Roy L. Johnston Ph.D.
Since 1990, I have been actively involved in research in a number of areas of theoretical chemistry: modelling the structures growth and dynamics of elemental, molecular and nanoalloy clusters; studying metal-insulator transitions in macroscopic and microscopic systems; applying Genetic Algorithms to optimization problems in chemical physics; theoretical studies of the electronic structures of inorganic and molecular solids.Research Interests
- Theoretical Chemistry
- Simulation of Solids, Surfaces and Clusters
- Modelling Cluster Growth and Dynamics
- Structures, Segregation and Dynamics of Nanoalloy Clusters
- Electronic Structures of Inorganic and Organic Solids
- Applications of Natural Computation (e.g. Genetic Algorithms) in Chemistry
- Theoretical Studies of Protein Folding
My research has led to the publication of over 100 primary research papers. My research group is currently composed of five PhD students and a number of undergraduate project students.
