Staff Profile – Samantha Reese

Sam Reese

Clean Energy Manufacturing Analyst
Joint Institute for Strategic Energy Analysis

Samantha Reese spent years traveling the country and world working within various supply chains—from optical communication equipment to data storage. Now she studies the supply chains of clean energy technologies such as wide bandgap semiconductors and geothermal systems at NREL.

"I love being able to connect advancements in basic science to industry through cost and supply chain analysis. At the end of the day, no matter how awesome a technology is, it won't be adopted if it's not cost-competitive."
