Philosophy of the Mind and Cognitive Science, Hermeneutics, Social Epistemology
BA College of Wooster
MA University of Chicago, Humanities

YF’s philosophical passion has been surrounding the (very general) topic of human understanding. This passion has both a theoretical face and a practical face: with the former, it is spent on various discussions in the philosophy of mind and cognitive science, hermeneutics, and social epistemology; while with the latter, it is concerned with living a good philosophical life – to philosophize virtuously with other philosophers, to learn from people from different social groups, and to practice the (theoretically arrived) ideology critiques in the material life.

Outside of academics, YF is a culinary enthusiast who has served many people with their food as well as won some competitions. You may also very likely find them working out at the gym or playing ball games.
