Biography:
| Dr. Stefan Lohfeld is a senior research engineer at the NCBES, NUI Galway. He obtained his German Diploma in Production Engineering (comparable to Masters Degree in Ireland) at the University of Bremen. He then went on to the Karl-Winnacker-Institut der DECHEMA e.V. in Frankfurt, Germany, to perform his research on high temperature oxidation of intermetallic phases and received his PhD degree in the area of materials science from the Rheinisch-Westfälische Technische Hochschule (RWTH) in Aachen, Germany. In 2002 Stefan joined the NCBES at NUI, Galway to work on an Enterprise Ireland RIF project. Subsequently, he managed the research activities at NUI Galway for the "STEPS" EU FP6 project and manufactured bone tissue engineering scaffolds using rapid prototyping techniques. He received funding from the Enterprise Ireland Commercialisation Fund for two subsequent projects on the development of a novel implant to replace damaged cartilage. His
early research efforts were focused on materials of several groups and
he is experienced with mechanical testing and the materials behaviour in
corrosive and oxidising media as outlined below:
- mechanical testing of ceramic and polymeric compounds
- heat treatment of titanium and titanium alloys in nitriding atmospheres
- corrosion behaviour of screw joints for magnesium and aluminium parts
- characterisation of thermal barrier coatings for gas turbines
- high temperature oxidation behaviour of reinforced intermetallic phases
