Dr. Bogart is a licensed professional engineering specializing in batteries and battery systems. He provides consultation on all aspects of the battery life cycle from cell qualification to failure analysis and recall support. He uses his wealth of experience to assist in battery vendor selection, quality of manufacture assessments and factory audits, performance and reliability testing, and safety evaluations for products in multiple industries including consumer and commercial electronics, electric vehicles, energy storage systems, and medical devices.

Dr. Bogart is knowledgeable on a variety commercial batteries including lithium-ion, alkaline, and lead-acid in addition to next generation cell chemistries such as solid-state, lithium metal, and silicon-based batteries.

Prior to joining Ģ��tv, Dr. Bogart led the development of a silicon-based material for lithium-ion battery anodes at Nexeon, Ltd. gaining experience with material production as well as commercial fabrication and testing of batteries. Additionally, he was a National Defense Science and Engineering Graduate Fellow at The University of Texas at Austin where he conducted research focused on the design, synthesis, and characterization of silicon and germanium nanowires for next generation lithium-ion battery anodes.
