Dr. Sahar Yousef is an Assistant Professor of Development Economics at the Doha Institute for Graduate Studies. She holds a Ph.D. in Applied Economics from The Ohio State University. Her research lies at the intersection of political economy, development economics, and international trade, with a particular focus on conflict, climate change, and food systems. She examines how environmental and economic shocks interact with political institutions and trade policies to shape conflict dynamics, food insecurity, and social welfare. Her work also explores the role of trade and peace agreements in mitigating territorial conflict. Her current projects investigate the impact of climate change on agriculture, food prices, food security, and social unrest, with special attention to the mediating effects of food subsidies, trade openness, and humanitarian aid. She also conducts impact evaluations and distributional welfare analyses to assess the equity and efficiency consequences of policy interventions and conflict shocks.
