lessTitle: Advances in Asymptotic and Computational Methods for Biological Transport
Speaker: Dr. Alan Lindsay, University of Notre Dame
Abstract: Asymptotic analysis remains one of the most powerful analytical tools for extracting interpretable information from mathematical models in science. These methods systematically exploit multiscale structure to reduce complex and often intractable problems to a sequence of tractable sub-problems. When coupled with modern numerical methods, they greatly expand the range and scope of scientific questions that can be addressed.
In this talk I will discuss the insights these tools have yielded into the role that geometry, dynamics and localization play in biological transport. For the diffusive delivery of cargoes to small reactive sites, they give precise information on how the spatial organization of those sites shapes function. This has led to new solutions to the long-standing Berg-Purcell problem and the narrow escape problem. Underpinning these results is a suite of high-order boundary integral solvers which pair with asymptotic methods to resolve multiscale features and massively expand the geometric scope of biological problems that can be investigated. Throughout the talk I will highlight where interactions with experimental science have guided the direction of the mathematics, and I will close with promising directions for future enquiry.
Bio: Alan Lindsay is an Associate Professor of Applied and Computational Mathematics at the University of Notre Dame. His research group combines mathematical modeling and analysis with computational tools to uncover the rules governing decision making in cellular systems. Prof Lindsay received his B.Sc. in Mathematics at the University of Edinburgh, Scotland and Ph.D. in Applied Mathematics from the University of British Columbia, Canada.Zoom: https://northwestern.zoom.us/j/98486002568

lessTitle: The Hidden Architecture of Disease: How Animal Behavior Shapes Infectious Disease Transmission
Speaker: Dr. Shweta Bansal, Georgetown University
Abstract: Host social behavior represents a major gap in our understanding of infectious disease dynamics, from emergence to forecasting to elimination. In this talk, I'll use a comparative analysis across 90+ animal species to show the opportunities and constraints social networks provide for infectious disease transmission. I'll conclude with a case study of bottlenose dolphins, demonstrating how integrating social and spatial network data can predict individual disease vulnerability and optimize wildlife surveillance strategies.
Bio: Shweta Bansal is a Professor at the Department of Biology at Georgetown University. She also serves as graduate faculty in the Global Infectious Diseases PhD Program and the Biology PhD Program and is an Affiliate Faculty for the Massive Data Institute, the Global Health Institute, and Earth Commons. With a passion for interdisciplinary approaches, she has made significant contributions to mathematical epidemiology, disease ecology, network science, and public health.
Dr. Bansal earned her Bachelor of Science degree in Mathematics and Computer Science at Santa Clara University. She then pursued her graduate education at the University of Texas at Austin, where she earned an M.S. in Computational & Applied Mathematics and a Ph.D. in mathematical epidemiology with a focus on network modeling. Her doctoral research focused on developing innovative mathematical models and algorithms to better understand the spread and design effective control strategies for infectious diseases within populations. After completing her doctorate, Dr. Bansal became a fellow of the prestigious RAPIDD Postdoctoral Program and developed novel methods for understanding the spread of foreign animal diseases of national security concern. During this time, she also advised the Subcommittee on Foreign Animal Disease Threats of the National Science and Technology Council.
Beyond her research endeavors, Dr. Bansal is deeply committed to teaching and mentorship. She has supervised numerous graduate and undergraduate students, guiding them in their research and to pursue careers in computational epidemiology and public health.
Since 2024, Dr. Bansal has served as the Chair of the Founding Committee of the Global Society for Infectious Disease Dynamics (GSIDD), a new global professional society to serve the community of researchers, practitioners, and educators in infectious disease dynamics. Additionally, she is involved in various community outreach initiatives to raise awareness of the importance of an inclusive, diverse, and just future for the next generation of scientists.Zoom: https://northwestern.zoom.us/j/94342367823

lessTitle: Symmetry Breaking, Directed Movement, and Organized Tissue Response from Local Interactions
Speaker: Dr. Calina Copos, Northeastern University
Abstract: Pattern formation and symmetry breaking have long been areas of interest in applied mathematics. In living systems, these questions take on additional complexities: molecular interactions generate dynamic intracellular structures, individual cells develop persistent migratory behaviors, and populations of cells coordinate their dynamics to produce spatiotemporal patterns. A central question is how do biological systems break symmetry, select among competing dynamical states, and coordinate response across scales?
Using cell doublets as the smallest nontrivial collective unit, I will discuss mathematical models, computational methods, and dynamical systems approaches for investigating how local feedback, geometry, and confinement shape these collective dynamical states. We examine how mechanochemical interactions generate directional and coordinated migration, biases, and how nonlinear feedback and spatial coupling give rise to coherent oscillations, traveling waves, and other patterns. Extending these principles to larger cell clusters and tissues reveals emergent organization with implications for development, wound healing, and limb regeneration. These examples illustrate how mathematical models can bridge scales and uncover principles by which local interactions generate global organization.
Bio: Calina Copos is an Assistant Professor of Mathematics and Biology at Northeastern University. Her research group is broadly interested in mathematical biology and numerical and computational methods for PDEs, with a particular focus on the cell cytoskeleton and cell migration in tissue development, homeostasis, and regeneration. Prof. Copos received her Ph.D. in Applied Mathematics at University of California, Davis and did her postdoctoral work at the Courant Institute at New York University.
