Bioinformatics

*Lecturer: Dr P. Liò*

*No. of lectures:* 12

*Suggested hours of supervisions:* 3 (1 example class will be provided)

### Aims

This course focuses on algorithms used in Bioinformatics and System Biology. Most of the algorithms are general and can be applied in other fields on multidimensional and noisy data. All the necessary biological terms and concepts useful for the course and the examination will be given in the lectures. The most important software implementing the described algorithms will be demonstrated.

### Lectures

**Introduction to biological data:**Bioinformatics as an interesting field in computer science.**Dynamic programming.**Longest common subsequence, DNA, RNA, protein structure alignment, linear space alignment, heuristics for multiple alignment.**Sequence database search.**Blast, Patternhunter.**Phylogeny - parsimony-based.**Fitch, Wagner, Sankoff parsimony.**Phylogeny - distance-based.**UPGMA, Neighbour Joining.**Clustering.**K-means, Markov Clustering algorithm.**Markov properties and applications of Hidden Markov Models.****Searching motifs in sequence alignment.**Gibbs sampling.**Biological networks:**reverse engineering algorithms and dynamics; Gillespie.

### Objectives

At the end of this course students should

- understand Bioinformatics terminology;
- have mastered the most important algorithms in the field;
- be able to work with with bioinformaticians and biologists;
- be able to find data and literature in repositories.
