Expertise and research interests

The TumHyp team aims at understanding how cancer cells respond to anti-cancer therapies including radio-, chemo and immunotherapies as well as to targeted nanoparticles. The role of tumor microenvironment, more particularly of endothelial cells, macrophages, inflammation and hypoxia, in tumor growth, response to treatments and metastasis is also investigated.

Together with physicists Prof. Stéphane Lucas and Prof. Anne-Catherine Heuskin (UNamur, NARILIS), Prof. Carine Michiels set up an experienced radiobiology team. This multidisciplinary collaboration connecting biology and physics has the objective to optimize conventional radiation therapy, as well as to achieve a more efficient cancer treatment by combining nanotechnology and protontherapy.
