Ph.D. Students

Yunfei Wang

LinkedIn | Google Scholar | E-mail: [email protected]

B.Sc. Materials Science and Engineering, University of Science and Technology Beijing, 2016

Yunfei has been developing materials for electrochemical energy storage and conversion since 2014. After joining JHU in 2016 as a Ph.D. student, he has been devoted to designing new synthesis routes of alloys by electrochemical techniques, including deposition and dealloying. The alloy materials will be implemented to fuel cells and batteries to advance clean energy. Yunfei enjoys photography when he is not working in the lab.


Zhuoqun (Zoey) Zhang

E-mail: [email protected]

B.S. Chemistry, University of Science of Technology of China, 2014

Zhuo-Qun interests in electrocatalysis, infrared spectroscopy, and electrolyte effects on electrochemistry. Her undergraduate research was on the shape-controlled synthesis of metal nanoparticles. She joined the Hall research group in 2016. Her research focuses on electrochemical catalysis of CO and CO2 reduction in the electrolyte with molecular additives. In her spare time, she likes traveling, hiking, and chatting with friends.


Tianyao (Ty) Gong

LinkedIn | Google Scholar | E-mail: [email protected]

B.E. Materials Science and Engineering, Beihang University, 2017

M.S. Materials Science and Engineering, Columbia University, 2019

Before joining the Hall lab in 2019 fall, Ty worked on synthesis & morphology control of nano-sized amorphous materials and engineering the interfaces within solid-state lithium-ion batteries. As for now, his research focuses on phase transformation under electrochemical dealloying in intermetallic alloy systems and electrocatalytic performances. In his free time, Ty likes playing tennis, having jam sessions with friends, and re-watching and quoting the TV show “Friends” (already over 10 times for all 236 episodes).


Hao (Nick) Zhang

B.S. Chemical Engineering, University of California, Berkeley, 2018

NSF Graduate Research Fellow

Prior to attending Hopkins, Nick conducted research in the bioimaging field at Berkeley. His research entailed enhancing NMR signals through catalytic hyperpolarization. Later, he joined Brookhaven National Laboratory to work on in situ/operando characterization of battery materials using National Synchrotron Light Source-II (NSLS-II). Nick joined the Hall group in Fall 2020 as a Ph.D. student. He is currently investigating the effect of ionic liquids on electrocatalytic performance. He aims to investigate the electrolyte interface and reaction intermediates with a combination of characterization techniques. In his free time, Nick enjoys hiking, baking, traveling, and practicing the ukulele.
