Research Interests: My work explores how governments and institutions can support the well-being of displaced people and their "host" communities around the world. I enjoy using diverse methodological approaches including qualitative analysis, statistical causal inference, and latent variable modeling to better understand populations' and policymakers' experiences. My dissertation research explores social determinants of mental health among displaced Syrians living in Jordan.
