<p> 博士,教授,博士生导师。2003至2006年在香港大学数学系攻读博士学位。2008年至2011年分别在新加坡国立大学淡马锡实验室、香港中文大学数学系从事博士后研究。曾多次访问德国、意大利、新加坡、香港等国家和地区的知名大学。

主要从事科学计算、数字图像处理领域的研究。在SIAM J. Sci. Comput.、SIAM J. Imaging Sciences、SIAM Multiscale Model. Simul.、SIAM J. Matrix Anal. Appl.、Numer. Linear Algebra Appl.、IEEE Trans. Image Process.等期刊发表论文20余篇,目前论文他引次数超过300次。先后主持教育部留学回国基金1项、国家自然科学基金2项,参与香港研究资助局基金2项。其主要研究成果包含两方面:
1). 在数值代数上,为拟Toeplitz矩阵的线性方程组构造了高效实用的结构化预处理子,并对相应预处理矩阵的特征值的分布作出了详细的分析。
2). 在图像处理领域上,发展和提出了基于去模糊和去噪声解耦合的交替最优迭代算法、分裂与正规化算法、优化变换法、原对偶法等快速算法来求解图像复原与重建中的变分问题;分裂与正规化法的提出,促进了对乘子的交替方向迭代 (ADMM) 方法、原对偶方法在图像处理领域上的研究与重新认识。
