The Who's Who in Fluorescence 2005 is the 3r volume of the Who's who series. The previous two volumes (2003 and 2004) have been very well received indeed, with many copies being distributed around the world, through conferences and workshops, as well as through internet book sites. In the last 2 years a great many of you have sent comments and suggestions, we thank you all. We have tried to accommodate many of these into the new 2005 volume. This new 2005 volume features some 382 entries from no fewer than 32 countries, an increase from 312 entries in the 2003 volume. In addition, we have a continued strong company support, which will enable us to further disseminate the volume in 2005. In this regard we especially thank the instrumentation companies for their continued support, where without their finical contributions; it is likely that the volume would not be the success it is today. We have introduced a new author publication statistic into this volume, the Author Impact Measure (AIM) number. While voluntary, this number is intended to reflect an author's progress in past years. The AIM number simply summates the impact number (from the ISI database) of Journals published in, in that year, multiplied by the frequency of those publications. From those who chose to participate, we can see most impressive AIM numbers, in some instances, greater than 80 for an individual year.

Chris D. Geddes Ph.D., is an Associate Professor and Director of the Institute of Fluorescence, at the University of Maryland Biotechnology Institute, Medical Biotechnology Center in Baltimore, USA. He has a B.Sc. from Lancaster University in England and a Kodak funded Ph.D. in Physical Chemistry (fluorescence spectroscopy) from the University of Wales Swansea, UK. Dr Geddes is the Editor-in-Chief of the Journal of Fluorescence, and both the Editor and Founding editor of the Who's Who in Fluorescence and Annual Reviews in Fluorescence Volumes. He is also Executive Director of the Society of Fluorescence. Dr Geddes's research is based on the development and subsequent application of a wide variety of fluorescence based disciplines, such as multi-photon excitation, resonance energy transfer and more recently metal-enhanced fluorescence (also termed radiative decay engineering), to understanding biologically and industrially important systems and problems. The design, synthesis and characterization of new fluorophores and macromolecular protein-nanogold assemblies has recently led to the successful development of small molecule and sensing platforms for cyanide, TNT, glucose, fluoride and pH. Other research in Dr Geddes's Institute of Fluorescence involves developing non-invasive and continuous approaches for physiological glucose monitoring. Recently Dr Geddes has developed a range of highly-sensitive glucose sensing contact lenses that can monitor tear glucose levels ( 500 m), which track blood glucose levels which are 10-fold higher.Dr. J.R. Lakowicz is Professor of Biochemistry at the University of Maryland School of Medicine and Director of the Center for Fluorescence Spectroscopy. Dr. Lakowicz has published over 400 scientific articles, has edited numerous books, holds 16 issued patents, and is the sole author of the widely used text,Principles ofFluorescence Spectroscopy, also published by Kluwer Academic/Plenum Publishers, now in its Second Edition.
