Bryan E. Tiedemann, Ph.D.

Bryan Tiedemann is a process chemist and chemical engineer with over a decade of experience working in the chemical industry. Bryan graduated from Caltech with a Bachelor’s of Science degree in Chemical Engineering, and from UC Berkeley with a Ph.D. in Chemistry. He worked in ExxonMobil’s Global Basic Chemicals Technology division in Baytown, TX for 10 years, specializing in Olefins technology and supported a global fleet of steam crackers (ethylene plants). He also worked at Shell as a Process Chemist in the Deer Park, TX manufacturing facility supporting Light and Heavy Olefins, as well as Aromatics and Phenol-Acetone. While working at the startup Momentum Technologies, Bryan set up a research laboratory to develop a membrane-supported hydrometallurgy process to recycle lithium ion batteries.
