Scott A. Barnett is a Professor in the Materials Science and Engineering department at Northwestern University in Evanston, Illinois, USA.

After receiving his Ph.D. in Metallurgy from the University of Illinois at Urbana-Champaign in Metallurgy in 1982, he held postdoctoral appointments at the University of Illinois and Linkøping University (1983-6). He took his present position at Northwestern University in 1986, and has also been a Fulbright Guest Professor at Centro Atomico Bariloche (2016), Otto Mønsted Guest Professor at the Danish Technical University  (2013), Cheng Tsang Man Endowed Professor at Nanyang Technological University (2009), and a Visiting Scientist at Los Alamos National Laboratories (1998).  He served as the founder and Chief Technical Consultant of two companies:  Functional Coating Technology LLC (2001 – 2011) and Applied Thin Films Inc (1998-2001).  He has authored or co-authored > 300 publications, has 15 patents, and has advised nearly 50 PhD students.  Research topics have included semiconductor growth by molecular beam epitaxy, ion-assisted thin film deposition, nitride hard coatings and superlattices, solid oxide fuel cells and electrolyzers, Li-ion battery cathodes, and electrode characterization via three-dimensional tomography. He is an Electrochemical Society Fellow, AVS Fellow, and was an Office of Naval Research Young Investigator.  He has actively participated in ACerS meetings for many years and has been on the Program Committee of the International Symposium on Solid Oxide Cells (SOC): Materials, Science and Technology (part of annual ICACC meeting) for the past several years.

Current research interests include development and characterization of novel electrode materials, energy storage using SOC and Li-ion batteries, and accelerated testing to characterize cell degradation processes.
