Biomathematics Sequence
This cross-disciplinary sequence provides students with a unique and strong cross-disciplinary training in biology and mathematics. The sequence is designed first to give students a solid foundation in mathematics (core courses), then training in one of two biological areas that use specific types of mathematical applications to address biological questions (emphases). Before entering the sequence, students should have two semesters of calculus and one semester of linear algebra.
This 32-hour sequence requires:Ìý
- 2 hours of Ìý
