Tadashi Tokieda

Tadashi Tokieda (Japanese: 時枝正) is a Japanese mathematician, working in mathematical physics. He is a professor of mathematics at Stanford University;[3] previously he was the Director of Studies in Mathematics[4] at Trinity Hall, Cambridge. He is also very active in inventing, collecting, and studying toys that uniquely reveal and explore real-world surprises of mathematics and physics.[5] In comparison with most mathematicians, he had an unusual path in life: he started as a painter, and then became a classical philologist, before switching to mathematics.[6]

Life and career

Tokieda was born in Japan and grew up to be a painter.

He then studied at Lycée Sainte-Marie Grand Lebrun[1] in France as a classical philologist. According to his personal homepage, he taught himself basic mathematics from Russian collections of problems.

He is a 1989 classics graduate from Sophia University[1] in Tokyo and has a 1991 bachelor's degree from Oxford in mathematics (where he studied as a British Council Fellow). He obtained his PhD at Princeton under the supervision of William Browder.[7]

Tokieda joined the University of Illinois at Urbana Champaign as a J. L. Doob Research Assistant Professor for the 1997 academic year.[8]

He has been involved in the African Institute for Mathematical Sciences since its beginning in 2003.

In 2004 he was elected a Fellow of Trinity Hall, where he became the Director of Studies in Mathematics and the Stephan and Thomas Körner Fellow.[9][10]

He was the William and Flora Hewlett Foundation Fellow in 2013–2014 at the Radcliffe Institute for Advanced Study at Harvard University.[11]

In the academic year 2015–2016 he was the Poincaré Distinguished Visiting Professor at Stanford.[12]

He is fluent in Japanese, French, and English and knows ancient Greek, Latin, classical Chinese, Finnish, Spanish, and Russian.[6] So far he has lived in eight countries.[13]

In March 2020, Tokieda was interviewed on The Joy of X, Steven Strogatz's podcast for Quanta Magazine.[14]
