About Barbara Henderson


Dr. Barbara W. Henderson earned her doctoral degree in Zoology at the University of Graz, Austria, in 1966 and joined the staff of Roswell Park Comprehensive Cancer Center (Roswell Park) in 1970, as a Cancer Research Scientist. Dr. Henderson was the Program Leader, Biophysical Therapies Program, and the first Chair of the Department of Cell Stress Biology. She retired from these positions in 2015 as the Director of the Photodynamic Therapy Center.

Dr. Henderson's laboratory research has provided numerous seminal insights into the mechanisms and strategies for optimization of photodynamic therapy (PDT); oxygen and light dependency of PDT; the effect of PDT on the host immune response against tumor; and determinants of photodynamic tumor destruction.

Dr. Henderson was a member of the American Association for Cancer Research, American Society of Photobiology, International Photodynamic Association, and the Radiation Research Society. She had for many years served as Associate Editor of the journal Photochemistry and Photobiology. She is a past member of the NCI Radiation Study Section and Subcommittee D (Clinical Studies) of the NCI Initial Review Group. She was a member of numerous committees at Roswell Park and had authored or co-authored more than 80 journal publications, book chapters and abstracts.
