About

Biography

The focus of his teams basic research has been to identify the molecular mechanisms involved in the embryonic development of endocrine cells including pancreatic beta cells and tissues of the gastrointestinal tract. Their translational projects have focused on identifying new approaches to improve child health in several ways: 1. To identify and use embryonic pathways to generate complex, three-dimensional organ tissues from pluripotent stem cells, 2. Use these tissues to develop new in vitro human models for diabetes and digestive disease research and 3. Develop long-term, therapeutic strategies for cell and tissue-replacement therapies.
