Personal profile
Research interests
My research centers on operations and supply chain management, with a focus on decision-making under uncertainty, supply chain coordination, and sustainability. I develop analytical and data-driven models—spanning stochastic programming, distributionally robust optimization, and reinforcement learning—to support strategic and operational decisions in complex supply chains. My earlier work has laid the groundwork in inventory theory and sourcing under uncertainty, while more recent contributions address real-world challenges such as production planning in high-tech industries, adaptive logistics in dynamic environments, and humanitarian aid planning under climate risk. Across these domains, I aim to bridge theory and practice, improving supply chain resilience, efficiency, and societal impact.
