Deborah L. Chapman is an Associate Professor at the University of Pittsburgh, specializing in developmental biology. Her research focuses on the molecular mechanisms governing mesoderm specification and patterning during embryogenesis, particularly the roles of T-box transcription factors T and Tbx6 in somite formation and birth defects such as rib fusions and scoliosis. Dr. Chapman received her Ph.D. in 1993 from Columbia University under Debra Wolgemuth, followed by postdoctoral work with Virginia Papaioannou at the same institution. She joined her current department in 1998, where she investigates how altered T-box gene expression disrupts embryonic development using mouse models and molecular techniques like luciferase assays and chromatin immunoprecipitation. Research Themes: Mesoderm fate decisions, T-box competition, segmentation clock, Notch/Wnt signaling, human birth defect modeling. Methods: Transgenic mice, gene knockout analysis, enhancer studies, transcriptional profiling. Recent publications highlight her work on Tbx6 dosage effects, evolutionary conservation of T-box functions, and integrative signaling pathways in somitogenesis. Her lab continues to explore gene regulatory networks in embryonic patterning and their clinical implications. Contact: dlc7@pitt.edu
