Ulf Österberg

Ulf Österberg

Visiting Professor of Engineering

Overview

Born and educated in Sweden. Post-docs in the USA in the field of nonlinear optics in glasses for the purpose of high bandwidth data transmission in optical fibers. Later research focussed on ultrafast and THz spectroscopy in condensed matter. Deeply involved with teaching pedagogy and novel forms of classroom instruction.
