Education

• Graduation on Physical-Chemistry Sciences , Faculty of Sciences, University of Lisbon (1967)
• PhD. on Chemistry, Instituto Superior Técnico (A. R. Dias, 1984, Thermochemistry of biscyclopentadienyl compounds of Titanium)

Scientific interests

     As Membro integrado of Centro de Química Estrutural, the scientific interests of M.Margarida Salema in the field of Inorganic and Organometallic Chemistry, led her to be involved in thermochemistry of titanium compounds and more recently in synthesis, characterization and reactivity studies of biscyclopentadienyl organometallic complexes of Mo, W or Ti with heterocycles or biphenyl substituted ligands.

Academic Duties

• Coordination of the first year graduation studies at the Chemical and Biological Engineering Departement
• At Instituto Superior Técnico she has been assistant professor in several  areas of Inorganic Chemistry and Organic Chemistry and, mainly, Chemical Bonding, for the graduations in Chemical Engineering, Biological Engineering and Chemistry.
