Information for international students

 The course in lectured in English.



  • The course has been graded. See results here.
  • Please provide feedback on the course here.


Introdoctory course in bioinformatics (e.g. Algorithms in Bioinformatics, Computational genomics) or equivalent knowledge. 

Main themes

The course explores computational methods (algorithms, probabilistic models, machine learning) in two main themes:

  1. Gene prediction, regulation, RNA life (Lectures on weeks 1-2, groupwork on week 3, exercises on weeks 2-3)
  2. Protein structure, function and networks (Lectures on weeks 1-2, groupwork on week 3, exercises on weeks 2-3)


Kurssin suorittaminen

 The course can be completed in two primary ways:

  1. Lectures, exercises, group work and course exam
  2. Separate exam (first opportunity February 3, 2012)

Grading of the course


The course has three components that contribute towards the grade

  1. Exercises (30%) of the grade. Exercises are completed at home and returned in writing prior to the exercise session to Esa Pitkänen (esa.pitkanen at cs.helsinki.fi)
  2. Group work (20%) of the grade. Two groupwork assignments are completed during the course (3. and 6. week of the course, instead of lectures). The groupwork entails studying a given topic together and preparing a short presentation.
  3. Course exam (50%) of the grade. Course exam will be on Tuesday December 13, at 9.00am. Examined contents are the lectures and exercises.
