The Energy Technologies Area (ETA) is unique in translating fundamental scientific discoveries into scalable technology adoption. Our approach combines an understanding of the marketplace and the role of state and federal regulation and policies. ETA’s research drives real-world, practical results that affect and improve the everyday lives of Americans and those across the globe. Saving energy and battling the Climate Crisis are key to the foundation of our research, which is driven by techno-economic analysis and in-lab experimentation and discovery.

The Physical Sciences Area seeks to understand the fundamental physics of the universe at scales ranging from the infinitely small, inside the world of subatomic particles and nuclei, to the infinitely large, in the structure and evolution of the universe. To tackle these two infinities, we develop cutting-edge tools and technologies, coupled with creative scientific insights, that advance scientific knowledge and ultimately benefit society.

The core mission of the Heavy Element Chemistry (HEC) program is to pioneer innovative experimental approaches and perform basic research in actinide and transactinide chemistry, to understand and control at a fundamental level bonding, physical properties, and reactivity of the heavy elements across multiple-length scales, with a particular focus on the roles of f electrons and orbitals. Accompanying this core mission is the education and training of future scientific leaders in the field.
