Zarrar Khan is a Senior Expert in Integrated Assessment Models with over a decade of experience linking climate, energy, water, and land systems to inform national net-zero strategies and resilience planning across the Americas, Europe, Asia, and the Middle East. He has led multi-institutional modeling teams at PNNL and Climate Analytics and advised multilateral and US agencies (World Bank, IDB, USAID, DOE, State Dept.) on policy-ready analysis and capacity building. His work spans end-to-end model integration, containerized multi-sector tooling, and interactive dashboards—delivering scalable software like Metis and GCIMS to bridge research and stakeholder decision-making. Zarrar combines deep technical rigour from a PhD in Sustainable Energy with hands-on engineering roots in geotechnical and hydropower projects, giving him rare cross-domain fluency. Equally comfortable coding model pipelines and convening ministerial workshops, he excels at turning complex, multi-scale evidence into actionable climate and investment guidance.
