Joan Miller (née Whitten) was born in Toronto, Canada, and attended Bishop Strachan School. [1] She received her SB in biology from Massachusetts Institute of Technology, where she also rowed crew for four years, taking 2nd place in the Head of the Charles Regatta in 1978 and 3rd nationally in 1980.

Photodynamic therapy (PDT) is a form of phototherapy involving light and a photosensitizing chemical substance used in conjunction with molecular oxygen to elicit cell death (phototoxicity). [ 1 ] PDT is used in treating acne , wet age-related macular degeneration , psoriasis , and herpes .
Schematic representation of the mechanism of (a) photopharmacology (b) photodynamic therapy, and (c) optogenetics. The discovery of natural photoreceptors such as rhodopsins in the eye inspired the biomedical and pharmacology research community to engineer light-sensitive proteins for therapeutic applications.

Dental infections tend to also respond better to photothermal therapy than photodynamic therapy, though both have a strong effect. [ 10 ] [ 11 ] [ 12 ] The efficacy of PDT for antimicrobial usage is limited by the properties of the membrane of the target cell such as the electrical gradient ( membrane potential ) and lipid composition.
Macular degeneration is an incurable eye disease in which the central portion of the retina, the macula, deteriorates. The macula focuses your central vision, which is important for fine detail ...
Between 1996 and 1998, he was a senior associate research scientist at Kellogg Eye Center and the Center for Ultrafast Optical Sciences at the University of Michigan, Ann Arbor. From 1998 to 2004, he served as an associate professor in the Department of Biomedical Engineering and Kellogg Eye Center at the University of Michigan. Since 2004, he ...
Laser radiation being delivered via a fiber for photodynamic therapy to treat cancer. A 40-watt CO 2 laser with applications in ENT, gynecology, dermatology, oral surgery, and podiatry. Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, [1] photorejuvenation, and laser surgery.
The efficacy of antimicrobial photodynamic therapy, using various distinct photosensitizers, has been studied since the 1990s. [ 9 ] [ 7 ] Most studies have yielded positive outcomes, often achieving disinfection levels, as defined by infection control guidelines, exceeding 5 log 10 (99.999%) of microbial inactivation. [ 14 ]
