I am a Professor in the Computer Science and Engineering Department at the Ohio State University. I obtained my M.S and Ph.D degrees from Duke Univ. (where I received the Best PhD Dissertation Award at CS Dept), and B.S. degree from Tsinghua Univ (graduated with First Class Honors). Before joining OSU, I was a post-doctoral researcher at Geometric Computing lab in Stanford Univ from 2004-2005. I received DOE (Dept. of Energy) Career award in 2006, and NSF (National Science Foundation) Career award in 2008. I belong to the TGDA@OSU (Topology, Geometry, and Data Analysis) and the Theory groups at OSU. I am a founding member for the NSF TRIPODS Center at OSU, and a faculty lead for the Foundations CoP for OSU Translational Data Analytics Institute (TDAI @ OSU). I am an associated editor for SICOMP (from 2019) and for JoCG (from 2010). See my CV and the research page for more details.

I am co-chairing the Program Committee for the 35th Intl. Sympos. Comput. Geom. (SoCG) 2019. See CFP here and submit your best papers!

My Erdös number is 2.

I primarily work in the fields of Computational geometry, and Computational and applied topology. My work lies at the intersection of computer science (especially algorithms) and applied mathematics (especially applied topology, discrete and combinatorial geometry). I am particularly interested in developing effective and theoretically justified algorithms for data / shape analysis using geometric and topological ideas and methods. I aim to both provide theoretical understanding of various computational methods developed, and to apply them to practical domains, including computational biology, computational neuroanatomy, geometric modeling, computer graphics and visualization.
