In general biological science students have an inadequate in computing and mathematics to undertake the subsequent modules in structural biology. The module is a primer aimed at bringing the students up to the level of mathematics and computation required for the modules that follow in the course. The module is innovative in the sense that it seeks to give the students a grounding in conceptual mathematics by making use of modern computational tools.
Lecturer
Dr David Pugh (Deputy Programme Co-ordinator, UWC) has a background in Applied Mathematics and Physics, and has experience of determining protein structures using nuclear magnetic resonance (NMR) spectroscopy. Dr Pugh is the leader of the Structural Biology Group at UWC. He will also co-ordinate the NMR component of the Masters Programme in Structural Biology, as well as contribute lectures on mathematical techniques and NMR spectroscopy.
Main Outcomes
The aim of this module is to introduce you to most of the physical and mathematical concepts that you will need for the theory modules in the later part of the course. These include complex numbers, vectors and matrices and Fourier analysis. At the same time you will learn the basics of computer programming and gain experience of working in a LINUX environment. For performing numerical and symbolic calculations and displaying the results, you will be using the MATLAB environment. MATLAB also has its own programming language, modelled closely on C, which we will use to do some rudimentary programming. You will also use Perl to write some web-based applications.
