Research in theoretical physics will focus on questions in elementary particle physics and astrophysics. The physical, astrophysical, and cosmological consequences of theories in which space has more than threedimensions will be explored. Ramifications of "duality relations" demonstrating that seemingly different string theories are actually different forms of the same theory will be studied. Small effects that will test our present understanding of the forces between the elementary particles and possibly signal the presence of new physics beyond our present understanding will be theoretically analyzed. The possibility that space has more than three dimensions is extremely interesting, and the exploration of its consequences is very important. String theory is the leading candidate for a theory that unifies our understanding of all the basic forces of nature, so further progress in this theory is important as well. Finally, small effects have been a fruitful testing ground for our understanding of physics in the recent past, so new analyses of such effects is very timely.

理论物理学的研究将集中在基本粒子物理学和天体物理学的问题。 物理，天体物理学和宇宙学的理论，其中空间有超过三维的后果将被探讨。 “对偶关系”的分支表明，看似不同的弦理论实际上是同一理论的不同形式将被研究。 将测试我们目前对基本粒子之间的力的理解，并可能标志着超出我们目前理解的新物理学的存在的小效应将被理论分析。 空间有超过三维的可能性是非常有趣的，探索其后果是非常重要的。弦理论是统一我们对自然界所有基本力的理解的理论的主要候选者，因此该理论的进一步发展也很重要。 最后，在最近的过去，小效应一直是我们理解物理学的一个富有成效的试验场，因此对这种效应的新分析是非常及时的。
