Hagan is a first-year MPP candidate at the Jackson School of Global Affairs originally from Los Angeles and Shanghai. At Jackson, Hagan aims to explore how climate policy issues intersect with trade, equity, and geopolitics. 

Before Yale, Hagan worked at Clean Air Task Force (CATF) on accelerating the deployment of clean hydrogen and its derivatives to decarbonize hard-to-abate sectors like chemical production and heavy-duty transportation. He led the hydrogen team’s analysis and advocacy on key rule-makings, including the Environment Protection Agency’s 111(d) power plant regulations and the Treasury Department’s implementation of the Inflation Reduction Act's 45V Hydrogen Production Tax Credit. 

Prior to CATF, Hagan held various engineering, operations, and business roles at Air Products and Chemicals (AP). He coordinated hydrogen and carbon monoxide production for the world’s longest hydrogen pipeline and AP’s Texas carbon monoxide network. He also analyzed market viability for low carbon hydrogen and ammonia, supported maintenance outages at the Port Arthur hydrogen and carbon capture plants, modeled patented natural gas liquefaction processes, and provided process support for contract negotiations in Algeria.

Hagan graduated cum laude from Cornell University with a major in chemical engineering. He is fluent in Mandarin and Cantonese and is conversational in French.
