As a Director of two Year 2 courses -- Pathology 201, which focuses mainly on the general mechanisms of diseases, and Pathology 202, which focuses mainly on specific organ diseases -- Dr. Diaz is responsible for the quality of the teaching of these two courses, including lectures, small group discussions and the clinicopathological correlation sessions. Dr Diaz is a Tenured Professor in the Department of Biomedical Sciences and a member of the Years 1 and 2 Curriculum Committee.
Dr Diaz joined the faculty of the University of South Florida (USF) within the Department of Pathology at the H. Lee Moffitt Cancer Center and Research Institute in Tampa (Florida) in 1991, where he served as an expert genitourinary and gastrointestinal pathologist and as a Chief of Surgical Pathology. In 2001 he joined the Florida Hospital Department of Pathology in Orlando (Florida) as a Director of Molecular Pathology. In 2002 he returned to Eastern Virginia Medical School (EVMS) in Norfolk (Virginia), where he initially trained in Pathology, as Professor and Vice Chairman of Pathology, as Director of the Anatomic and Molecular Pathology Laboratories and as a Director of Genitourinary Pathology Services and a member of the Virginia Prostate Center and the George Wright Center for Biomedical Proteomics, an internationally recognized laboratory for its contributions on serum protein profiling with mass spectrometry for the early detection of prostate cancer. In 2006 he joined the faculty of the Cancer Therapy Research Center’s (CTRC) Institute for Drug Development (IDD) at the University of Texas in San Antonio (Texas), where he served as a Chairman of the Division of Molecular Pathology and Director of the Molecular Oncology Targeted Therapy Program. In the summer of 2008 Dr. Diaz joined the faculty of the Florida State University College of Medicine (FSUCOM) to continue his career with a new focus on medical education in Pathology. While still serving as full-time faculty at FSUCOM, in the summer of 2010 Dr Diaz became the Medical Director for the Pathology Laboratory at the Tallahassee Endoscopy Center-Digestive Disease Clinic. Dr. Diaz is an accomplished genitourinary pathologist and has published extensively on this field. He is a diplomate of the American Board of Pathology in both Anatomic and Clinical Pathology. He is also one of the first and few US pathologists certified on “Molecular Genetic Pathology” by the American Boards of Pathology and Medical Genetics. He is married to Inmaculada Silverio and has two children: Igancio Diaz-Silverio and Sergio Diaz-Silverio.
Dr Diaz obtained his MD and PhD from the Autonoma University of Madrid College of Medicine (Spain) in 1982 and 2000, respectively. In 1983 he moved to the U.S.A. as a fellow in Reproductive Endocrinology at the Jones Institute for Reproductive Medicine in Norfolk (Virginia). The first sucessful "Human In Vitro Fertilization" attempt in America was achived at this institution in 1983. This was the third sucessful attempt in the world after the first two in England and Australia, respectively. In 1986 he began a new career in Cancer Research completing his training in Anatomic Pathology at EVMS and subsequently, a fellowship in Surgical Pathology and a Residency in Clinical Pathology at the Cleveland Clinic Foundation in Cleveland (Ohio). In 1993 while being faculty at USF, he took a sabbatical to train in Molecular Genetic Pathology at the New England Medical Center (Tufts University) in Boston (Massachusetts).
Dr. Diaz has been co-investigator on multiple NIH/NCI and DOD sponsored grants and has presented numerous didactic and research seminars nationally and internationally. He is member of the Editorial Board of Frontiers in Bioscience and Reviewer for the Journal of Urology. He has served in many Hospital, University and National Committees, including: 1) South Western Oncology Group Genitourinary Committee, Translational Medicine Subcommittee, 2) Inspector for the College of American Pathologist’s Laboratory Accreditation Program in Anatomic, Clinical and Molecular Pathology, 3 Pediatric Oncology Group, 4) South Western Oncology Group: Hematopathology Subcommittee. Dr Diaz is currently a member of the Group of Research in Pathology Education (GRIPE), a national organization of educators in the field of Pathology represented by most medical medical schools in the USA. He serves as a member and was the previous Chair of the “Team Based Learning” Committee until the summer of 2012.
