Dr. Alejandro Corvalán is Medical Doctor and Master in Sciences from University of Chile in 1985 and 2006. Clinical and research training in Molecular Pathology at Mount Sinai School of Medicine in New York and Tokyo Medical and Dental School of Medicine in 1992 and 2001. Currently Associate Professor at Pontificia Universidad Católica de Chile and Principal Investigator of the Advanced Center for Chronic Diseases (ACCDiS). Academic activities include translational research as well as postgraduate education in Oncology. His research focus in clinical and molecular associations of gastric cancer. Through this approach he discovers a high association of the Epstein-Barr Virus (EBV) as well as the presence of unique strain of EBV in gastric cancer. In addition, he has strong interest in hereditary tumors as well as the role of epigenetics in precursor lesions of gastric cancer. These discoveries not only contribute to the understanding of the pathogenesis of these neoplasms but also act as potential biomarkers for non-invasive diagnosis, monitoring treatment response and developing new treatments.
