Pistorius' work focuses on metal production and processing, including energy requirements and efficiency of ironmaking, steelmaking and titanium production.

Dr. Pistorius received his bachelor's degree in Metallurgical Engineering from the University of Pretoria in 1987, his master's degree in Metallurgical Engineering from the University of Pretoria in 1988, and completed his Ph.D. in corrosion at the University of Cambridge in 1991. He was an Associate Professor and then Professor in the Department of Materials Science and Metallurgical Engineering, University of Pretoria, South Africa, from 1991 to 2008; he served as Head of that department from May 2002 to June 2008. He is a Member of the Academy of Science of South Africa, and a Fellow of the South African Academy of Engineering.


Ph.D., University of Cambridge


Dr. Pistorius conducts research in the Center for Iron and Steelmaking Research, focusing on steel cleanliness, reaction kinetics, ironmaking, and electrochemistry. As a member of the NextManufacturing Center, Dr. Pistorius studies porosity measurement and prediction in additively manufactured (AM) metal components.
