本人长期从事规划决策支持系统研究，致力于引入交通领域先进技术与理论，以人的交通行为为导向，探索城市规划设计的事前评估与优化的新方法。该方法的引入，填补了城市规划领域定量方法的不足，完善与提升了城市规划智慧决策支持系统的科学性。在传统的以土地和空间本位的规划设计基础上，申请人创造性地出引入交通领域的基于个体的微观行为模型，结合地理学ArcGIS空间数据与分析技术，对城市TOD（Transit-oriented development）区域建成环境与行人路径选择/交通模式选择行为交互进行仿真模拟。申请人在国际知名期刊及会议上以第一作者发表8篇。任Transportation Research Part D、Travel Behaviour and Society、Frontiers in Public Health、Frontiers in Environmental Science、Journal of Advanced Transportation期刊审稿人。

参与多个国家级基金研究项目，包括国家自然科学基金委员会面上项目, 题目：多元复杂居住满意度视角下农村建成环境形成机理、测度方法及治理策略研究；国家社会科学基金重大项目, 题目：中国相对发达地区基本公共服务均等化与可及性的理论与实践；中华人民共和国科学技术部, 国家重点研发计划项目, 题目：港珠澳大桥智能化运维技术集成应用。

参与荷兰设计周Dutch Design Week（欧洲三大设计展之一），展出项目名称“大型活动中游客参观路径与城市建成环境的互动关系”。相关成果发表于行人疏散动力学会议Pedestrian Evacuation and Dynamics。

此外，本人具有较为丰富的城乡规划与设计实践经验，参与多项城市总体规划、控制性详细规划、乡村规划。
