Antibiotics are used to treat and prevent bacterial infections. However, the high consumption has resulted in increased prevalence of antibiotic resistance – when bacteria change so that antibiotic treatment is no longer effective – which is one of the major threats to human health today. The changes can occur through mutations in the bacterial DNA or through the acquisition of mobile antibiotic resistance genes. My research focuses on developing methods with applications within clinical diagnostics to analyze whole genome sequencing data from multiresistant bacteria. I am especially interested in prediction of resistance phenotype based on genotype.
