BioThe availability of low-cost but intermittent renewable electricity (e.g., derived from solar and wind) underscores the grand challenge to store and dispatch energy so that it is available when and where it is needed. Redox-active materials promise the efficient transformation between electrical, chemical, and thermal energy, and are at the heart of carbon-neutral energy cycles. Understanding design rules that govern materials chemistry and architecture holds the key towards rationally optimizing technologies such as batteries, fuel cells, electrolyzers, and novel thermodynamic cycles. Electrochemical and chemical reactions involved in these technologies span diverse length and time scales, ranging from Ångströms to meters and from picoseconds to years. As such, establishing a unified, predictive framework has been a major challenge. The central question unifying our research is: “can we understand and engineer redox reactions at the levels of electrons, ions, molecules, particles and devices using a bottom-up approach?” Our approach integrates novel synthesis, fabrication, characterization, modeling and analytics to understand molecular pathways and interfacial structure, and to bridge fundamentals to energy storage and conversion technologies by establishing new design rules.

Ryan Coffee
Senior Scientist, SLAC National Accelerator Laboratory
BioRyan earned his Bachelor of Arts in Philosophy and Bachelor of Science in Physics from the University of Arkansas followed by a PhD in Atomic, Molecular and Optical (AMO) Physics from the University of Connecticut. He joined the PULSE Institute at Stanford/SLAC in 2006 and led the first laser pumped, x-ray probed experiment at the Linac Coherent Light Source (LCLS) in 2009. Since then, he has become Senior Research Scientist in PULSE and LCLS with an emphasis on AMO science and novel instrumentation and the requisite computational methods for streaming data processing at the sensor edge, in particular targeting the million frames per second LCLS-II.
In that context he has been a core member of the SLAC AI Initiative since its inception with particular emphasis on Machine Learning for real-time information extraction. With projects ranging from x-ray spectroscopy in molecules, ultrafast materials response, radiographic medical imaging, and tokamak plasma fusion, he has become an adamant proponent of data and model marketplaces for cross-domain innovation sharing with built in provenance and value tracking for an intelligent adaptive data and model retention.
Beyond SLAC, Ryan is driving an integrative approach to instrumentation and co-design of computing infrastructure across the portfolio of Department of Energy labs and facilities as well as technologies across the computing industry. From diagnostic and detector development to algorithms and AI accelerators, from the sensor Edge to Leadership Computing Facilities, he is leveraging his hobbies and his passions to drive the bleeding edge of basic science to address the emerging challenges of automation in industry and agriculture for a better future for his daughters.
