General information

BIG ( was the first research unit in Armenia to deal with the computational challenges of genomics. It’s been focused on the development and application of algorithms and software for “-omics” data analysis, as well as molecular networks and pathways to facilitate the discovery of molecular mechanisms of complex diseases. The group has developed the Pathway Signal Flow algorithm (PSF) that provides quantitative measures of pathway activity based on gene expression data, software for the extraction of topology information from the KEGG pathways (KEGGParser and CyKEGGParser), software (Computel) for the calculation of telomere length from WGS data, which is currently one of two most cited software tools for telomere length calculations worldwide. Cancer genomics is one of the focus areas of BIG research, in particular, multi-omics analysis of lung, colon, brain, and blood cancers.
