While pursuing his Ph.D. in Geography, Yifan also took courses in Philosophy and Computer Science. His philosophical thinking has motivated him to think of information systems from diverse perspectives, and has provided him insights into the development of GIS. During college, Yifan worked as a volunteer teacher in the farms of Phonsavang, Laos, and in Sukabumi, Indonesia, where he interacted with children and low income populations. Such experiences have motivated him to devote his expertise to help people and the community.
