My research focuses on the biophysical chemical understanding of phenomena occurring at biological membranes. In particular, I continue to explore questions such as 1) the structure of biomembranes dependency on composition and interactions with biomolecules and other relevant compounds, 2) the formation of membrane bound protein complexes at biomembranes and how are these regulated by the membrane composition, 3) the role of biomembrane composition and structure on lipid exchange processes between lipid based nanoparticles including lipoproteins (the body carriers of fat) and 4) lipid based nanoparticle structure and the effect of protein corona. In this talk, I will cover some of the work my research group has done mainly on the study and development of antimicrobial compounds as well as the mapping of the structural and compositional reasons for the function of the good and bad cholesterol in our bodies. In order to answer these questions we undertake a cross-disciplinary approach that combines traditional surface and colloidal chemistry, biochemistry, molecular biology and biophysics. One of the main techniques used in my research is neutron scattering. The work is highly cross-disciplinary and I count with strong and fruitful collaborations with colleagues within the Life Sciences.
