- enzymology
- post-translation modifications of hemoproteins
- protein stability and structure-function relationship
- oxidative stress in cells
- heavy metal ions including their complexes (such as free heme) and their effect on cells
- ionizing radiation and its effect on cells
- Identification of new hemoproteins and description of their properties
- Various hemoproteins production and/or isolation, their characterization including protein engineering
- Development of new antibacterial strategies based on the research focused on heme enzymes and heme sensors
- Development of new anticancer strategies based on the research focused on heme-containing sensor proteins that are unique for pathological bacteria
