Dr. Ilias Lagkouvardos is a microbial ecologist and data integration enthusiast who utilizes bioinformatic methods and tools to address questions related to microbial diversity and ecology in various environments. The primary focus of his research group is the elucidation of the role of distinct microbial compositions in human health and disease by means of sequencing of the versatile 16S rRNA gene.  In addition, he explores microbial genomics and metagenomics sequences for insights into the functionality and dynamics of complex microbial communities.

One main line of research in the Lagkouvardos group is to utilize state-of-the-art methods and tools to build specialized analytical pipelines and thereby develop user-friendly bioinformatic solutions for public use. One example of such novel bioifnormatic tool is the IMNGS platform (, a web database that automatically retrieves all publically available 16S rRNA gene amplicon sequences and processes them in a uniform and organized way. The group also released Rhea, a set of R scripts for the analysis of microbial profiles ( Courses disseminating expert knowledge on sequence analysis and demonstrating the usability of these tools are organized regularly.
