A group of four bioinformaticians and molecular biologists: Izabela Makałowska (PhD, Professor), Michał Szcześniak (PhD), Joanna Ciomborowska (PhD) and Michał Kabza (M.Sc.). They are constantly striving to improve their knowledge in various bioinformatics subjects and other life sciences, including experimental biology. They attend scholarships in international academic institutions and specialized courses or conferences. At the same time they conduct intensive research and the results of their work are published in reputable scientific journals. First of all, they are organizers and teachers during plenty of bioinformatics courses aimed mostly to PhD students and young researchers in order to expand their knowledge and skills. These courses are related to wide range of subjects connected with NGS data analyses, basics of bioinformatics, statistics, programming for biologists, as well as creating biological databases. They are also involved in PSSB Poznan Summer School of Bioinformatics -biennial international event held in Poznan, focused on most up-to date issues in current bioinformatics. Last edition in 2015 covered subjects like next-generation sequencing of transcriptomes (RNA-Seq), small RNAs discovery, long non-coding RNAs as well as secondary and tertiary structures of RNA molecules. All their courses are suitable both for beginners and for those who already have some basic knowledge in bioinformatics and want to learn more about bioinformatics applications in their studies. Courses consist of lectures and hands-on - this combination should fit best researchers needs as they have a chance to try out the discussed methods on your own. Moreover, i4b performs next generation sequencing data analyses in some scientific projects, including close cooperation with UMB in STRATEGMED2 funded by the National Centre for Research and Development (project called MOBIT).
