Description: Aims:
To introduce students to applications of partial differential equations to model problems arising in biology. Both mathematical modelling and mathematical analysis will be covered, and at all times the interplay between the mathematics and the underlying biological concepts will be emphasised.

Learning Outcomes:
At the end of this unit, students should be able to:
* Derive and interpret mathematical models of problems arising in biology using partial differential equations
* Analyse models written in terms of partial differential equations
* Give a qualitative and quantitative account of their solution, and
* Interpret the results in terms of the original biological problem
* Discuss the ideas presented in this unit orally to demonstrate in-depth understanding of the material.

Skills:
Mathematical modelling in biology T/F A
Problem solving T/F A
Written communication F A
