Michael R. Hamblin is a principal investigator at the Wellman Center for Photomedicine at Massachusetts General Hospital, Boston, and an associate professor of dermatology at Harvard Medical School and the Harvard-MIT Division of Health Science and Technology. His research interests lie in the areas of photodynamic therapy and low-level light therapy. He has published over 284 peer-reviewed articles and is a fellow of the SPIE.Marcelo Victor Pires de Sousa holds a bachelor’s degree and a PhD in physics. He is founder and chief science officer of Bright Photomedicine and is involved in the development of new products and dissemination of photomedicine.Tanupriya Agrawal obtained her MD in 2006 from Netaji Subhash Chandra Bose Government Medical College, Jabalpur, India, followed by a PhD in biomedical sciences from Creighton University, Omaha, Nebraska. She is a visiting postdoctoral fellow at Dr. Hamblin’s lab at the Wellman Center for Photomedicine, Massachusetts General Hospital. She is also an trainee pathology resident at Tufts Medical Center, Boston. Dr. Agrawal has published 11 peer-reviewed articles and 12 conference proceedings, including one oral presentation.

"The book presents exhaustive and timely coverage of low-power laser light therapy and photobiomodulation, a subject gaining increasing acceptance from the scientific and medical communities after years of controversial interpretations of clinical results. The editors have well-coordinated the fifty-four chapters written by experts from universities and hospitals. The book offers a panorama of the many applications reported so far, each of which is referenced within a vast bibliography."— Optics & Photonics News
