The head of the Genomics and Bioinformatics Center of the Comenius University Science Park in Bratislava and the scientific director of the biotechnology company Geneton professionally specializes in DNA sequencing technologies, i.e. DNA reading. Since 2006, the main area of ​​his research has become the so-called free circulating DNA, more specifically circulating fetal DNA in pregnant women and circulating tumor DNA in the blood of oncology patients. He is the co-author of the NIPT clinical test (Non-invasive prenatal test) for the detection of chromosomal and subchromosomal disorders of the fetus, which has been used in clinical practice for 10 years under the commercial name Trisomy test in several EU countries. In the years 2004 - 2014, he was a member and later the head of the sequencing core laboratory for 1st generation sequencing called BITCET. He is a member of the professional societies ESHG, EHTG, F1000 (Faculty 1000), as a specialist in prenatal diagnostics. He was a member of the working group of the Pandemic Commission of the Ministry of Health of the Slovak Republic for the genomic sequencing of clinical samples of the SARS-CoV-2 coronavirus, while he fundamentally succumbed to .
