Yoshinori Ohsumi is a Japanese cell biologist renowned for his groundbreaking research in the field of autophagy.
Life and Career
Yoshinori Ohsumi was born on February 9, 1945, in Fukuoka, Japan.
Yoshinori Ohsumi earned his bachelor’s degree in 1967 from the University of Tokyo, where he studied at the Faculty of Science. He then pursued his graduate studies at the same university, completing his Ph.D. in 1974.
After completing his doctorate, Ohsumi worked as a researcher at the Rockefeller University in New York City and the National Institute for Basic Biology in Japan. His research focused on the molecular mechanisms of protein transport within cells.
Ohsumi’s groundbreaking work on autophagy began in the 1990s when he used baker’s yeast as a model organism to identify the genes responsible for autophagy. His discoveries elucidated the complex molecular machinery underlying this cellular process, shedding light on its importance in maintaining cellular health. His research also extended to understanding the role of autophagy in various diseases, including cancer and neurodegenerative disorders.
