Short Bio: 

Jennifer Barton received the BS and MS degrees in electrical engineering from the University of Texas at Austin and University of California, Irvine, respectively. She worked for McDonnell Douglas (now Boeing) on the Space Station program before returning to the University of Texas at Austin to obtain the Ph.D. in Biomedical Engineering in 1998. Since that time she has been an assistant and associate professor of Biomedical Engineering, Electrical and Computer Engineering, and Optical Sciences at the University of Arizona. She is Chair of the Biomedical Engineering Graduate Interdisciplinary Program and Director of the Arizona Research Labs Division of Biomedical Engineering.

Dr. Barton’s research interests include biomedical optical imaging and laser-tissue interaction. Her laboratory is host to an interdisciplinary mix of students and staff in the fields of engineering and optical, physical, and life sciences. Current research projects include: development of dual-modality optical coherence tomography (OCT) and laser-induced fluorescence (LIF) imaging systems with miniaturized delivery systems; use of these systems to visualize healing response to artificial implants; investigation of mechanisms of contrast and sensitivity of OCT-LIF to detect pre-cancers in humans and mouse models; and measuring the dynamic optical properties of photocoagulating blood.

Summary of Research Activity: 

 Dr. Barton has performed extensive research on laser-blood vessel interaction, helping develop a paradigm shift in cutaneous blood vessel treatment by exploiting time-varying optical properties of blood. A dual-wavelength laser system based on this work is now being utilized to treat resistant port wine stains. Jennifer is also developing optical coherence tomography and laser induced fluorescence as tools for drug and therapy development. Her group has designed and fabricated miniature and ultra-high resolution endoscopes that can visualize early stages of colon, ovarian, and skin cancer development in animal models and human patients.
