This research effort is based on the study of chemical reactions that take place on catalyst surfaces. These processes only take place rapidly when the reactant molecules encounter each other on custom-made catalyst surfaces. The Chinese characters for 'catalyst' can also be used for 'mariage broker'. Our research is aimed at understanding how the catalyst guides and activates the reactants-one couple at a time- towards a happy union. The guiding forces can range from the brutal to the most subtle; the catalyst may need to split the reactants into fragments before the reaction occurs, or it may simply need to induce reaction on one specific face of a molecule as in a chiral reaction. We use a combination of surface science research tools to interrogate the forces that govern the reactivity of single molecular layers in contact with a catalyst surface. The projects are centered on two families of reactions, olefin and alkyne metathesis and chiral catalysis. The molecular details gleaned from these studies are of primary importance to progress in many areas other than catalysis. This is because solid surfaces are used as literally the foundation of many modern technologies such as sensing and nanodevices. The single-layer chemical forces governing cataytic activity also govern the quality of function of such devices.

这项研究工作基于对催化剂表面上的化学反应的研究。这些过程仅在反应物分子在定制催化剂表面相互遇到时迅速发生。 “催化剂”的汉字也可以用于“玛丽亚经纪人”。我们的研究旨在了解催化剂如何一次指导并激活一对夫妇，以实现一个快乐的联盟。指导力量可以从残酷到最微妙的范围。催化剂可能需要在反应发生之前将反应物拆分为片段，或者可能只需要像手性反应中那样在分子的一个特定面上诱导反应。我们使用表面科学研究工具的组合来询问与催化剂表面接触的单分子层反应性的力。这些项目集中在两个反应家族，Olefin和Alkyne Methathess和手性催化。从这些研究中收集的分子细节对于除催化以外的许多领域的进展至关重要。这是因为实体表面实际上被用作许多现代技术（例如传感和纳米版）的基础。掌管活性的单层化学力也控制着此类设备功能的功能质量。
