Short CV

Teresa Margarida Santos was born in Sarrazola ( Cacia ) on February 22, 1954 . She graduated in Chemistry-Educational Branch, Faculty of Sciences, University of Porto (1977) . After "Scientific and Pedagogical Capacity Skill Profs" in the Chemistry Department of University of Aveiro, in 1987, obtained her PhD in Chemistry ( Inorganic ) in 1995, also at Aveiro University, under Professor Júlio Pedrosa de Jesus supervision, with the thesis "Coordination Chemistry of Cr(III) and Cr(VI) compounds related with the biological effects of Chromium". Before landing in Aveiro she was a High School Teacher across the country, with a brief passage in UTAD University. Since 1983 her professional activities have been developed in the  Chemistry Department of the University of Aveiro, where she is Assistant Professor.
