We are a team of bioinformatics researchers at the Institute of Molecular Biology, that develops and provides creative solutions to high-throughput biological data analysis. Our lab members are experienced in various aspects of bioinformatics and computational biology: starting from raw data processing, ending with systems biology level analysis, as well as with bioinformatics software development.

Our group is engaged in research projects aimed at secondary analyses of publicly available datasets to reveal the mechanisms of development of complex human diseases. On one hand, we develop novel algorithms, approaches and software for efficient knowledge inference from gene expression and sequencing datasets. On the other hand, we use existing tools to perform actual biological research. We have more than seven years of experience in pathway-based analysis of high-throughput gene expression data, particularly using the pathway signal flow algorithm developed in our group. Another research direction at focus is telomere bioinformatics: development and application of novel computational approaches for analysis of telomere length dynamics and telomere maintenance mechanisms from gene expression/DNA sequencing data. These, and other interests of our group are reflected in the following publications, and described at our website (http://big.sci.am/).

  • Positive review for Bioinformatics Data Analysis:

    February 2019

    "The team at the Institute of Molecular Biology NAS RA provided excellent bioinformatics analysis for us. They recommended an approach that was unique to us among the service providers that we engaged with previously inside and outside the Science Exchange, and ultimately their methods delivered novel insights and leads on biological mechanism. The team was responsive, professional, timely, and thorough in the delivery of the work."
