Learning objectives
The course aims to provide students with the principal techniques used in the modeling of biological macromolecules. Both the general principles of the most important approaches and their applications to biologically and pharmaceutically relevant systems, such as enzymes, receptors, polypeptides, protein-protein and ligand-protein complexes, will be discussed.

Prerequisites
Basic knowledge of math, physics, physical and organic chemistry

Assessment method
Oral exam. The exam will consist of a discussion which aims to verify the preparation of the student on the course contents. The examination will typically include a few questions concerning both basic simulation methods and their applications to the study of biomolecules.
