I am working on improving parton distribution functions (PDFs), which describe the structure of protons, in the era of high precision experimental measurement at the Large Hadron Collider. I am predominantly working on doing this in two ways: firstly, by developing a framework for the systematic inclusion of theoretical uncertainties in PDFs; and secondly, by including new experimental data in PDF fits. Regarding the former, my work is focused on the inclusion of missing higher order uncertainties, and regarding the latter, my work is focused on the inclusion of single top production data. I will also work on PDF-related Standard Model and/or Beyond the Standard Model phenomenology.

在大型强子对撞机进行高精度实验测量的时代，我正在致力于改进描述质子结构的部分分布函数（pdf）。我主要通过两种方式来做这件事：首先，通过开发一个框架来系统地在pdf中包含理论不确定性；第二，通过将新的实验数据包含在PDF文件中。对于前者，我的工作重点是包含缺失的高阶不确定性，对于后者，我的工作重点是包含单个顶部生产数据。我也会研究pdf相关的标准模型和/或超越标准模型现象学。
