Giuseppe Lazzara is full professor at the Department of Physics and Chemistry, University of Palermo, Italy. After his Ph.D. at the University of Palermo during which he was one year at Bayreuth University (Germany). He was post-doc at the Lund University (Sweden) carrying out research on supramolecular systems. He was the principal investigator of a project for young scientist (below 40 years old) entitled "Clay nanotubes for designing eco-compatible smart materials" founded by the Italian Minister of Research and University (FIRB 2012). ). His research is devoted to physical chemistry of nanostructured systems fuctional for the environment and cultural heritage. In particular the following main topics can be identified: 1) bionanocomposites based on nanoclays as alternatives to conventional plastics, 2) selective functionalization of nanoclay for smart applications, 3) nanomaterials for conservation of cultural heritage. He contributed over 150 Science Citation Indexed journal articles, 1 co-edited book published by Elsevier Inc. and he is associate editor for Applied Clay Science journal. He has two patents on nanoclay based materials.
