Ploy Achakulwisut

Research Fellow

On leave of absence

Ploy Pattanun Achakulwisut is a Research Fellow with SEI Asia. Her policy research and stakeholder engagement focuses on the climate, air pollution, and health impacts of fossil fuels and food systems. She co-leads SEI’s Carbon Lock-in Initiative and serves as a coordinating lead author and lead analyst of the Production Gap Report series, which tracks the misalignment between governments’ planned fossil fuel production and the global levels consistent with the Paris Agreement. Her other projects include evaluating the health impacts and inequities of air pollution from oil and gas production and use, and assessing the public health implications of low-carbon diets. In 2020–2022, Ploy also served as a working group member of the Lancet Countdown US Policy Brief series. Ploy joined SEI US in 2019 and transferred to SEI Asia in 2023.

Prior to joining SEI, Ploy was a postdoctoral scientist at The George Washington University. She has also served as a SustainUS youth delegate to the 2014 United Nations climate negotiations, led campaigns to engage youth and academics in climate advocacy, and published op-eds in outlets including The GuardianMashable, and Scientific American. Her research and advocacy led to her being named in 2019 as one of Grist Magazine’s “50 Fixers”, an annual list of “emerging leaders from across the US who are working on fresh, real-world solutions to our planet’s biggest challenges.”

Ploy holds BA and MSci degrees in natural sciences (chemistry) from the University of Cambridge, and MA and PhD degrees in atmospheric and climate sciences from Harvard University.
