Explore a lecture on the intersection of mathematical modeling and developmental biology where Eric Siggia discusses the strategic application of quantitative methods to biological problems. Learn how phenomenological approaches from physics can be applied to developmental genetics, offering a middle ground between overly detailed and overly general models. Discover how modern dynamical systems mathematics shares similarities with experimental embryology, allowing for geometric categorization of developmental behaviors. Through examples from stem cell differentiation and model organism embryos, understand how systems with few variables can effectively model cell state transitions. The presentation demonstrates how this phenomenological approach is crucial for bridging scales from cellular to embryonic development by creating separately parameterizable components. This one-hour lecture provides insights into how mathematical frameworks can enhance our understanding of genetic processes without requiring exhaustive gene enumeration.
