## Academics

Matsumoto was born and raised in Honolulu, Hawaii. He received his B.A. from the University of Michigan at Ann Arbor in 1981 with high honors in psychology and Japanese. Matsumoto proceeded to obtain his master's degree and doctorate degrees in psychology from the University of California at Berkeley in 1983 and 1986, respectively.
Since 1989, Matsumoto has been a professor of psychology at San Francisco State University, where he received a distinguished faculty award in 2009.
He is also the founder and director of the Culture and Emotion Research Laboratory (CERL) at San Francisco State.
In January 2009, Matsumoto received a $1.9 million Minerva Award research grant from the US Department of Defense to examine the role of emotions in ideologically based groups.
Most recently in 2018 Matsumoto was San Francisco State University's nominee for the Jefferson Award for Public Service. This award recognizes people who make a difference on a daily basis in their local communities without expectation of reward.

## Psychology

Matsumoto has collaborated with many other psychologists, including Dr. Paul Ekman and Dr. Mark Frank, both acclaimed psychologists in the study of facial expressions and emotions.
In addition to conducting extensive research, Matsumoto, Ekman and Frank created the Microexpression Training Tool (METT1), the first training tool developed to improve one's ability to read microexpressions. Ekman and Matsumoto then proceeded to create a proceeding version of the training tool, METT2.
Both Matsumoto and Ekman now have their own versions of the microexpression training tool, which is available on their websites.
In 2009, Matsumoto and Bob Willingham conducted a study examining spontaneous facial expressions in blind judo athletes. They discovered that many facial expressions are innate and not visually learned.
Matsumoto says that "Spontaneously produced facial expressions of emotion of both congenitally and non-congenitally blind individuals are the same as for sighted individuals in the same emotionally evocative situations. We also see that blind athletes manage their expressions in social situations the same way sighted athletes do."
Their study received much publicity and critical acclaim, including coverage in Time magazine and on CNN.
