Course description: Mathematical and quantitative modeling of biological phenomena has become a necessary approach at studying living organisms. Mathematical biologists work towards identifying unified frameworks that describe biological phenomena in different levels of complexity. It ranges from small entities such as viruses and bacteria, cells in tissues and, ecological models where animals compete for resources in a habitat. This course introduces basic concepts of mathematical biology with modern applications in mind. We use dynamical systems tools to model mechanisms of cell growth and cell- cell interaction as well as complex evolution of species. We discuss subjects such as microbial growth, cancer evolution and virus dynamics and epidemiology.

Course time: 2020 Winter 2A (2:25-4:15)

Course Location: Kemeny 004

Instructor: Kamran Kaveh

(Office: Kemeny 244, Email: kkaveh@dartmouth.edu)

Prerequisites: Math 3. Familiarity with programming (for example: MATLAB, Python or Mathematica). Basic probability highly recommended.

Grading: Projects (50%), Problem sets (40%), Attendance & Participation (10%)

Projects: Approximately 4 weeks are given to complete the project. The instructor will suggest project ideas in the third week, but you are allowed to propose your own, which has to be approved by the instructor in the fourth week at the latest. Each project presentation is limited to 15 minutes and preferably in the style of TED talks.

Late policy: By “deadline” we mean it. On the condition of accepting the penalty for turning in homework late (that is, 5% each additional day), however, an extension of maximum 2 days will be granted on a case-by-case basis.

Collaboration policy: Collaborations on problem sets are permitted, but you are required to disclose the names of the other students with whom you collaborated and discussed. You are encouraged to work in groups for course projects (but no more than 2 individuals per project).

Textbooks: Mainly notes. Useful references are “Evolutionary Dynamics”, M. A. Nowak (2006). “Mathematical Biology”, J. D. Murray (2003).
