[3] He is also known for his outreach activities and for his freely available lecture notes covering a wide range of topics in physics.
He completed his MSc in Mathematics at King's College London, and his PhD in Theoretical Physics at Swansea University.
His early work was on solitons and includes the discovery (with Amihay Hanany) of a vortex solution in supersymmetric Yang-Mills theories.
[7] With Eva Silverstein and Mohsen Alishahia, he proposed a new, predictive mechanism for cosmic inflation based on the Dirac–Born–Infeld (DBI) action which helped motivate more systematic analyses of primordial non-Gaussianity.
[9] Tong is known for his widely watched videos on theoretical physics, including a Royal Institution lecture on quantum field theory,[10] and a Quanta Magazine primer on the Standard Model.
