ASCI Scientific Sessions: Masashi Yanagisawa, MD, PhD

The American Society for Clinical Investigation is proud to present the ASCI Scientific Sessions: a monthly spotlight on distinguished investigators and their contributions to biomedical research. The Scientific Sessions are free and open to all, with a goal to create a space for our community, beyond the ASCI’s annual meeting, to gather and celebrate discovery.

Masashi Yanagisawa, MD, PhD, is Director of the International Institute for Integrative Sleep Medicine at the University of Tsukuba.

As a graduate student at University of Tsukuba, Dr. Yanagisawa discovered endothelin, a potent vasoconstrictor peptide from vascular endothelial cells. After moving to the University of Texas Southwestern Medical Center at Dallas, he discovered that orexin deficiency causes the sleep disorder narcolepsy, opening a new avenue in sleep research which led to a better understanding of sleep/wake switching mechanisms in the brain. Recognizing that the fundamental mechanism for sleep homeostasis remains a mystery, in 2010 he embarked upon a highly ambitious project of polysomnography (EEG/EMG)-based forward genetic screen for sleep/wake abnormalities in chemically mutagenized mice, which has recently led to identification of several new genes that are important to the regulation of sleep amounts and the level of sleep need.

An elected member of the National Academy of Sciences and the ASCI, Dr. Yanagisawa is the recipient of many honors, including The Asahi Prize and The Keio Medical Science Prize (2018). He was named a Person of Cultural Merit by the Government of Japan (2019) and received the Breakthrough Prize in Life Sciences (2023).

​​This event will be moderated by Benjamin D. Humphreys, MD, PhD, 2023-2024 ASCI President, Chief of the Division of Nephrology and the Joseph Friedman Professor at Washington University in St. Louis, and member of the Board of Scientific Counselors for the National Institute of Diabetes and Digestive and Kidney Diseases.
