William J. Schwartz, M.D., practices general neurology and is involved in the mentoring of trainees in basic and clinical neuroscience.

For nearly four decades, he has conducted NIH-funded research on biological clocks and especially on the “master” brain clock in the mammalian hypothalamus. He was elected chair of the Gordon Conference on Chronobiology (1993), president of the Society for Research on Biological Rhythms (SRBR) (2004-2006) and editor-in-chief of the Journal of Biological Rhythms (2014-2019). He delivered the plenary lecture of the founding congress of the Japanese Society of Chronobiology (1994), the 9th Pittendrigh/Aschoff Lecture of the SRBR (2014) and the 5th J. Ariëns Kappers Lecture of the European Biological Rhythms Society (2017). At Dell Med, he is working on the development of interdisciplinary courses at the intersection of biology and medicine for UT undergraduates and the approach to patients with neurological disease for Dell Med students and residents. In 2020, he was inducted as a member of the Dell Med Academy of Distinguished Educators, and in 2022, he was inducted as a member of the UT System Kenneth I. Shine, M.D., Academy of Health Science Education.

After completing his medical degree and neurology residency at the University of California, San Francisco, and a research fellowship at the National Institute of Mental Health, he served on the faculties of Harvard Medical School, Massachusetts General Hospital and the University of Massachusetts before his current position. Since 2005, he has been awarded invited professorships for terms at universities in the Netherlands, France, Germany, Italy, Israel, New Zealand, Japan and the United States.
