Cheminformatics refers to the use of computational and other data handling techniques to derive relationships from large amounts of chemical data. Its most well-known applications are to determine the relationships between structure and properties of compounds to aid in the discovery and synthesis of new pharmaceuticals, and graduates with knowledge in this area are in demand in the pharmaceutical industry, but it has wider applications. A B.S. in chemistry with an emphasis on elective courses in computer science and bioinformatics provides a background for this field.
