Research interests

DK: Ingangværende forskning fokuserer på molekylær og eksperimentel stråleonkologi, specielt på omdannelsen af grundvidenskab til kliniske omgivelser. Dette indebærer beskrivelsen af det biologiske grundlag for strålingsinduceret sygelighed og tumor strålefølsomhed. Denne viden skal bruges til a) forudsigelse og indgriben af sygelighed og b) udvikling af biomarkører til prognoser og forudsigelser af terapeutiske strategier for tumor reaktion. 

UK: Ongoing research focuses on molecular and experimental radiation oncology, particularly on the translation of basic science into clinical settings. This involves characterization of the biological basis for radiation-induced morbidity and tumour radiosensitivity and using this knowledge for a) prediction and intervention for morbidity and b) development of biomarkers for prognosis and prediction of therapeutic strategies for tumour response.
