Kurabachew S Duba


Postdoctoral Researcher, Duke University

Kurabachew (Kura) moved from the University of Trento, Italy to Duke to work as a postdoctoral associate. At University of Trento, he conducted research at the Green Process Engineering Research Group on supercritical technologies for the valorization of agro-industrial by-products. Prior to that, he was a lecturer in Ethiopia at Bahir Dar University, Institute of Technology where he taught undergraduate courses in Chemical Engineering. His research interests lie in the application of supercritical fluids (CO2 & water) for the environmental remediation, recycle, recovery & reuse of by-products, water/waste-water treatment, waste to energy and energy integration.

Some of his peer-reviewed journal articles include:
