Master programs and postgraduate courses in biology are for graduates with bachelor's or master's degree who want to work in the environmental, medical, pharmaceutical sector. They are specialization programs for boys and girls passionate about science, nature, flora and fauna. Students choosing a path of improvement in the biological area usually come from scientific disciplines and want to become researchers or men and women who work in genetics, the study of living organisms, rather than experts in agronomy, botany, zoology.
