Zinovy B. Reichstein (born 1961) is a Russian-born American mathematician. He is a professor at the University of British Columbia in Vancouver. He studies mainly algebra, algebraic geometry and algebraic groups. He introduced (with Joe P. Buhler) the concept of essential dimension.[1]

Early life and education

[edit]

In high school, Reichstein participated in the national mathematics olympiad in Russia and was the third highest scorer in 1977 and second highest scorer in 1978.

Because of the Antisemitism in the Soviet Union at the time, Reichstein was not accepted to Moscow University, even though he had passed the special math entrance exams. He attended a semester of college at Russian University of Transport instead.

His family then decided to emigrate, arriving in Vienna, Austria, in August 1979 and New York, United States in the fall of 1980. Reichstein worked as a delivery boy for a short period of time in New York. He was then accepted to and attended California Institute of Technology for his undergraduate studies.[2]

Reichstein received his PhD degree in 1988 from Harvard University under the supervision of Michael Artin. Parts of his thesis entitled "The Behavior of Stability under Equivariant Maps" were published in the journal Inventiones Mathematicae.[3]

Career

[edit]

As of 2011, Reichstein is on the editorial board of the mathematics journal Transformation groups.[4]

After graduating from Harvard, Reichstein joined the University of Pennsylvania. In 1992, he began working at the University of California, Berkeley. The following year, he moved to Oregon State University. In 2001, Reichstein accepted a position at the University of British Columbia.[5]
