, one of the subjects in the longitudinal research on exceptionally gifted children by education researcher Miraca Gross
. His father told the press that at the age of two, during a family gathering, Tao attempted to teach a 5-year-old child mathematics
and English
. According to Smithsonian Online Magazine, Tao could carry out basic arithmetic by the age of two. When asked by his father how he knew numbers and letters, he said he learned them from Sesame Street
. Aside from English, Tao speaks Cantonese, but does not write Chinese
.
When he was 24, he was promoted to full professor at UCLA and remains the youngest person ever appointed to that rank by the institution. Tao's father was born and grew up in Shanghai
, and Tao's mother is Cantonese
by ethnicity. His parents are first generation immigrants from Hong Kong
to Australia
. His father, Billy Tao is a pediatrician, and his mother is a physics and mathematics graduate from the University of Hong Kong, formerly a secondary school teacher of mathematics
in Hong Kong
.
Tao has two brothers living in Australia, both of whom represented Australia at the International Mathematical Olympiad
.
Tao currently lives with his wife Laura, son, and daughter in Los Angeles
, California
.
Tao exhibited extraordinary mathematical abilities from an early age, attending university level mathematics courses at the age of nine. He is one of only two children (besides Lenhard Ng
) in the history of the Johns Hopkins' Study of Exceptional Talent
program to have achieved a score of 700 or greater on the SAT math section while just 8 years old (he scored a 760). In 1986, 1987, and 1988, Tao was the youngest participant to date in the International Mathematical Olympiad
, first competing at the age of ten, winning a bronze, silver, and gold medal respectively. He won the gold medal when he just turned thirteen and remains the youngest gold medallist in the Olympiad's history. At age 14, Tao attended the Research Science Institute
. When he was 15 he published his first assistant paper. He received his bachelor's and master's degrees (at the age of 17) from Flinders University
under Garth Gaudry. In 1992 he won a Fulbright Scholarship to undertake postgraduate study in the United States
. From 1992 to 1996, Tao was a graduate student at Princeton University
under the direction of Elias Stein, receiving his Ph.D.
at the age of 20. He joined the faculty of the University of California, Los Angeles
in 1996.
, widely considered the top honour a mathematician can receive. In September 2006, he was awarded a MacArthur Fellowship. He was elected a Fellow of the Royal Society on 18 May 2007. He became a foreign associate of the United States National Academy of Sciences
in 2008 and elected a Fellow of the American Academy of Arts and Sciences
in 2009. On 11 January 2010, the King Faisal Foundation
announced that Tao is the co-winner of the King Faisal International Prize in the field of science for his works in mathematics.
He received the Salem Prize
in 2000, the Bôcher Prize in 2002, and the Clay Research Award
in 2003, for his contributions to analysis including work on the Kakeya conjecture and wave maps. In 2005 he received the American Mathematical Society
's Levi L. Conant Prize with Allen Knutson, and in 2006 he was awarded the SASTRA Ramanujan Prize
.
In 2004, Ben Green
and Tao released a preprint proving what is now known as the Green–Tao theorem. This theorem states that there are arbitrarily long arithmetic progression
s of prime number
s. The New York Times
described it this way: For this and other work, he was awarded the Australian Mathematical Society Medal
in 2005.
In 2006, at the 25th International Congress of Mathematicians
in Madrid
, he became one of the youngest, the first Australian, and the first UCLA faculty member ever to be awarded a Fields Medal
. An article by New Scientist
writes of his ability:
Tao was a finalist to become Australian of the Year
in 2007. He is a corresponding member of the Australian Academy of Science
, and in 2007 was elected as a Fellow of the Royal Society. In the same year Tao also published Tao's inequality, an extension to the Szemerédi regularity lemma
in the field of information theory
.
In April 2008, Tao received the Alan T. Waterman Award
, which recognizes an early career scientist for outstanding contributions in their field. In addition to a medal, Waterman awardees also receive a $500,000 grant for advanced research.
In December 2008, he was named The Lars Onsager
lecturer of 2008, for "his combination of mathematical depth, width and volume in a manner unprecedented in contemporary mathematics". He was presented the Onsager Medal, and held his Lars Onsager lecture entitled "Structure and randomness in the prime numbers" at NTNU
, Norway
.
In 2010, he received the King Faisal International Prize jointly with Enrico Bombieri
. Also in 2010, he was awarded the Nemmers Prize in Mathematics
along with the Polya Prize(SIAM)
. Tao and Van H. Vu
solved the circular law
conjecture.
In 2011, he was one of the many to be nominated as Australian of the Year
. However, he did not win.
As of 2007 Tao has published over 140 research papers and has won 13 different awards.
