Seminar - Skin optics: the connection between intrinsic properties of skin and the appearance of skin

#yp #postgraduate #wie #nz #central #section #seminar #Skin #optics

Optical images and spectroscopy of skin can characterize the appearance of skin... the sheen, the glow, the smoothness, the pigmentation. Such parameters are worthwhile to assess, and of practical use to people managing their skin's appearance. Such observed parameters are connected to the intrinsic properties of skin: blood content, oxygen saturation of hemoglobin in blood, water content, melanin content, scattering properties, as well as the architecture of skin (depth of the blood, multiple layers: epidermis, papillary dermis, vascular plexus, reticular dermis, fat, muscle). The geometry of observation (delivery and collection of light from the skin) influences how intrinsic properties map to observed parameters. This talk will discuss how light transports in/through/out of skin based on skin properties and architecture, and yields the observed appearance of skin.

Steven L. Jacques, Ph.D., received a B.S. degree in Biology at M.I.T., and an M.S. degree in Electrical Engineering and Computer Science and a Ph.D. degree in Biophysics and Medical Physics from the University of California-Berkeley. In 1983, he joined the Wellman Laboratory for Photomedicine at Mass. General Hospital (Lecturer, Harvard Medical School). In 1988, he joined the University of Texas M. D. Anderson Cancer (tenured Assoc. Professor of Urology/ Biophysics). In 1996, he joined Oregon Health & Science University as Professor of Biomedical Engineering & Dermatology. In 2019, he joined Bioengineering at the University of Washington, Seattle. In 2020, he was awarded the Britton Chance Award for “pioneering work in the field of biomedical op]cs.” The Jacques Lab develops novel optical technologies for diagnostic and surgical/therapeutic applications for biomedical research and medical care. Current projects include polarized light imaging that is sensitive to the nano-, micro- and meso-scale structure of tissues (bedside pathology), and spectral camera imaging of blood perfusion and oxygen utilization in microvasculature of skin.
