Research in theoretical physics will include work onsupersymmetric field theories and superstring theory. Supersymmetric field theories hypothesize that for every elementary particle known, there is another particle with very closely related properties. These theories are important because they may be the correct explanation of why the weak nuclear force is not very much weaker than we observe it to be. Superstring theory is important because it is the most promising unified theory of all the fundamental forces, including gravity; it is also leading to the development of new tools for performing calculations in other theories, such as the one which describes the strong nuclear force.

理论物理学的研究将包括工作对称田野理论和超弦理论。超对称场理论假设，对于每个已知的基本粒子，都有另一个具有密切相关特性的粒子。这些理论很重要，因为它们可能是正确解释为什么弱核力量并不比我们观察到的要弱得多。超声理论很重要，因为它是包括重力在内的所有基本力量中最有前途的统一理论。这也导致开发了在其他理论中执行计算的新工具，例如描述强核力量的工具。
