Collaborations outside COST

My lab collaborates with pharmaceutical companies to assist in the development of new therapeutics (pre-clinical to phase 2 clinical trials). This work is carried out through Java Clinical Research, for which I also act as a scientific consultant. I have also established a vascular biobank in collaboration with The Mater Hospital, Dublin (atherosclerotic plaques). I also develop diagnostic and prognostic indices tests to monitor cardiovascular competence in exercise rehabilitation clinics (MedEx) for chronic illnesses (Cardiovascular disease, cancer, peripheral artery disease, COPD, diabetes). I also work with the European and French Space Agencies (ESA and CNES), in collaboration with Prof. Marc-Antoine Custaud (University of Angers, France) on the physiological effects of space flight (microgravity) on the cardiovascular system, focusing on platelet physiology. We also have developed a high through put miRNA functional target screen, in collaboration with Prof. Marco Mangone (Arizona State University).

Short description of ongoing research projects

Platelets as a biomarker of epigenetic drift in the cardiovascular compartment (mitochondrial epigenetics, platelet function and physiology, platelet miRNA biology); Epigenetics and miRNA biology of vascular cells (endothelial and vascular smooth muscle cells) and the role of biomecanotransduction in their regulation. Integrin signaling and cytoskeleal dynamics. Microvesicle biology (role in health and disease). Circulating stem cells. Targeting vascular inflammation (role of miRNA and epigenetics).
