At the radiobiology laboratory, the general research interests are in the areas of oncology bioinformatics, multimodality image analysis, and treatment outcome modeling. The primary motivation is to design and develop novel approaches to unravel the response of cancer patients to chemo-radiotherapy treatment by integrating physical, biological, and imaging information into advanced mathematical models. These models could be used to personalize the chemo-radiotherapy treatment of cancer patients based on predicted benefit/risk. We also investigate the use of bone marrow derived stem cells in the reduction of radiation pneumonitis, one of the most common side effects observed in lung cancer patients after irradiation. For this, we developed an animal (rat) model of radiation pneumonitis, and tested different administration routes of Mesenchymal stem cells derived from bone marrow. We are also interested in investigation alternative therapies that potentially will reduce radiotherapy side effects.
