My current research focus is the theory of exceptional orthogonal*polynomials. Classical orthogonal polynomials are a fundamental*mathematical tool with applications ranging from atomic physics and*the design of electrical circuits to fundamental algorithms utilized*in scientific computation.**Exceptional orthogonal polynomials are a new and fascinating*generalization of the classical concept. They also arise as solutions*of second-order differential equations, but allow for the possibility*that the resulting family of polynomials does not contain every*degree. This mild relaxation of the theoretical assumption leads to a*much richer set of examples with an attendant increase of flexibility*in applications such as super-symmetric quantum mechanics.**Working with collaborators, I introduced and developed these novel techniques back in 2008-2009.*Since then the field has seen rapid growth with many exciting developments both in applications and theory.*My research goals is to focus on the theoretical underpinnings of exceptional orthogonal polynomials with a view*towards exploring novel connections with existing branches of mathematical theory.

我目前的研究重点是例外正交 * 多项式理论。 经典正交多项式是一种基本的 * 数学工具，其应用范围从原子物理学和 * 电路设计到科学计算中使用的基本算法。特殊的正交多项式是经典概念的一个新的且令人着迷的 * 推广。 它们也作为二阶微分方程的解出现，但考虑到所得到的多项式族不包含每一个次数的可能性。 这种对理论假设的温和放松导致了一组更丰富的例子，并随之增加了超对称量子力学等应用中的灵活性。早在2008-2009年，我就与合作者合作介绍并开发了这些新颖的技术。*从那时起，该领域已经看到了快速增长，在应用和理论方面都有许多令人兴奋的发展。我的研究目标是专注于特殊正交多项式的理论基础，以期探索与数学理论现有分支的新联系。
