Together with Gia Dvali, he suggested the idea of brane inflation in 1998 in which inflation arises because of the weak forces supersymmetry allows between identical branes.[4] A variant of this proposal based on branes and antibranes [5] was later put on concrete string theoretic grounds by Shamit Kachru and collaborators.[6] 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.[7] At that time they were both postdocs at Cornell University. Tye went to China for six weeks in 1979 during the time that Guth came up with his historic inflation breakthrough. "Had he not gone to China, Henry surely would have been a coauthor on the first inflation paper," Guth said.[8]
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.
