Prof Stephen Parker
Profile
The focus of our research is in developing and applying novel computer simulation techniques to extend our understanding of the structure, stability and reactivity of ceramics and minerals at the atomic level. There are broadly three main areas where we apply these techniques, firstly the structure and stability of solid surfaces, secondly chemical reactions occurring at solid surfaces and finally, the modification of crystal structures.
Research Interests
- Computer Simulation of Surfaces
- Predictive Modelling of the Structure and Reactivity of Catalysts
- Computer Simulation of Ceramic and Mineral Crystal Structures
