As a university lecturer and forensic geneticist, my research focuses on DNA polymorphisms (SNP, microsatellite and VNTR elements, mitochondrial genome). By analysing these variable genetic elements, it is possible to identify a taxon (species) at the molecular level, and to identify and verify the relationships between individuals within the taxon. Determination of allele frequency values of variable loci in populations can be utilized in population and evolutionary genetics as well as is essential in forensic genetic applications. One of the main area of my current research is to determine sequence variants of human microsatellite (STR) loci by next-generation DNA sequencing in the Hungarian populations. Another main focus is to extend the investigation of eDNA and non-human biological traces for forensic genetic purposes. For this reason we develope in my group original eDNA sampling methods and we extend their analytics to metagenomic DNA sequencing on mixed biological samples as well. The identification of different species from mixed sources induce both biological and statistical/probability issues, requiring the development and validation of Bayesian approach methods based on probability ratio testing.
