长期从事利用卫星、地面、航空等观测数据确定全球重力场模型及其地学应用的研究。研究成果为确定高精度高程基准奠定了坚实基础，用于GF-7号卫星全球测图几何高程向海拔高程的高精度转换；研制的卫星重力梯度任务仿真分析平台被用于我国自主重力梯度卫星系统的总体指标设计与分析。主要贡献包括：

• 构建了220阶次纯GOCE卫星重力场模型GOSG01S（http://doi.org/10.5880/icgem.2018.002）以及300阶次GOSG02S，模型精度与同期欧空局发布的最优模型时域解（TIM）相当，GOSG01S被收录在国际权威全球重力场模型发布网站ICGEM上；

• 联合卫星重力、卫星测高及地面重力自主研制并发布了SGG-UGM-1/2系列模型。模型空间分辨率和精度在当前我国公开发布的超高阶重力场模型中均为最高，整体精度均优于美国发布的国际权威模型EGM2008。SGG-UGM-1和SGG-UGM-2模型均在国际权威网站ICGEM上发布（http://doi.org/10.5880/icgem.2018.001），SGG-UGM-1是我国首个在ICGEM网站发布的超高阶重力场模型；

• 在国际上首次采用全球重力场建模的方法由GOCE卫星重力梯度观测值探测到2011日本大地震的同震重力(梯度)变化，对未来卫星重力任务设计具有参考意义。

• 构建了多种测量模式（重力梯度、卫星跟踪卫星）的重力卫星系统的指标分析和数值仿真平台。
