About Dr. Leomar Y Ballester
My education consists of a B.S. in Biological Sciences at the University of Puerto Rico-Mayaguez, an M.D. degree at the UPR School of Medicine and a Ph.D. in Biomedical Sciences from the Department of Pharmacology at Vanderbilt University. Subsequently I joined the National Cancer Institute for Residency training in Anatomic Pathology (where I also served as chief resident). This was followed by fellowships in Molecular Genetic Pathology at Baylor College of Medicine and Neuropathology at the Houston Methodist/MD Anderson program. I am board certified by the American Board of Pathology in Anatomic Pathology, Neuropathology, and Molecular Genetic Pathology. I joined the Departments of Pathology and Translational Molecular Pathology at MD Anderson with goal of focusing on CNS tumors. As a neuropathologist, I am interested in the biology, diagnosis and treatment of brain cancer. As a molecular pathologist, I am interested in developing and implementing clinical molecular diagnostic assays. My research interests involve the combination of histology and genomics to study the pathogenesis of brain tumors, identify clinically useful biomarkers and translate cancer genomic discoveries into clinical diagnostic assays. In addition to my clinical responsibilities in neuropathology and molecular genetic pathology, I am the principal investigator of a research laboratory focusing on brain tumor biomarkers and I was recently awarded a K08 grant from NCI to study CSF biomarkers in patient with CNS malignancies.
