I am currently working with Prof. Dimitris Metaxas at Computational Biomedicine Imaging and Modeling Center , Rutgers University . From 2009 to 2012, I worked with Prof. Herbert Edelsbrunner at Institute of Science and Technology Austria. I obtained my Ph.D. degree from Rensselaer Polytechnic Institute in 2009 (advised by Prof. Daniel Freedman).

My research focuses on data and image analysis, with an emphasis on the usage of topological and geometric methods. In particular, I am interested in using theories in quantitative computational topology, e.g. persistent homology, to extract and analyze structures of data of modern age.
