As early as in college at Peking University, I worked as a teaching assistant for an econometrics class. During my PhD study at the University of Chicago, I was selected by the Kenneth C. Griffin Department of Economics to be a graduate instructor for an undergraduate microeconomic core course in two years. I designed course syllabus, slides for 17 lectures, supplementary materials on 6 topics, 5 problem sets, and midterm and final exams. I also worked as a teaching assistant for 6 undergraduate and graduate courses on several subjects in finance and economics, including asset pricing, corporate finance, macroeconomics, and microeconomics.
