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 education.

She leads the Microbiology and Applied Phycology Labs of the University of Malta. For the past fifteen years, she has lectured and supervised students enrolled in various undergraduate and postgraduate degrees both in Malta and abroad.

Her research interests include the molecular genetic characterisation of microbial biofilm communities and their biochemical processes. She has isolated in culture a large number of bacteria and microalgae which grow in different habitats in Malta. Most are new strains that have not yet been described taxonomically. Her current research deals with their phylogenetics and systematics and the extraction of new bioactive substances for prospective application in biomedicine and industry.
