人物簡介

多年來一直從事本科生和研究生教學,主講多門本科生課程,一直擔任研究生的學位課程,如樣條函式、(多變數)函式逼近論、計算代數幾何,以及計算機輔助幾何設計的教學工作。從1983年開始培養碩士生,1993年開始培養博士生,至今已培養畢業11名博士生,20多名碩士生。
從上世紀七十年代後期開始,從事三次樣條、Bézier曲線等套用研究,1979-81年在美國Wisconsin大學數學研究中心,跟隨de Boor教授系統地學習了樣條函式和函式逼近論的基本理論,並完成了多篇研究論文。81年回國後,從事計算機輔助設計和圖形學,以及數值逼近等方向的研究,並從上世紀八十年代開始,一直承擔中科院、教育部(教委)和自然科學基金委的研究課題。
二十多年來已在國內外學術刊物上發表論文70多篇,其中20多篇論文發表在SIAM,CAGD, Graphical Models, JAT, CAT, BIT, JCAM等國際著名刊物上,早期主要從事曲面的保型和逼近、三角域上B-B曲面、樣條函式等方面的研究,取得了一系列令國內外同行所關注的成果。近幾年來,在代數曲面造型,把分片代數曲面套用於構造過渡曲面及補洞等方面做了具有國際水平的研究成果。曾獲中科院自然科學貳等獎。在動態隱式曲線、曲面重構的理論和套用方面做了一些初步的工作。
