Haewon McJeon

Integrated Modeling & Energy


Haewon McJeon is a staff scientist at the Joint Global Change Research Institute, a partnership between the Pacific Northwest National Laboratory and the University of Maryland. His research focuses on developing methods for decision-making under uncertainties surrounding climate change. Dr. McJeon's recent work has examined large-scale technology combinations and their impact on the cost of climate stabilization, the climate implications of globally abundant natural gas, and long-run energy-emission scenarios for the next three centuries.
