Lloyd Davis is BH Goethert Professor of Physics at the University of Tennessee Space Institute (UTSI), a graduate campus of the University of Tennessee Knoxville. Lloyd is currently involved in projects in nanophotonics, biotechnology, single-molecule spectroscopy, micro/nano-fluidics and femtosecond laser materials processing. Lloyd received a PhD in physics from the University of Auckland, New Zealand. At UTSI, he has taught over 75 graduate-level courses in physics and has served as major advisor to 19 MS and PhD graduates specializing mostly in optical physics and as mentor to 7 postdoctoral staff. Lloyd spent several summers at Los Alamos National Laboratory, where he received an R&D 100 award for early work on single-molecule detection in solution. He subsequently conducted other pioneering work on single-molecule spectroscopy at Los Alamos and at UTSI. He also performed research at Oak Ridge National Laboratory (ORNL), including some of the first experiments on single-molecule spectroscopy within microfluidic devices. Since 2006, he has been a user at the Center for Nanophase Materials Sciences at ORNL. Since 2007 he has been an external associate at the Vanderbilt Institute for Integrative Biosystems Research and Education (VIIBRE). From August to December, 2010, he was a visiting Fellow at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado, Boulder. From January to May, 2011, he was a Visiting Researcher with The Photon Factory at Auckland University, New Zealand. Lloyd has been a member of the Optical Society of America since 1985 (senior member, 2009), SPIE since 1987 (senior member, 2011), the Biophysical Society since 2001, and the American Physical Society since 2007. He has served as reviewer for a number of journals for the above professional societies, as well as the American Chemical Society and others, and as a reviewer for funding agencies in the USA and other countries.
