin (now Dublin City University). He became a Senior Lecturer in 1985 and took over as Head of the School of Chemical Sciences at Dublin City University in 1990. In 1990 he was awarded the degree of Doctor of Science (DSc) from The Queen's University of Belfast.In 1992 he was appointed Professor of Chemistry at Dublin City University. His research interests and experience are centred mainly in the fields of electroanalysis and chromatography. In particular, he is interested in the develop- ment of methods for the determination of substances of environmental or biological importance, with emphasis in the areas of microelectrodes, high-performance liquid chromato- graphy (HPLC) with electrochemical detection, inorganic applications of HPLC, electrochemical sensors and biosen- sors. He is the author/co-author of over 100 publications, and has edited three books. He is currently a member of the Editorial Board of The Analyst and serves on the Editorial Advisory Board of Analytical Letters, Talanta, Electroanaly- sis, Journal of Pharmaceutical and Biomedical Analysis, Analytical Chimica Acta and Encyclopaedia of Analytical Science.He is a Fellow of both The Royal Society of Chemistry and the institute of Chemistry of Ireland. Professor Malcolm R. Smyth obtained his Bachelors degree in Biochemistry from The Queen's University of Belfast in 1972 and his Ph.D. in Analytical Chemistry at Chelsea College, Dr. Dermot Diamond BSc MSc PhD CChem MRSC MICI Dr. Dermqt Diamond obtained his BSc in 1976 from The Queen's University of Belfast where he also obtained his MSc and PhD under the supervision of Professor Gyula Svehla on the development of novel ion-selective electrodes. He then moved to Dublin City University in 1987 and is now Senior Lecturer in the School of Chemical Sciences. He is a member of The Royal Society of Chemistry and a member of the Institute of Chemistry of Ireland. In addition, he has also served on several organizing committees for The Royal Society of Chemistry Annual Chemical Congress. His research interests include chemical sensors, sensor arrays and signal processing, computer-based data acquisition and control, virtual instruments and supramolecular chem- istry. He has over 30 publications in these areas to his credit.
