Research Training
2024 I joined the PEESE group under the supervision of Prof. Fengqi You, continuing research on AI methodologies for microscopy and electrocatalysis. The new journey begins and the following work is yet to come...... (Publication [13]-[15])
2022 Senior year, I was selected (out of 9 nationwide) to participate in a joint master's program (two years) at the National University of Singapore, and was fortunate to meet a distinguished microscopist (advisor Prof. Qian He), under whose guidance my research direction took a major shift towards the integration of artificial intelligence methods with scanning transmission electron microscopy, to investigate supported metal catalysts. (Publications [7], [8], and [10]-[12])
2021 Junior year, I joined a hydrogen energy lab (advisor Prof. Hui Liu) and embarked on research on nano-catalytic materials for water electrolysis and fuel cells, which eventually led to my very first step in academics - an first-authored research article published in ACS Appl. Energy Mater (Publication [9]). At the same time, I have also participated as a contributing author in several related projects (Publications [2]-[6]).
2020 Sophomore year, I first started quantum dot-related research in a semiconductor lab as the leader of a undergraduate research team. (Publication [1]).
2019 Freshman year starts with a major in condensed materials physics.
