Research Activities:
Dr. Torday was born in Budapest, Hungary. He has been a member of the faculties of Harvard Medical School, Departments of Pediatrics and Physiology; The University of Maryland School of Medicine, Departments of Pediatrics and Obstetrics and Gynecology; and The David Geffen School of Medicine, Departments of Pediatrics and Obstetrics and Gynecology (1998–present).

He is currently a Professor of Pediatrics and Obstetrics and Gynecology. As a member of the Division of Neonatology, he is the Director of the Perinatal Biology Training Program, and the Director of the Henry L. Guenther Laboratory for Cell Molecular Biology at Harbor-UCLA Medical Center. He has trained more than 100 research fellows and graduate students in research methods and concepts during the course of his career in Neonatology, Obstetrics and Gynecology, and Physiology.

Dr. Torday is a pioneer in the field of developmental lung biology, with current research interests in the developmental/phylogenetic origins of lung cell phenotypic heterogeneity and the gene regulatory network determinants of lung evolution. He is particularly interested in using evolutionary biology of the lung as an approach to clinical diagnosis and treatment of chronic lung disease, and as a prototype for predictive and preventive medicine.

He has authored 150 peer-reviewed journal articles, and 321 abstracts, the majority of which form the basis for the conceptualization of evolutionary mechanisms in medicine, including a series of 12 journal articles that specifically address this subject in opinion pieces. The journal articles on evolution and medicine form the basis for a monograph entitled "Evolutionary Biology, Cell-Cell Communication and Complex Disease" (JS Torday and VK Rehan, Wiley-Blackwell, January 24, 2012). The book is a ‘primer’ for mechanistic thinking in evolution and medicine. It is intended for both established investigators and those in training.
