Biography

Linda Jewell is currently a Professor of Chemical Engineering at Unisa.

Her PhD (Wits, 1996) focused on heterogeneous catalysis and was followed by a postdoctoral fellowship at the Centre for Applied Energy Research in Lexington, Kentucky. She then spent two years working in the industry before her appointment at Wits as a senior research officer. She became a senior lecturer in the School of Chemical and Metallurgical Engineering at Wits in June 2004 and was promoted to associate professor in October 2010. She joined Unisa in January 2013 to take up the position of Chair of Department of Civil and Chemical Engineering; she held this position for six years. She was promoted to Professor of Chemical Engineering in 2015.
