Berna Sozen

Group Leader

Dr. Berna Sozen, is an Assistant Professor of Developmental Stem Cell Biology at Yale University, Department of Genetics and Bohmfalk Scholar at Yale School of Medicine.

Dr. Sozen trained as a Developmental Biologist at Akdeniz University, Turkey and later at the University of Cambridge, UK. She then undertook her post-doctoral research first at Cambridge, and later at California Insitute of Technology (Caltech) during which she developed in vitro systems to model mammalian early embryogenesis using various types of stem cells, in Magdalena Zernicka-Goetz group. In 2020, she established her independent research group at Yale Department of Genetics.       

Dominica cao

research ASSISTANT

Dominica graduated from Smith College with BAs in Neuroscience and Biology, working as a teaching assistant during her years in the Valley. She spent a summer in the O’Roak lab at OHSU to study cortical lamination in patient-specific mouse models of autism, and joined the Barresi lab at Smith to model neurodevelopmental diseases in transgenic zebrafish. With a growing interest in development at its earliest stages, Dominica joined the Sozen lab in January 2021 as a Research Assistant, working with mammalian embryos and their stem cell models to study developmental responses to perturbation.

Jenna bergmann


Jenna is a Yale MD-PhD student and aspiring developmental biologist with a clinical interest in obstetrics and gynecology. Jenna graduated from Barnard College in 2018 where she majored in Cell & Molecular Biology and Latin. At Barnard, she conducted her thesis research in the Mansfield lab studying tissue-specific effects of the Hoxa5 transcription factor on musculoskeletal development. After graduating from Barnard, she spent one year as a research technician for the Houvras lab at Weill Cornell before matriculating in the Yale MD/PhD program. Jenna will begin her PhD research in the Sozen lab in Fall 2021.
