Current Research & Key Publications

Major societal challenges of the 21st century are Human Health and Wellbeing and the Pressure on Natural Resources. My goal, aligned with the CBMA strategic program and Horizon 2020, is to conduct cutting-edge research through a problem-oriented approach enabling breakthrough innovations, new tools and strategies impacting health promotion and environmental sustainability. I have established an independent research line studying proteasome-mediated modulation of cell death induced by chemotherapeutic agents, and collaborate with senior researchers in the apoptosis field, applied to cancer research. More recently, I started a CBMA effort focused on environmental monitoring and drug discovery.
