Matthieu Dubarry (PhD, Electrochemistry & Solid-State Science, University of Nantes), has over 20 years of experience in renewable energy, with an emphasis in the area of lithium-ion batteries.

Following his PhD on the synthesis and characterization of materials for lithium batteries, Dr. Dubarry joined the Hawai‘i Natural Energy Institute at the University of Hawai‘i at Mānoa as a post-doctoral fellow in 2005 to work on the analysis of the usage of a fleet of electric vehicles. He was later appointed a faculty position in 2010 with a focus on battery testing, modeling and simulation. He is now a tenured Associate Researcher and has been leading his own group since 2014 with funding from both federal and industry sources. In 2025, he was awarded the University of Hawai‘i Regents’ Medal for Excellence in Research.

While working for HNEI, Dr. Dubarry pioneered the use of data-driven techniques for the non-destructive analysis of the degradation of lithium-ion cells and developed numerous software tools facilitating the prognosis of battery degradation both at the single cell and the battery pack level. His model, ʻalawa (Hawaiian for “to diagnose with insight”), received significant accolades from the community and is used worldwide both by universities and industry.

Current projects include further development of the ‘alawa framework, the testing of emerging battery technologies, both lithium and sodium based for grid-connected and transportation applications, and the evaluation of sodium ion intercalation materials for desalination batteries.
