Research Interest
The research interests are focused on plant, animal and human genomics and bioinformatics including basic and applied research:

  • Development of the molecular marker systems such as microsatellites (MSs), SNP-markers (single nucleotide polymorphisms) and genome mobile elements (transposons and retrotransposons) in cereals, mainly barley and farm animals (cows and others);
  • Evaluation of the genetic diversity in wild and cultivated barley and farm animal populations based on molecular marker genotyping and haplotype analysis;
  • Application of marker assisted selection (MAS) in barley and farm animals breeding programs;
  • New polymorphism detection in candidate genes for the economically important traits in barley and cow based on genomic DNA sequencing;
  • Identification and characterization of the genomic sites involved in nuclear rearrangements during barley plant development;
  • Association study on candidate-gene polymorphisms, cardiovascular, autoimmune and metabolic disorders in humans.
