The Fontana lab designs computational models to reason biological knowledge. Interests span the development and application of rule-based formalisms for modeling complex systems of molecular interaction, causality in concurrent systems, the interplay between network growth and network dynamics, phenotypic plasticity and evolvability, learning, and aging. The lab's approach is computational and theoretical. In the past, the lab also conducted experimental work using C. elegans as a model system. The members and collaborators of the lab typically come from diverse backgrounds, such as molecular biology and genetics, mathematics, computational biology, physics, chemistry, engineering, and computer science.
