Dr. Chang is a computational economist whose work focuses on computational methods in decision analysis, with applications in energy systems modeling, macroeconomic impact analysis of environmental and energy regulations, and large-scale stochastic analysis.

As a market modeling expert, Dr. Chang provides model-driven solutions to address key uncertainties in energy markets. He has led workshops for utilities and regional transmission organizations in simulating market uptake of energy storage resources under new market rules, and has supported long-term business planning for numerous US electric utilities regarding the uncertain market adoption of customer-owned electricity generation resources.

Dr. Chang has authored numerous policy reports that provide economy-wide market impact assessments of regulatory shocks, such as the International Maritime Organization’s 2020 regulation for a 0.5% sulfur cap on marine fuels and a potential bipartisan climate legislation to cut emissions using a carbon dividends plan. He has previously led workshops for the European Union on modeling the economic impacts of emissions trading schemes.

Prior to his career in economic consulting, Dr. Chang was an economist at Pacific Northwest National Laboratory, conducting macroeconomic modeling for the US Energy Information Administration’s International Energy Outlook. He is currently a lecturer in the Department of Economics at University of Maryland, College Park, where he teaches Microeconomics in the Masters in Applied Economics program.
