Yuliya Preger is a Senior Member of Technical Staff in the Energy Storage Technology and Systems Group at Sandia National Labs. She earned her PhD and BS in Chemical Engineering from the University of Wisconsin-Madison and MIT, respectively. Her current work is centered on the safety and reliability of Li-ion and aqueous batteries for grid-level energy storage applications. Her research interests include battery cell level degradation and abuse response, application of power electronics to energy storage safety, using battery data for improved energy storage modeling, and system level energy storage safety. She is co-founder of batteryarchive.org, the first public repository for easy visualization and comparison of lithium-ion battery degradation data across institutions.
