Associate Professor, Mechanical Engineering
Dr. Steven DeCaluwe’s research interests center on clean energy and water systems, with a focus on electrochemistry and interfacial processes. He leads the CORES Research Group, which combines fundamental experiments with numerical simulations to study the chemical, thermodynamic and fluid mechanic processes occurring at material interfaces and in reacting flows. Via fundamental insight into these processes, technologies can be designed and improved to enhance the quality of life for diverse populations and ease the impacts of human resource use on critical ecosystems and habitats across the globe.
Dr. DeCaluwe joined the Department of Mechanical Engineering in 2012 following an NRC postdoctoral fellowship at NIST in Gaithersburg, Maryland. His work at NIST used neutron scattering experiments to study solid electrolyte interphase formation in lithium-ion batteries and water uptake in thin-film polymers for PEM fuel cells.
Dr. DeCaluwe has a PhD from the University of Maryland, College Park. His dissertation was titled “Quantifying the role of ceria as catalyst in solid oxide fuel cell anodes.” His work at UMD involved electrochemical experiments, in operando physical chemistry diagnostics and multiscale simulations.
Dr. DeCaluwe holds a BS in Elementary Education and Mathematics from Peabody College at Vanderbilt University. For three years prior to attending graduate school, he taught first and second grade in Nashville, Tennessee.
