ABOUT

I am a Professor of Economics at Chulalongkorn University specializing in fiscal policy, taxation, and public finance. My work examines how tax and spending policies influence household behavior, firm decisions, and long-term fiscal sustainability, with a particular focus on emerging and developing economies.

 

A central part of my work is aimed at strengthening fiscal accountability by improving the quality of policy design, empirical evaluation, and public understanding of fiscal choices and their long-term implications.

​

Over the years, I have had the opportunity to advise public agencies and policymakers on fiscal and tax issues, including serving as an advisor to Thailand’s Minister of Finance, and working with tax authorities and international organizations such as the Asian Development Bank, the World Bank, and UNESCAP. My recent policy work has covered carbon tax design, the global minimum tax (Pillar 2), SME taxation, tax reform, and behaviorally informed approaches to tax administration.

​

Previously, I worked as an economist at the U.S. Congressional Budget Office in Washington, DC, focusing on federal tax policy and revenue analysis, and later as a senior economist at Siam Commercial Bank. My academic research has been published in international journals.

​

I have also been fortunate to receive research support and recognition, including selection as a 2026 Global Eisenhower Fellow and several academic research awards, among them the Richard Musgrave Prize from the National Tax Association. Much of my work is motivated by the goal of strengthening fiscal accountability, through research and policy engagement that help ensure fiscal decisions are informed by evidence, institutional realities, and long-term sustainability.
