David Keffer

David Keffer, a professor in the Department of Chemical and Biomolecular Engineering, was recently awarded a distinguished lectureship by the Fulbright Commission. He will spend 10 months in Seoul where he will study different perspectives on sustainability in Korean urban areas.

Keffer directs UT’s Sustainable Technology through Advanced Disciplinary Research (STAIR) program. STAIR is an interdisciplinary Ph.D. program in which students develop expertise in certain sustainable energy areas.

Keffer also established and leads the UT Computational Materials Research Group, which is researching the properties of nanostructured materials—i.e., materials with order on the length scale of one billionth of a meter. Using a variety of computational tools, the group studies polymers under flow, proton transport in fuel cells, lubricant design, reactive molecular dynamics, and other topics.

The research of David Keffer is featured in the Selected Works Author Gallery of Trace, UT’s digital showcase and archive.
