Description

This course is designed to provide a basic introduction to computational methods used in protein structure determination and molecular modeling. The course emphasis will be on the use of computational methods for protein structure prediction to understand protein structures through modelling and on structure based drug design. The course will provide practical training in the application of modeling techniques in drug discovery
