Karen Brajão de Oliveira graduated in Biomedicine from the State University of Londrina (2000–2004), and holds a Master's degree (2006) and a Ph.D. in Experimental Pathology from the State University of Londrina (2010). Currently, she is an Associate Professor-B in the area of Immunology and a Researcher at the State University of Londrina, where she also serves as a Professor and Advisor in the Experimental Pathology Program. Additionally, she is a member of the Ethics Committee in Human Research at UEL. Dr. Oliveira coordinates the Laboratory of Molecular Genetics and Immunology and the Polymorphism Research Laboratory. She has published over 50 papers in prestigious international journals and her research focuses on understanding the influence of genetic polymorphisms in immune molecules on HPV infection, the susceptibility to and development of cervical cancer, as well as the influence of these genetic variants on the progression of head and neck squamous cell carcinoma and breast cancer. Her work aims to uncover the molecular mechanisms that contribute to these diseases.
