Dr. Lidia Feliu obtained a BSc degree in Pharmacy from the University of Barcelona (Spain), where she started her scientific career and completed her PhD degree in 2000. During this period, her research was focused on the total synthesis in solution of marine pyridoacridine alkaloids with antitumor activity. After the PhD, she participated in a project centered on the preparation of azetidines which involved the University of Barcelona and the pharmaceutical company Vita Invest. In 2001, Dr. Feliu obtained a two-year postdoctoral position at the University of Montpellier (France) as Marie Curie Fellow. The postdoctoral research allowed her to start working on solid-phase synthesis and combinatorial chemistry as well as on peptides incorporating a spiroimidazolidinone motif. In 2003, Dr. Feliu moved to the University of Girona (Spain) where she obtained a Marie Curie Reintegration Grant. She joined the LIPPSO group from the Department of Chemistry as lecturer and she became Associate Professor in 2008.The main research topics in which she is now involved are: the design and the synthesis of linear and cyclic peptides, depsipeptides, cyclolipopeptides and multivalent peptides, with antimicrobial and antitumor activity, as well as the development of solid-phase strategies for the synthesis of peptides containing non natural amino acids.
