Biometry and bioinformatics II


Sirkka-Liisa Varvio

Scope, type and prerequisites

  • 5-10 cr. Assignments given at the beginning of the course is the 5 cr part of the course, and extension 5 cr -> 10 cr is by doing more assignments.
  • In statistics curriculum: intermediate / advanced studies.
  • Prerequisites: At least intermediate level of probability and statistical inference courses and basic familiarity to working with sequence data (such as provided by the course Biometry and bioinformatics I, for example). The spirit of the course is learning by doing assignments.

Short description of contents

The ultimate goal is to provide understanding of life through molecular information, via statistical and computational analyses. Models of molecular evolution and phylogeny inference, going further from the basics which were in the course Biometry and bioinformatics I: maximum likelihood, bayesian and network inference. Past, or traditional, practice on phylogenetics has been to describe relationships among species within the disciplines systematics and taxonomy. Today the scope is much wider. Phylogenetics is used as a necessary tool in all kind of bioscience research questions: relationships among genes, gene families, alleles, cell lines, various genomic components, histories of populations, evolutionary and epidemiological dynamics of bacteria and viruses, etc.  Phylomics is the natural extension of genomics and metagenomics, phylotyping the current way of understanding ecosystems within and outside organisms (environments) and evolutionary thinking is a complementary framework to medical genetics. Statistical and computational approaches, based on predictions derived from population genetics theory, aim at dissecting neutral (stochastic) and selected (darwinian natural selection) components of genetic diversity.

Time schedule

The first session will be Tuesday 4.11, 14-17, computer class C128  (not 28.10 as the exam of  Biometry and bioinformatics I is still going on).
The assignments for 5-10 cr part of the course will be launched during the sessions 4.11 and 11.11. Working after these two common sessions can accomplished according to personal, and negotiable, time schedules. There will be no exam. Grading is based on the quality of assignments and pass/fail is also possible. 

Lecture material and scientific publications


You can choose which assignments you perform. Assignments 1, 2, 3 and 4 are 1 cr, each, assignment 5 will be 1-3 cr (depending on the amount of work you want to do). In addition, there will be essay topics (1 cr = 5 page essay about a topic, Assignments 6). You can also tailor a molecular evolutionary project for yourself about an interesting gene, or some other genomic compartment.
