About

Cecilia Leão is a full Professor at the School of Health Sciences (ECS),University of Minho (UMinho). Presently, she is the ECS President and the Presidentof the Ethics Subcommittee for Life and Health Sciences of the UMinho.

Most of her research work has been devoted to the understanding of themechanisms involved in transmembrane transport of weak-organic acids in yeastand their involvement in stress. More recently, she is involved in researchfocusing on the elucidation of the molecular and cellular responses of yeaststo nutritional depletion and its involvement in cell death and aging. She haspublished more than 100 publications peer-reviewed research articles and book chaptersthat have been cited about 2000 times. Throughout the years she has been responsiblefor several research projects, funded by national and international agencies. Inthe scope of the research activity she has been responsible for the supervisionof more than 20 Master and 30 PhD theses.

Cecília Leão has been involved in the organization and scientificcommittee of several national and international meetings. She has alsointegrated several advisory boards, including the International Commission forYeasts, the Editorial Board of the international journals “Microbiology” and“FEMS Yeast Research”, the Scientific and Direction Committee of NationalMicrobiology Society and the Direction Committee of the National BiochemistrySociety. She has received several awards and honours for her researchaccomplishments, from which the most recent are: Member of the Academy forScience of Lisbon (Academia de Ciênciasde Lisboa) and Award Professor Nicolau van Uden 2013, Portuguese Societyfor Microbiology.
