研究領域
主要從事李理論與微分幾何、李群表示理論等的研究。主要科研成果包括：構造出第一個李代數上非對稱雙極化的例子，解決了日本數學家金行壯二提出的待解問題；系統研究了齊性仿凱勒流形的幾何性質，最終得到了半單情形的代數分類，這一領域的成果被金行壯二教授稱讚為“輝煌的結果”，並兩次在日本數學會年會上報告；決定了李群表示理論中一類最高權向量環的全部關係，瑞典的審稿人評價此結果“非常令人佩服”；利用李理論，系統研究了芬斯勒幾何的等距變換群和齊性、對稱Finsler空間，相關結果被審稿人評價為“具有國際競爭力”，“是對Finsler幾何的重要貢獻”，Finsler幾何的權威，美國印地安娜大學沈中民教授在美國數學評論上評論我們的結果“opens a door to using Lie group theory to study Finsler geometry”。已發表論文二十多篇。
主要成就
主持過國家自然科學基金青年項目，國家自然科學基金面上項目。1999年與侯自新教授合作的項目《齊性仿凱勒流形的幾何》獲教育部科技進步三等獎。2003年入選“教育部優秀青年教師資助計畫”，2004年入選首屆“新世紀優秀人才支持計畫”。
