Gabrielle Zammit read for a B.Sc. and M.Sc. (with distinction) at the University of Malta and subsequently completed a Ph.D. in microbial Evolutionary Biology and Ecology. Her doctoral research was conducted at different European institutions including the University of Rome, the University of South Bohemia, the UK's Natural History Museum and the Spanish National Research Council. Gabrielle was awarded the prestigious title 'Doctor Europaea' (European Label) by the European University Association since her research satisfied stringent European doctoral standards established to ensure excellence in research and education. Her postdoctoral research ensued at the University of Malta's Faculty of Medicine and Surgery and at the Centre for Molecular Medicine and Biobanking.

For the past fifteen years, Gabrielle has lectured and supervised students enrolled in various undergraduate and postgraduate degrees both in Malta and abroad. She is presently Resident Academic at the University of Malta's Faculty of Science, where she leads the Microbiology and Applied Phycology Labs.

Her research interests include microbiology and phycology. She has published important papers about the molecular genetic characterisation of Maltese microorganisms and the description of new microbial genera and species. She has isolated in culture a large number of bacteria and microalgae which grow in different habitats in Malta, most of which are new to science. Her current research deals with their phylogenetics, systematics and the extraction of new bioactive substances for prospective industrial application.
