| Stephen J. Gardiner is Professor of Mathematics at UCD. His research interests are in potential theory, function theory and approximation by harmonic functions. He is author of about 90 scientific publications in leading journals and books and has written the research monograph Harmonic Approximation (Cambridge University Press, 1995). His second book, Classical Potential Theory, written jointly with Professor David Armitage of Queen's University Belfast, is in the Springer Monographs in Mathematics Series (352pp., Springer, London, 2001). In 1995 he was awarded the degree of Doctor of Science by Queen's University on the basis of published research, and in 2000 he was elected a Member of the Royal Irish Academy. He spent the year 1992 on sabbatical leave at McGill University, Montreal, and visited Charles University, Prague for the autumn term in 2005. Other assignments outside the university include lecture series in Sweden (1996), Japan (1997), the Czech Republic (1998), Canada (2000), Russia (2001) and Hungary (2009), and collaborative research projects at the Oberwolfach Mathematical Research Institute (1995, 1997, 1999) and the Mittag-Leffler Institute (1999). Other awards include a UCD President's Research Fellowship (2005/06), and an Erskine Fellowship at the University of Canterbury, New Zealand (2006). He was the Irish co-ordinator of the European Union Research Training Network 'Classical Analysis, Operator Theory, Geometry of Banach Spaces, their Interplay and Applications' (2000-2004) and Principal Investigator of the Science Foundation Ireland (SFI) project 'Potential theory and quadrature domains' (2006-2010). Currently he is the Principal Investigator of the Research Frontiers project 'Universality, approximation and potential theory' (2009-2013), funded by SFI, and is a member of the Steering Committee of the European Science Foundation Research Network 'Harmonic and Complex Analysis and its Applications' (2007-2012). He served from 2001-2010 as an Editorial Adviser for the Proceedings, Journal and Bulletin of the London Mathematical Society and is at present an Editorial Board member of the Springer journal Potential Analysis. |
