My research program is in differential geometry, an area of pure mathematics which studies the existence and properties of certain kinds of geometric shapes in high dimensions. Current theories of physics for very small distances and large energies (superstring theory and supergravity) require for their description some geometric shapes of dimensions 7 and 8, possessing special properties related to their curvature. These objects have also been of independent mathematical interest, because they are closely related to some strange exceptions that arise in algebra. The goal is to study the possible types of geometric shapes that can exist with these special curvature properties. This will contribute to a better understanding of the physical theories and the beautiful mathematics which is needed to describe them.

我的研究方向是微分几何，这是纯数学的一个领域，研究高维空间中某些几何形状的存在性和性质。目前的物理学理论对于非常小的距离和大的能量（超弦理论和超引力）的描述需要一些7维和8维的几何形状，拥有与它们的曲率有关的特殊性质。这些对象也有独立的数学兴趣，因为它们与代数中出现的一些奇怪的例外密切相关。我们的目标是研究可能存在的几何形状，这些特殊的曲率属性的类型。这将有助于更好地理解物理理论和描述它们所需的美丽数学。
