Physicists have learned that all matter and energy can be assembled from a small number of different types of fundamental particles.  The theory which describes these particles has been so successful that it has been dubbed the ``Standard Model''.  There is a catch, though: nobody can exactly solve the equations which predict what the particles will do in an experiment.  Instead, approximations have to be made, and the more accurate the approximation, the more difficult it is to calculate the answer.  My research uses computers in uncommon ways in order to improve the accuracy of the theoretical predictions of the Standard Model.  These predictions can then be compared with experimental data in order to gain new insights about the inner workings of the world at its smallest scales.

物理学家们已经认识到，所有的物质和能量都可以从少量不同类型的基本粒子中聚集起来。描述这些粒子的理论非常成功，以至于被称为“标准模型”。然而，这其中有一个问题：没有人能精确地解出预言粒子在实验中会做什么的方程。2相反，必须进行近似，近似值越精确，计算答案就越困难。我的研究以不同寻常的方式使用计算机，以提高标准模型理论预测的准确性。然后，这些预测可以与实验数据进行比较，以获得关于世界在最小尺度上内部运作的新见解。
