Summary
🤩
Rockstar🎓
Top SchoolAlec Bills is a founding engineer and battery modeling specialist with seven years of experience bridging academic research and startup product development. He holds a PhD in Mechanical Engineering from Carnegie Mellon and has applied advanced physics-based modeling at companies like Cuberg and in open-source projects such as PyBaMM, where he contributed backend work on discretization, solution methods, and processed variable handling. Based in Oakland, Alec excels at turning complex electrochemical models into robust, production-ready code and has hands-on expertise in explicit time integration and model processing for experiments. He combines deep simulation skills with practical engineering from internships at Gulfstream to industry-facing roles, making him equally comfortable in research, code, and product contexts. An understated strength is his track record of improving model-building reliability in collaborative open-source environments, helping teams accelerate battery R&D.
