Liza Konnikova, MD, PhD, FAAP, is a neonatologist at UPMC Children's Hospital of Pittsburgh and an assistant professor in the Departments of Pediatrics, Developmental Biology and Immunology in the University of Pittsburgh School of Medicine. Her lab focuses on the develop of neonatal immunity at mucosal surfaces and its role in the pathogenesis of diverse diseases such as sepsis, preterm labor, necrotizing enterocolitis, and very-early onset IBD (VEO-IBD). She has pioneered the application of mass cytometry to frozen mucosal biopsies, helping to improve our understanding of mucosal immunity. This innovation has helped to identify novel populations of immune cells in VEO-IBD and to perform serial monitoring of IBD activity during drug trials.
