About
Dr Chris D. Geddes, Ph.D., Professor, has extensive experience in fluorescence spectroscopy, particularly in fluorescence sensing and metal-fluorophore interactions, publishing over 350 peer-reviewed papers (h-index: 57), and 35 books. Dr Geddes is internationally known in fluorescence and plasmonics and his laboratory is widely attributed to the development of the Metal-Enhanced Fluorescence (MEF) and related plasmon-fluorescence technologies, securing in excess of $25 million in recent years to persue his research aspirations. He is the editor-in-chief of the Journal of Fluorescence and founding editor-in-chief of the Who’s Who in Fluorescence, Annual Reviews in Fluorescence and the Annual Reviews in Plasmonics volumes. In addition, due to the labs’ pioneering efforts in the fields of metallic nanoparticle-fluorophore interactions, Dr Geddes launched a Springer Journal “Plasmonics” in 2005, which has had an impact factor ~ 4. Dr Geddes is Director of the Institute of Fluorescence, a department within UMBC (University of Maryland Baltimore County), which focuses on the nano-bio-technological applications of fluorescence. Dr Geddes was a permanent member of the NIH’s EBIT R01 study section and chaired the NIH’s Analytical and BioAnalytical SBIR study section from ~ 2004-2009. Dr Geddes is a fellow of both the Royal Society of Chemistry and the Institute of Physics. Dr Geddes holds ≈ 100 patents in the fields of fluorescence and plasmonics.
