David (Dave) Eaglesham brings expertise in technology development, commercialization, management, and investment to EnPower as a Technical Advisor. 

Currently, Dave is Entrepreneur-In-Residence at Breakthrough Energy Ventures, the $B Venture fund for Climate Change founded by Bill Gates, where he is leading sector assessments in Hydrogen and related technology opportunities. 

He was previously CEO at Pellion Technologies, an early-stage VC-backed battery company, which he brought from earliest concept to successful launch of the world’s only 1000Wh/L rechargeable product. 

Prior to Pellion, Eaglesham was Chief Technology Officer at First Solar, the world’s most successful startup in photovoltaic (PV) technology, where he helped drive cost/W from $1.90 to $0.54, while improving efficiency from 9% to 14%. He has also played executive leadership roles at Applied Materials Lawrence Livermore National Labs, Agere Systems, and Lucent Technologies. At Bell Labs he worked on implant, epitaxy, and electron microscopy, where he helped to bring a number of key novel technologies all the way to high-volume manufacturing, and was ultimately VP of Electronic Device Research. 

He was named Outstanding Young Investigator by the Materials Research Society (MRS) in 1994, and was President of the MRS in 2005. Eaglesham earned a BSc in Chemical Physics and a PhD in physics from the University of Bristol and achieved tenure as a Lecturer at Liverpool University. He is a fellow of the American Physical Society.
