 RESEARCH INTERESTS AND CURRENT RESEARCH WORKS
 
 Differential Geometry.     
 
      
 
 We have done some research on smooth metric measure space with Bakry-Emery Ricci curvature bounded from below and fundamental group of manifolds with lower integral Ricci curvature bound. Motivated and inspired by the recent work of Colding and Colding-Minicozzi. We derive several families of monotonicity formulas for manifolds with nonnegative Bakry-Emery Ricci curvature, extending the formulas in Colding and Colding-Minicozzi.
