About

Jorge Pedrosa, born in 1964, holds a degree in Biochemistry and a PhD in Biomedical Sciences.

Jorge Pedrosa is a Full Professor at the School of Health Sciences (ECS), University of Minho (U. Minho), the Director of the Life and Health Sciences Research Institute (ICVS), the ECS Vice-Dean for research, the Director of the ICVS/3B’s-Associate Laboratory and a member of the General Council of U. Minho.

Before his mandate as Director of ICVS, he was de Coordinator of the Microbiology and Infection Research Domain at the ICVS.

In the medical course of the ECS, Jorge Pedrosa is the Coordinator of the Curricular Area “Biopathology and Introduction to Therapeutics”, which associates the themes of Pathology, Genetics, Immunology, Microbiology and Pharmacology.



J. Pedrosa's Research Interests are in the field of Health Sciences-Immunology. He is a member of the Microbiology and Infection Research Domain and he is particularly interested in the host immune response against infections by highly virulent mycobacteria, namely Mycobacterium ulcerans, the causative agent of the emergent tropical disease Buruli ulcer, and Mycobacterium tuberculosis, the causative agent of tuberculosis. He is using animal models in Biosafety Level 3 laboratories and collaborating with a network of health care institutions in Portugal and in Africa, to both evaluate new strategies aiming at the modulation of the host immune response (e.g. design of new vaccines) and to develop new systems of specific delivery of antimicrobial agents to infected cells.

Jorge Pedrosa has published more than 50 peer-reviewed research articles that have been cited more than 1000 times. He has supervised several PhD-Students, and currently supervises or co-supervises 4 PhD-students and 2 Post-Docs.


His main Research Contributions include:

·        First demonstration of a protective role played by neutrophils in the early phase of experimental tuberculosis.

 

·        First isolation from the environment of a pure culture of M. ulcerans, the causative agent of the emergent infectious disease Buruli ulcer, implicating the involvement of aquatic insects in the transmission of this neglected disease.

 

·        Characterization of the host inflammatory response to M. ulcerans;

 

·      First description of an intracellular growth phase for M. ulcerans, as well as of the mechanisms of macrophage-mediated immune control for this pathogen.

 


He has received awards and honours for his research accomplishments, including:

 

- “Pulido Valente Ciência” Award,2010, Fundação Pulido Valente and Fundação para a Ciência e a Tecnologia (FCT)

- Best Paper Award, 2010, Portuguese Society for Immunology (SPI)

- Award “Excelência em Imunologia M. Arala-Chaves”, 2006, Portuguese Society forImmunology (SPI)

- Pfizer Award of Research, 1994, Lisboa

- Boa Esperança Science Award, 1989, JNICT, Lisboa

 

J. Pedrosa has been responsible for several projects funded by national and international agencies and different companies. This includes more than in11 projects with external funding: in 5 as Coordinator; in 6 as responsible for teams with specific tasks.
