TASI 2021 Applications Closed


TASI has been held each summer since 1984, originally at Michigan, Yale, Santa Cruz, Santa Fe and Brown, and since 1989 in Boulder. Each year, typically, some sixty of the most promising advanced theory graduate students in the United States, along with a few beginning postdocs and experimental graduate students, have attended TASI. TASI 2021, titled “Black Holes, Quantum Information, and Dualities,” will be held from Monday, June 7 to Friday, July 2 at the University of Colorado Boulder. The emphasis shifts from year to year, but typically, there have been courses of lectures on phenomenology, quantum field theory, string theory, and the particle/astrophysics interface, as well as seminars on other theoretical and experimental topics. It has been highly successful, especially in introducing students to a broader range of ideas than they normally experience at their home institutions or while working on their dissertation topics.

The themes of recent TASI schools were "The Obscure Universe: Neutrinos and Other Dark Matters”, “The Many Dimensions of Quantum Field Theory", and “Anticipating the Next Discoveries in Particle Physics".

TASI has limited funds to support participants. In past years, most of the participants were given partial support to take care of the cost of meals and accommodation at one of the residence halls on campus and some travel expenses.

TASI is managed by a Scientific Advisory Board. Presently, its members are L. Dixon, Chair (SLAC), M. Cvetič (Penn), L. Rastelli (Stony Brook), L. Reina (Florida State), K. Scholberg (Duke), and T. Tait (Irvine). The General Directors are Oliver DeWolfe and Ethan Neil (Colorado). Thomas DeGrand was General Director from 2014-2020, and K. T. Mahanthappa was General Director from 1989-2013.

TASI is supported by the University of Colorado, Boulder and The National Science Foundation.

COVID-19 Impacts

Due to the ongoing COVID-19 pandemic, the format for TASI 2021 is not yet determined. If possible consistent with university and government health requirements, we will have TASI 2021 in a hybrid model where some students and lecturers attend in person, while those who prefer attend remotely. If this is not possible, TASI 2021 will take place entirely online. TASI 2020 took place entirely online, including social aspects, and was successful in that format.


Boulder is forty miles from Denver International Airport. The campus is located at the foot of the Rocky Mountains at an elevation of 5400 feet. The weather during June is usually quite pleasant, with a temperature range of 55° F to 85° F, low humidity, and regular afternoon thunderstorms. A sweater is a necessity and rain gear is useful.

Housing and Meals

In a typical year, students are housed in one of the residence halls on campus, two people per room. There are a few single rooms. Each room is equipped with two single beds. Assuming in-person attendance, we expect arrival on June 6 (Sunday) and departure on July 3 (Saturday). All weekday meals and Saturday brunch will be provided, except on July 3. The cost of lodging and board for this period will be approximately $1700 per person. COVID-19 impacts to the previous are yet to be determined.

Registration Fees

As per the laws of the State of Colorado and the policies of the University of Colorado Boulder, all registrants should hereby be aware that some portion of the registration fee will be used to purchase alcoholic beverages.
