Yu-hsien Sung is a Ph.D. candidate in political science at the University of South Carolina. She was a Fulbright fellow and a pre-doctoral fellow in the Institute of Political Science at Academia Sinica. Broadly, her research is about the political incentives of key actors in the legal system, with a focus on how mechanisms of accountability shape behaviors. Her doctoral dissertation examines how US local chief prosecutors exercise policy-oriented discretion to generate support from their principals in ways that vary across selection methods. She also studies comparative constitutional courts. Her recent work traced the political foundations of Asia’s first same-sex marriage decision.
