I am an assistant professor at the International College of Innovation at the National Chengchi University (國立政治大學創新國際學院).
I study what happens when governments use policy tools to build a fairer and better society: what has to be given up, who ends up bearing the cost, and whether these policies actually work as intended. As an empirical public policy scholar working at the intersection of public economics, education policy, and public administration, I pursue these questions across four connected areas: education and equality of opportunity; taxation and housing; how families respond to sudden changes in wealth and income; and how governments themselves are managed.
My recent work examines whether equity-based admission reforms come at the cost of student achievement, whether taxing properties at their true market value improves tax fairness at the expense of housing affordability, whether promoting minorities into leadership places hidden burdens on minority supervisors, and how windfalls from lottery wins reshape family decisions such as marriage and childbearing.
Across projects, the throughline is a commitment to evidence-based governance: figuring out where fairness and efficiency truly conflict, where the conflict is only apparent, and how better policy design can serve both at once. Working with government agencies, I translate these findings into practical recommendations for fairer resource distribution and more accountable public institutions.
I earned a PhD in Public Affairs from the University of Missouri’s Harry S Truman School of Government and Public Affairs in 2025. I also hold an MPA (Master of Public Administration) from National Chengchi University (Taiwan, 2019) and a BA in Political Science from National Taiwan University (2015); before beginning graduate study, I worked in the Congress of Taiwan.

我目前任職於國立政治大學創新國際學院（International College of Innovation）擔任助理教授。
我關注政府如何運用政策工具建構更公平、良善、宜居的社會。我的研究探討：這些政策必須付出什麼代價、誰承擔了成本，以及政策是否真正達成預期效果。作為一位橫跨公共經濟學、教育政策與公共行政領域的實證公共政策學者，我的研究具體深耕四個核心主題：(1) 教育與機會均等；(2) 租稅公平與居住正義；(3) 家庭如何因應財富與所得的突發變化；以及 (4) 政府內部的管理與治理。
我近期的研究包含：以公平為導向的入學改革改革是否犧牲了學生的學業成就；房產稅實價課稅在追求租稅公平的同時是否犧牲了居住正義；晉升少數群體至領導職位是否為少數群體主管帶來隱藏的負擔；以及機會中獎帶來的意外之財如何改變婚姻與生育等家庭決策。
貫穿這些研究計畫的核心關懷是透過「循證治理」的取徑，釐清公平與效率何時衝突、何時又得以共榮，並探討公共政策能夠兼顧不同價值的機制。透過與政府機關合作，我將這些研究發現轉化為促進資源公平分配、提升公共機構問責的實務建議。
我於2025年取得美國密蘇里大學杜魯門政府與公共事務學院（Harry S Truman School of Government and Public Affairs）公共事務博士學位，並持有國立政治大學公共行政碩士（2019）與國立臺灣大學政治學系學士（2015）學位；在攻讀研究所之前，我曾任職於立法院。
