Michael S. Feld (November 11, 1940 – April 10, 2010) was an American physicist, who was best known for his work on quantum optics, and medical applications of lasers.
Michael S. Feld received his Ph.D. from the Massachusetts Institute of Technology under the supervision of laser pioneer Ali Javan.
In the later part of his career, he turned his attention to the field of biomedical optics, where he developed methods for in-tissue spectroscopy and imaging.
Feld also directed the Laser Biomedical Research Center at MIT, where he worked on fluorescence and Raman spectroscopy to measure in-vivo levels of biomarker molecules that assisted in the imaging of disease-causing microorganisms via endoscopy and optical tomography.
Feld strongly valued a scientific environment without ethnic or cultural prejudice, and many of his co-workers and Ph.D. students were from minority groups.
