Undergraduate teaching

He teaches two undergraduate courses "Solid State Physics," "2D Materials and Devices," and "Low-Dimensional Physics and Functional Materials." He attempted a teaching approach that integrates basic theory, cutting-edge literature, and experimental practice. Course rating has topped 4.97 for three consecutive years (on a 5-point scale). The course was selected as the exemplary high-quality course of Daxia School (an online course platfrom constructed by ECNU). He also leads projects on educational research under the Ministry of Education as a principal. The image presents a custom-developed maskless non-direct write lithography system, capable of a 1000nm resolution, and employed in academic and research settings.
