Teaching activities

Teaching activities are held in form of graduate courses as well as annual courses in collaboration with some European experts. Our teaching is compliant with the guidelines of Bologna convention and we extensively use distance-learning methods. We have one introductory course – Bioinformatics, while the rest of the courses are a part of Computational biology module for studding advanced bioinformatics tools and methods.

Communication with students and distribution of course materials are accomplished through our bioinformatics eduactional portal, BEPo. The portal is based on the “Moodle” e-learning system and has been in use for over a decade.

Students work in groups and with assistance from professor and assistants perform research on specific topics.

While going through their projects, students search biological databases to investigate epidemiology, genetics and molecular mechanisms of he disease. After literature search, students search sequence databases and learn to manipulate with sequence information using different bioinformatics tools to acquire further information. Students complete their projects by preforming phylogenetic analysis and calcification and visually presenting their results.
