Joachim Wittbrodt, a renowned biologist, focuses on developmental biology and eye development. His Heidelberg University lab studies cell proliferation and differentiation in fish like zebrafish, aiming to uncover mechanisms governing this balance. They use genetics, imaging, and molecular methods, especially in the retina and brain, revealing insights into retinal growth, stem cells' role, and teleost eye regeneration. The lab also examines key genes' cellular impact on retinal development and regeneration in the population context.
