The main focus of the research

  • Neonatal infections: virulence markers of causative agents, optimization of neonatal sepsis treatment and prevention regimens; pharmacokinetics, pharmacodynamics and modeling of antibiotic therapy, clinical trials
  • HIV infection in Estonia: prevalence in populations, viral resistance markers, the relationship between the virus and the host, co-infections, human and viral genetic factors influencing HIV infection
  • Human microbiome from birth to death and its link to health: microbial communities in the gastrointestinal and reproductive tract, mouth and skin; their disorders in various infectious and non-infectious diseases
  • Biotechnological solutions for health: development of novel probiotics and synbiotics in laboratory and clinical trials
  • Antibiotic resistance: prevalence of resistance, factors influencing the development of resistance, prevention of the development of resistance, rational use of antibiotics
  • Monitoring of vaccine-preventable diseases: epidemiological changes over time, modeling
