Henry Tye
Encyclopedia
Sze-Hoi Henry Tye (born 1948 in Hong Kong
) is a Chinese-American cosmologist and theoretical physicist
most notable for proposing that a brane and an antibrane attraction and annihilation with one another, causes cosmic inflation
and his work on superstring theory
, brane cosmology
and elementary particle physics. He received his B.S.
from the California Institute of Technology
and his Ph.D.
in physics
from the Massachusetts Institute of Technology
under Francis Low. He is currently the Horace White Professor of Physics at Cornell University
and a fellow of the American Physical Society
. He has also recently become the director of the Institute for Advanced Study within the Hong Kong University of Science and Technology .
Together with Gia Dvali
, he suggested the idea of brane inflation in 1998 which was later put on concrete string theoretic grounds by Shamit Kachru and collaborators. He went on to work out many details of brane inflation with his research group at Cornell. He was responsible for the revival of the interest in cosmic strings. Cosmic superstrings are produced at the end of brane inflation due to brane-antibrane annihilation. Apart from the details of brane inflation, he has been working on issues related to the string landscape and quantum cosmology with his collaborators.
Alan Guth
, in his book The Inflationary Universe, tells the story of how he was led to think about issues that resulted in the original idea of cosmic inflation due to the influence of Henry Tye. At that time they were both postdocs at Cornell University
.
Earlier on in his career Tye was involved with many important ideas such as the construction of fermionic string models with Kawai and Lewellen (Kawai-Lewellen-Tye), fractional superstrings, grand unified string models, brane world.
Tye was appointed the Director of Institute of Advanced Study, Hong Kong University of Science & Technology, in 2011. Prior to this he was the Horace White Professor of Physics at Cornell University.

Physicist
A physicist is a scientist who studies or practices physics. Physicists study a wide range of physical phenomena in many branches of physics spanning all length scales: from sub-atomic particles of which all ordinary matter is made to the behavior of the material Universe as a whole...

Cosmic inflation
In physical cosmology, cosmic inflation, cosmological inflation or just inflation is the theorized extremely rapid exponential expansion of the early universe by a factor of at least 1078 in volume, driven by a negative-pressure vacuum energy density. The inflationary epoch comprises the first part...
