PhD student

Supervisor: Konstantin Severinov

Entry Year to Skoltech – 2013

Graduated from Moscow Academy of Veterinary Medicine and Biotechnology with diploma work on the “Isolation of minor enterobacteriophages from animal feces and their characteristics» made in Laboratory of microbial viruses, Institute of Microbiology, RAS (Research group leader Dr. A. Letarov).

Research project: The mechanisms of adaptation and interference in CRISPR/Cas system against a variety of virulent phages with different strategies of infection.

In Escherichia coli, the acquisition of new CRISPR spacers is strongly stimulated by a priming interaction between a spacer in CRISPR RNA and a protospacer in foreign DNA. This phenomenon, which we refer to as “priming”, can be used for very simple and rapid construction of multiple E. coli strains capable of targeting, through CRISPR interference, any phage or plasmid of interest. Availability of such strains should allow rapid progress in the analysis of CRISPR-Cas system function against diverse mobile genetic elements.
