The bioinformatics group is dedicated to the development of efficient computational methods for important real-world biological and medical problems. The projects cover a diverse range of exciting topics from analyzing metagenomic sequencing data, to gene expression analysis and metabolomics.
The group is based at the Computer Technologies Department at ITMO University and supported by JetBrains. The group actively collaborates with Maxim Artyomov’s laboratory at Washington University in St. Louis and Dmitry Alexeev’s laboratory at MIPT.
Main research projects
Algorithms for comparative metagenomics
Metagenomic projects usually deal with a lot of data: up to several hundred gigabytes of sequencing data per project. To be able to effectively analyze such amounts of data and perform a comparative analysis, a software called MetaFast was developed. It implements a lightweight assembly algorithm which is something between traditional k-mer spectrum analysis and full metagenomic assembly. The algorithm allows MetaFast to combine the advantages of both methods: high computational performance with more informative and better interpretable extracted features, all without using reference genome sequences.
Analysis of open gene expression databases
Currently, there are several big databases, such as TCGA and GEO Omnibus, which store the data from a huge number of experiments. Analyzing these experiments and finding hidden interrelations is a very promising field. As part of the project, a web-service GeneQuery is being developed, which allows experiments with similar patterns of gene regulation to be found. Using the results of such a search can lead to the discovery of unobvious connections, which can also then facilitate hypothesis generation.
Computational methods for studying metabolic regulationRecently a metabolic regulation role was recognized as one of the immune systems and cancer hallmarks. In this project, a number of methods are being developed to analyze gene expression and metabolomics data to study such regulation. Currently, some of the methods are available as a web service GAM for integrative network analysis of gene expression and metabolomics profiling data.
