1. Development Economics
I consider myself primarily a development economist. Recently, I focus on poverty alleviation issues (especially those related to cash transfer and migration), innovation, and environmental policies. Concurrently, I am interested in healthcare policies that affect people's well-being in developing contexts. I have conducted studies investigating human capital accumulation (affected by on-the-job training, family planning, etc.), migration, and income mobility.

2. Applied Microeconomics/Microeconometrics
I also devote to applying microeconomics and microeconometrics to policy evaluation, analysis, and design. I do not particularly prioritize structural approaches over reduced-form methods, but many times I do prefer recovering the structural "deep" parameters to understand the welfare consequences of existing and counterfactual policies.

Finally, I do have a few other research interests. One important topic that I am enjoying exploring is precarious employment. This is an issue that is not unique to the developing world. In fact, it is quite widespread in developed countries. Moreover, I am a fan of international trade and (both inward and outward) foreign direct investment. While having a broad interests, I do prioritize my time in the previous two areas.
