Prostaglandin-nuclear receptor-angiogenic signaling axis during embryo implantation with special emphasis to cPLA2α-Cox2-PPARδ-Vegf network in the uterus; cytokine-growth factor-homeobox-morphogen signaling axis in implantation involving Lif-Hb-Egf-Hoxa10/Msx1-Ihh/Bmp/Wnt network in the uterus; immunophilin/cochaperone-nuclear signaling in the mouse uterus during implantation involving Fkbp52-PR; ligand-receptor signaling with endocannabinoids during the periimplantation events in mice in the context of anandamide interacting with G-protein coupled receptors, CB1 and CB2; molecular and genetic basis of epithelial ovarian cancer with special reference to prostaglandin-PPAR signaling; miRNA and Cox-2 regulation in uterine biology and cancer; Pten and uterine carcinoma: conditionally gene deleted mouse models

Dr. Dey received his PhD from The University of Calcutta College of Sciences in 1972, after which he received postdoctoral training at the University of Kansas Medical Center from 1973-1977, followed by his faculty appointment in 1977 where he rose to the rank of University Distinguished Professor. He moved to Vanderbilt University as Dorothy Overall Wells professor of pediatrics, cell and developmental biology and pharmacology in 2002. In both places he directed NIH-funded reproductive biology training grants. In 2008, Dr. Dey moved to Cincinnati Children’s Hospital Medical Center as Lova Riekert Chair and professor of pediatrics to start a new Division of Reproductive Sciences. He has published over 300 original articles and has been funded by two MERIT Awards, RO1 grants and a Program Project Grants from NIH, and grants from the Bill and Melinda Gates Foundation and March of Dimes Foundation. His research mission has been to define the molecular road map to embryo-uterine interactions during pregnancy. His recent work published in Developmental Cell, Nat Med, PNAS and JCI provides novel information in the context of cell polarity in implantation, ectopic pregnancy, progesterone resistance to pregnancy failure and premature decidual senescence in preterm delivery. In 2008, Dr. Dey received Carl G. Hartman Award, the highest honor of the Society for the Study of Reproduction. In 2009, he received IVI Award sponsored by Schering-Plough for best contribution in Reproductive Medicine.

He has graduated seven PhD students and mentored over 40 postdoctoral fellows, 20 of whom are currently independent faculty members, and most others are investigators in major research institutions. His laboratory currently consists of one junior faculty, four postdoctoral fellows, one MD/PhD student, and two research assistants.
