Personal Statement: 

I was born in 1983 in Huangshi, Hubei province, China. I received my B.S. in Mathematics and Physics from Tsinghua University in 2004, and obtained my Ph.D. from Institute of Physics, Chinese Academy of Sciences in 2009. From 2009 to 2013, I worked as a Postdoctoral Associate at the Physics department of University of Florida. Since 2013 I became a Senior Postdoctoral Associate at the Department of Materials Science and Engineering, Massachusetts Institute of Technology, and Program Manager for the Samsung-MIT Alliance in Materials Design for Energy Applications. 

My interests lie in the cross-disciplinary research of condensed-mater physics and materials science at the technological frontier. Reflecting this I worked with my PhD co-advisor Dr. Xiaoguang Zhang (currently of Univ. Florida Physics) on the theory of electronic transport in spintronics. I also worked with my previous postdoctoral advisor Prof. Hai-Ping Cheng (Univ. Florida Quantum Theory Project) on molecular electronics and heterogeneous catalysis. My current postdoctoral research with Prof. Gerbrand Ceder at MIT (now at UC Berkeley and LBNL) further extends my physics expertise to the burgeoning materials research area of all-solid-state Li-ion batteries using high-throughput materials genome and computational materials informatics.

Thesis Title: 

Design principles for solid-state lithium superionic conductors

Thesis Abstract: 

Lithium solid electrolytes can potentially address two key limitations of the organic electrolytes used in today’s lithium-ion batteries, namely, their flammability and limited electrochemical stability. However, achieving a Li+ conductivity in the solid state comparable to existing liquid electrolytes (>1 mS cm−1) is particularly challenging. In this work, we reveal a fundamental relationship between anion packing and ionic transport in fast Li-conducting materials and expose the desirable structural attributes of good Li-ion conductors. We find that an underlying body-centred cubic-like anion framework, which allows direct Li hops between adjacent tetrahedral sites, is most desirable for achieving high ionic conductivity, and that indeed this anion arrangement is present in several known fast Li-conducting materials and other fast ion conductors. These findings provide important insight towards the understanding of ionic transport in Li-ion conductors and serve as design principles for future discovery and design of improved electrolytes for Li-ion batteries.
