Research in theoretical physics will cover a broad spectrum of topics focussed on string and M theory, and on cosmology. String and M theory are our best candidates for a theory that can unify all the basic forces of nature, including gravity. Efforts will be made to make progress towards a fundamental formulation of string and M theory, and to sharpen our ability to calculate in these theories, so as to ultimately be able to make contact with experimental data. In cosmology, research will include attempts to understand the "cosmological constant," whose apparent presence in nature is resulting in the acceleration of the expansion of the universe. The presence and nature of the cosmological constant is one of the outstanding puzzles in cosmology.

理论物理学的研究将涵盖广泛的主题，重点是弦和M理论，以及宇宙学。 弦理论和M理论是我们最好的候选理论，可以统一自然界的所有基本力，包括引力。 我们将努力在弦理论和M理论的基本公式方面取得进展，并提高我们在这些理论中的计算能力，以便最终能够与实验数据联系起来。 在宇宙学中，研究将包括试图理解“宇宙常数”，其在自然界中的明显存在导致宇宙膨胀的加速。 宇宙常数的存在和性质是宇宙学中的一个突出难题。
