I am a resourceful applied microeconomist with over ten years of experience in national and international academic & policy research, as well as impact evaluation. I use cutting-edge causal inference and econometric techniques to explore topics at the intersection of agricultural, development, and welfare economics. I possess an exceptionally strong profile in applied econometrics, along with a proven track record of high-quality economics research, including peer-reviewed publications and presentations at international conferences. I am an interdisciplinary researcher by nature.

Below, you’ll find detailed lists of my (1) ongoing research and (2) peer-reviewed publications.
