Dr. Siegal was born in New York where he attended college. He received his medical degree from the University of Louisville and his PhD from the University of Minnesota. He was a Resident and Research Fellow at the Mayo Graduate School of Medicine and completed both a post-doctoral fellowship at the National Cancer Institute, NIH and a surgical pathology fellowship at the University of Minnesota. Prior to coming to UAB in 1990, he was a tenured faculty member at the University of North Carolina at Chapel Hill. Dr. Siegal has been married for over 40 years and has 2 adult daughters and 4 grandchildren.
Dr. Siegal is an extramurally funded experimental and diagnostic pathologist whose research interest for more than 3 decades has been focused in Cancer Biology. Specifically, he has been interested in studying tumor-matrix interactions during angiogenesis, tumor invasion and metastasis in breast cancer. Previous efforts by his group have been directed towards developing new reliable in vitro model systems for studying the effect of nutritional and other factors on prostate and breast cancer progression in humans. He has participated in multiple gene therapy studies utilizing a variety of distinct strategies including mutation compensation, genetic immunopotentiation, and molecular chemotherapy to treat solid human neoplasms, principally ovarian carcinoma. He was most recently funded to develop a conditionally replicating canine adenovirus model that could be used to study host-vector interactions for more effective antitumor oncolytic effect. Dr. Siegal also directs the Histomorphometry & Molecular Analysis Core of the UAB Core Center for Musculoskeletal Disorders. Dr. Siegal's clinical research interests have focused on studies of bone tumors and related conditions. He is the Editor-in-Chief of Laboratory Investigation and serves on the editorial board of an additional twenty journals.
