Keywords: Malaria drug resistance transporters Plasmodium falciparum


Maria Isabel Veiga, PhD. holds a degree in Biotechnological Engineering. In 2011 concluded her PhD in Medical Sciences at Karolinska Institute, contributing to the knowledge of the importance of transporter genes in the mechanism of drug resistance in the deadliest malaria parasite, Plasmodium falciparum. In 2012 she went to Columbia University, as postdoctoral fellow, to perform transfection-basedmethods to validate if hypothetical single nucleotide polymorphisms found arereliable molecular markers, important for early and accurate detection of resistance.

At present she at ICVS, University of Minho, exploring the developmentof drug resistance in the malaria parasite, concentrating primarily on transporter mechanisms that pump the drugs out of the cell.

Overall, published 22 papers evidencing a unique and translational approach tackling howthe malaria parasite escapes the action of a therapeutic drug. Her work also contributes to reinforce the concept of malaria drug resistance as amulti-factorial and complex phenomenon that not only relates to the parasite’s handling of the incoming drug, but also concomitant responses of its basic physiology and the human host factors.

In recognition of her work, she was awarded this year by L'Oréal/UNESCO Portugal with an Honor Medals for Women in Science and in 2014 awarded by the ESCMID/FEMS with excellent rated project.

International impact of her research can be accessed by the over 650 citations with 77 co-authors rendered into a strong collaborative network translated into funds and students overseas to proceed with post-graduation at the ICVS, UMinho.
