LIFE AND MATHEMATICAL SCIENCES

Unravel the mysteries of biological morphogenesis with a comprehensive framework that connects experimental observations, hypothesis formulation, simulations, and inference computations. This video showcases how these elements integrate to provide insights into the mechanisms driving tissue folding and 3D shape formation. Key Topics: Experimental observations as a foundation for modeling morphogenesis Hypothesis-driven simulations of tissue deformation Biological relevance to neural tube formation, intestinal villi, and beetle horn development Inference computations revealing the role of spatial patterns in differential growth This approach bridges theory and experiment, advancing our understanding of developmental biology and bioengineering applications.
