Jacob S. SpendelowJacob S. Spendelow
Los Alamos National Laboratory
“Coaxial Nanowire Electrodes for improved efficiency in water electrolyzers”

Jacob Spendelow is a Scientist at the Los Alamos National Laboratory (LANL). His research focuses on fundamental and applied electrochemical science associated with energy devices such as fuel cells and electrolyzers. This work has included analysis of electrocatalytic processes on model surfaces, development of novel catalysts and catalyst supports for oxygen reduction and oxygen evolution reactions, and design of improved electrode structures and transport media for fuel cells and electrolyzers.

Dr. Spendelow received a BS (2002) and MS (2003) in Chemical Engineering from Case Western Reserve University. He completed a PhD at the University of Illinois at Urbana-Champaign in 2006 with funding from a National Science Foundation Graduate Research Fellowship. Andrzej Wieckowski and Paul Kenis were his advisors. He joined LANL as a Director’s Postdoctoral Fellow in 2006 and became a staff member in 2008, working with the Fuel Cells Team. In addition to his research work, Dr. Spendelow served for several years as a science advisor and program manager at the Department of Energy Fuel Cell Technologies Office, where he managed R&D projects related to polymer electrolyte membranes, catalysts and supports, and reversible fuel cells. He is the recipient of the 2019 Hydrogen and Fuel Cell Technologies Office Annual Merit Review Fuel Cell R&D Award.

William TarpehWilliam Tarpeh
Stanford University
“Enabling and implementing a sustainable circular economy using selective membranes”

William Tarpeh is an Assistant Professor of Chemical Engineering at Stanford University. The Tarpeh Lab develops and evaluates novel approaches to resource recovery from “waste” waters at several synergistic scales: molecular mechanisms of chemical transport and transformation; novel unit processes that increase resource efficiency; and systems-level assessments that identify optimization opportunities. His ECS Toyota Young Investigator project focuses on designing solute-selective membranes for lithium and other critical battery materials (e.g., nickel, cobalt).

Dr. Tarpeh completed his BS in Chemical Engineering at Stanford in 2018. His MS (2013) and PhD (2017) in Environmental Engineering at the University of California, Berkeley were supported by an NSF Graduate Research Fellowship, Ford Foundation Predoctoral Fellowship, and UC Berkeley Chancellor’s Fellowship.

2022–2023 ECS Toyota Young Investigators Fellowships

The Fellows each receive a $50,000 grant to conduct the research outlined in their proposals and a one-year complimentary ECS membership. They submit a midway progress report to ECS and, after one year of funding, a final written report. TRINA invites them semiannually to present their research progress. Their findings are published open access in a relevant ECS journal, and within 24 months of the end of the research period, and presented at an ECS meeting. Toyota may choose to enter into a research agreement to continue working with the Fellows after their fellowship’s end.
