Research
Wilder-Smith's research focuses on noninvasive optical techniques such as fluorescence and optical coherence tomography and their use in the diagnosis of oral cancer. She is particularly concerned with developing technologies for the early detection of precancerous and cancerous tissues in the mouth. She has collaborated with researchers at the City of Hope, UCLA, the University of Pennsylvania and elsewhere, publishing more than 100 publications in over 20 years. She has received funding from the National Institutes of Health, the United States Department of Defense, and others.
Wilder-Smith is working with Dr. Zhongping Chen at the University of California, Irvine, Dr Rongguang Liang at the University of Arizona's College of Optical Sciences, and Dr. M. A. Kuriakose at the Mazumdar-Shaw Cancer Center in Bangalore, India to develop an inexpensive portable device for detection of oral cancer, which accounts for 35% of cancer deaths among Indian men. The solar-powered device, slightly larger than a shoebox, uses mobile phone technology to send laser images of oral lesions to specialists for assessment.
Wilder-Smith serves on advisory boards of the American Society for Laser Medicine and Surgery, the Diagnostic Sciences Group of the International Association for Dental Research and the Prevent Cancer Foundation. She serves on the editorial boards of the Journal of Photomedicine and Laser Surgery, the Journal of Biomedical Optics and the journal Lasers in Surgery and Medicine.
