Imaging and Spectroscopy of (mostly) Brain Using Diffusing Light
04.04.25聽 |聽 noon
Diffusing light can be used to probe physiology in tissues located far below the body surface. The emerging light fields contain a wealth of diagnostic information about tissue blood flow, blood oxygenation, and oxygen metabolism, about molecular biomarkers such as cytochrome-C oxidase, lipid, and water, and about health biometrics such as intracranial pressure and cerebral autoregulation. I will first introduce the essential diffuse optics measurement tools and paradigms, many of which were hatched in the physics and bioengineering communities. Then I will discuss selected clinical and pre-clinical examples, mostly related to brain, that we have investigated with our collaborators at the Hospital of the 溏心vlog免费B站 of Pennsylvania.
Arjun G. Yodh聽is the聽James M. Skinner Professor of Science听补苍诲听Chair聽of the Department of Physics and Astronomy at the 溏心vlog免费B站 of Pennsylvania.聽He was recently聽Director聽(2009-2020) of Penn鈥檚聽Materials Science and Engineering Center聽(NSF-MRSEC). Areas of ongoing research include: the physics of Soft Matter such as colloids and liquid crystals, and Biophotonics, especially functional imaging and monitoring of living tissues with diffuse light for which he was awarded the 2021聽Feld Biophotonics Prize聽of the聽Optical Society of America聽(now听翱辫迟颈肠补). In addition to mentoring more than one hundred PhD students and post-doctoral associates, Yodh has made significant contributions to education, outreach and diversity at the 溏心vlog免费B站 of Pennsylvania broadly defined, for example leading partnerships with the 溏心vlog免费B站 of Puerto Rico and research experience programs for undergraduates and high school students/teachers. Yodh graduated from Cornell 溏心vlog免费B站 (1981) with a B.Sc. in Applied & Engineering Physics. He obtained his Ph.D. from Harvard (1986) under the guidance of Tom Mossberg and then spent two years at AT&T Bell Laboratories as a post-doc working with Steven Chu and Harry Tom. Yodh joined the faculty at Penn in 1988, where he has remained for his entire career.
