Ana M. G. Silva received her PhD in Chemistry from UAveiro in 2002 and completed her graduation in Chemistry, Food Chemistry in 1997 at the same University. In 2003, she was awarded with an FCT post-doctoral fellowship (SFRH/BPD/8374/2002) at UAveiro, where she acquired a solid expertise in organic chemistry, particularly in porphyrin’s chemistry. During the PhD and Post-doc periods, she carried out 3 internships with research groups of: Prof A. Dondoni (UFerrara, Italy) and Prof O. Kappe (UGraz, Austria), where she learned advanced strategies to synthesise carbohydrate derivatives and developed various microwave protocols related to the porphyrins derivatization. Since 2007, she holds a researcher position (with different contractual levels) at REQUIMTE, UPorto. While maintaining interest in porphyrin chemistry, she started a new line of research dedicated to the synthesis, characterization and development of strong bright xanthene fluorophores using sustainable chemistry approaches, for applications in medicine and environment remediation. In 2015, she held a temporary position (4 months) as a NMR spectroscopy technician at CEMUP, UPorto, while simultaneously keeping active her scientific research commitments. AMGS merged her know-how in organic chemistry with her expertise in metal complexes to create new multifunctional ligands and luminescent materials for sensing applications and as a result in 2016 she was congratulated as a coordinator of the project M-ERA-NET/0005/2014.
