  • Research Interests

    Math and physics trained, I am trying to contribute theoretical and algorithmic efforts to management, industrial and policy studies from a data-driven, network-oriented & dynamic-control perspective. I am interested in analyzing the underlying physics in social-economic processes, and more so in bringing them out through advanced math tools so as to guide real-world managerial practice as well as policy decision-making.

About Me

Who Am I?

Hi I'm Tianyi Li, PhD candidate in the System Dynamics Group at the MIT Sloan School of Management, expecting to graduate in 2021. I was trained in math and physics during college (Peking University) and masters (Princeton University). I analyze the dynamics and models of social systems and human networks, and try to contribute theoretical and algorithmic efforts to management, industrial and policy studies from a data-driven, network-oriented & dynamic-control perspective. [See More]

During my doctoral studies, I had the experience to teach undergraduate, MBA and EMBA students. I also served as coach for Sloan summer program working with industrial employees (Accenture). [See More]

In my non-academic life, I am a semi-professional sportsperson interested in marathon, kickboxing, fitness and basketball. I sometimes do drama-acting and writing.

In my doctoral research, I am trying to contribute theoretical and algorithmic efforts to management, industrial and policy studies from a data-driven, network-oriented & dynamic-control perspective. With my background, I am extremely interested in analyzing the underlying physics in social-economic processes with the ubiquitous existence of human factors, and more so in bringing these physics out through appropriate mathematical tools, such as graph theories, control theories and machine-learning techniques, so as to assist social science modelers with well-functioning algorithms that could possibly help guide real-world managerial practice as well as policy decision-making. In my future research works, I would try to bring these theoretical efforts to applicational fields at more traditional management science branches, such as marketing and finance, upon which to get engaged in more topic-oriented studies.
