Jean Carlson is a Professor in the Department of Physics at the University of California Santa Barbara, where she heads the Complex Systems Group. Her research spans multiple disciplines including physics, neuroscience, immunology, and earth sciences, with a focus on developing theoretical frameworks for understanding complex systems. She is an active researcher with numerous publications across diverse fields and serves as a mentor to graduate students and postdoctoral researchers. Professor Carlson's research interests center around complex systems theory, with specific applications in theoretical immunology, earthquake physics, neuroscience, granular materials, amorphous solids, and Highly Optimized Tolerance (HOT). Her work on HOT explores the robust yet fragile nature of complex systems across diverse contexts from immune systems to forest fires. She has made significant contributions to understanding friction modeling through constitutive laws, particularly applying Shear Transformation Zone Theory to earthquake physics and granular materials. Her interdisciplinary approach connects physics principles to biological and environmental systems, revealing fundamental patterns in complex phenomena. Analysis of her recent publications reveals a strong trend toward interdisciplinary research that bridges physics with biological and environmental systems. Her work demonstrates consistent application of complex systems theory across diverse domains, from neural networks to earthquake dynamics to immune system function. The research shows increasing integration of computational modeling with empirical data, particularly in neuroscience applications where brain connectivity and learning dynamics are examined through network analysis. Her earthquake physics work consistently applies physical models of friction and strain localization to understand seismic phenomena, while her immunology research applies theoretical frameworks to understand immune system vulnerabilities and tradeoffs. Professor Carlson actively mentors students and postdocs across multiple disciplines, with notable collaborations including Dani Bassett in neuroscience and Nada Petrovic in disaster response modeling. Her research group has secured funding for projects spanning theoretical immunology, earthquake physics, and wildfire management. She has been involved in significant collaborative efforts such as the Network Architectures of Brain Structures and Functions program and the Physics of Climate Change Program at the Kavli Institute for Theoretical Physics at UCSB. Professor Carlson leads the Complex Systems Group at UCSB, which brings together researchers from physics, biology, and environmental science to study robustness, tradeoffs, and feedback in complex, highly connected systems. The group develops multi-scale models to capture important small-scale details and predict large-scale behavior across diverse applications including disaster response, neuroscience, theoretical immunology, earthquake physics, and granular materials. The group has been particularly active in studying Highly Optimized Tolerance (HOT) as a framework for understanding complexity across different domains.
