Luis A. Bagatolli obtained his M. Sc. (1991) and Ph. D. degree (1995) from the School of Chemical Sciences, University of Córdoba in Argentina. After a postdoctoral research at Laboratory for Fluorescence Dynamic, University of Illinois at Urbana- Champaign, USA (1997-2000), and a brief stay in Argentina, he joined in 2002 MEMPHYS - Center for Biomembrane Physics at the University of Southern Denmark (SDU) where he worked until February 2017. At present, he is a Researcher (Investigador Principal) of the Argentinian Research Council (CONICET) in a node located in the city of Córdoba (Instituto de Investigación Medica Mercedes y Martín Ferreyra). He is also an associated member at MEMPHYS- international and interdisciplinary research network.


Research Interest


My current research interests are related to physicochemical (biophysical) aspects of biological systems, particularly the effect of non-equilibrium conditions, crowding and spatial confinement in membranous systems and cells. I am also interested in the development and applications of biophotonic-related techniques to biological systems (fluorescence spectroscopy, imaging techniques based in multiphoton excitation microscopy). I have authored numerous papers, review articles and book chapters, including 2 books, on topics such as lipid-lipid and lipid-proteins interactions in membranes (composed of synthetic lipid mixtures, natural membrane’s lipid extracts, naturally occurring biological membranes) and performed studies on skin tissue.
