As such, most entry-level workers in medicinal chemistry, especially in the U.S., do not have formal training in medicinal chemistry but receive the necessary medicinal chemistry and pharmacologic background after employment—at entry into their work in a pharmaceutical company, where the company provides its particular understanding or model of «medichem» training through active involvement in practical synthesis on therapeutic projects. (The same is somewhat true of computational medicinal chemistry specialties, but not to the same degree as in synthetic areas.) Hence, although several graduate programs offer Ph.D. and postdoctoral training in medicinal chemistry, the broader education of a top-tier synthetic or physical chemistry graduate program most frequently provides the entry level skills sought for industrial medicinal chemistry.
