About

I am a postdoctoral Research Fellow at The Earth Commons Institute at Georgetown University, where I work with Prof. Roshanak (Roshi) Nateghi. I earned my Ph.D. in Operations Research and Industrial Engineering from The University of Texas at Austin in 2026, advised by Prof. John J. Hasenbein and Prof. Erhan Kutanoglu.

My research develops optimization and data-driven decision models for infrastructure systems exposed to extreme events and long-term climate risk. I am particularly interested in how uncertainty, resource constraints, and the unequal consequences of service disruptions should shape resilience investments and emergency-response decisions.

My doctoral research addressed power-grid hardening, healthcare-facility protection, patient evacuation, emergency resource allocation, long-run disaster impacts, and electricity system planning. Methodologically, my work draws on stochastic optimization, mixed-integer programming, multi-objective optimization, decomposition algorithms, and statistical modeling.

Before joining Georgetown, I also conducted research at the National Renewable Energy Laboratory on electric-vehicle charging flexibility and electricity-system planning. I hold an M.S. in Operations Research and Industrial Engineering from The University of Texas at Austin and a B.S. in Civil Engineering, with highest honors, from Boğaziçi University.
