Dr. Donghoon Shin


Donghoon Shin received his Ph.D. in Materials Science and Engineering from Northwestern University under the supervision of Prof. Chad A. Mirkin. In 2024, he joined the Sargent lab as a postdoctoral fellow. His research centers on advancing halide perovskite tandem solar cells, with a particular focus on understanding carrier dynamics and photophysics at layer interfaces.

Dr. Yongxiang Liang


Yongxiang Liang received his Ph.D. degree at University of Science and Technology of China on December, 2023, under the supervision of Prof. Jie Zeng. His Ph.D. studies mainly focused on the structure-performance relationship of catalysts in CO2RR and CORR. He joined the Sargent Group as a postdoctoral fellow on February 2024 with research interests in propylene epoxidation and energy storage.

Dr. Qiuchen Chen


Dr. Qiuchen obtained his BSc degree from Shantou University in 2015 under Prof. Xiao-Chun Huang, specializing in photocatalytic applications of MOFs. Completing a Ph.D. at Technion (2021) under Prof. Zeev Gross, the focus continued to catalytic and pharmaceutical activity of metallo-corrole and sapphyrin complexes. During a UChicago postdoc (2021-2024) with Prof. Anna Wuttig, Qiucheng delved into organic electrosynthesis for C(sp3)-C(sp3) bond formation with interfacial design. Since January 2024, Qiucheng has been a member of the Sargent group, contributing expertise to CO2 upgrading research. Outside the lab, you can find him around the gym and some Chinese restaurants.

Dr. Chongwen Li


Chongwen Li is a postdoctoral researcher at Northwestern University, currently leading the perovskite-based hybrid multi-junction subgroup in the Sargent group. He earned his PhD in Physics from the Wright Center for Photovoltaic Innovation and Commercialization at the University of Toledo. His research interests include novel semiconductor materials and the design of multi-junction configurations for renewable energy applications, such as photovoltaics and photoelectrochemical catalysis.

Dr. Payel Mondal


Payel received her Ph.D. in Chemistry from JNCASR Bangalore, India in 2022 under the supervision of Prof. Ranjani Viswanatha. Her Ph.D. work was mainly focused on studying the fundamental photophysics of transition metal doped II-VI semiconductor quantum dots. She joined the Sargent group as a postdoctoral fellow in November 2023. Her current research interest involves the surface engineering of colloidal quantum dots to enhance photodetector performance.

Dr. Stefan Zeiske


Stefan received his Ph.D. degree in January 2022 under the supervision of Prof. Paul Meredith and Prof. Ardalan Armin at Swansea University, United Kingdom. His Ph.D. studies mainly focused on the optoelectronic characterization of charge generation and recombination processes in organic solar cells and photodetectors. He joined the Sargent group as a postdoctoral researcher in November 2023. His current research interest lies in single-junction perovskite solar cells and colloidal quantum dot near-infrared photodetectors.
