General Information

How do seemingly random mixtures of molecular components and swimming microorganisms organize themselves into large-scale cellular structures and synchronize to execute collective motions? What is common to these processes? Can we model them mathematically and simulate them computationally? What can we learn about the biofluids flows and self-organization of biological systems by developing and analyzing mathematical models?

The workshop will bring together mathematicians, statisticians, biophysicists and engineers to discuss the latest developments in the field of self-organization and multi-scale description of active biological systems, such as suspensions of swimming microorganisms and biofluids, evolving cytoskeletal networks, and many others.

The workshop will address the following mathematical and statistical issues:

Homogenization and upscaling in active systems (suspensions of swimmers, cytoskeletal networks, biological tissue)
Analysis of mathematical model of self-organization in biological systems
Novel computational algorithms for simulations of biological processes

Complementary research thrusts include the statistical properties of self-organized collective states and macroscopic effects of intrinsic stochasticity in active systems, such as velocity and density fluctuations, phase transitions, critical behavior, rheology and constitutive relations.

Organizers: Igor Aronson (Argonne National Laboratory), Leonid Berlyand (Penn State University); Directorate Liaison: Pierre Gremaud

Researchers who have agreed to speak include: Anna Balazs (University of Pittsburgh), Andrea Bertozzi (UCLA), John Brady (Caltech), Suncica Canic (University of Houston), Thierry Collin (University of Bourdeaux), Margaret Gardel (University of Chicago), Jerry Golub (Haverford College), Yulia Gorb (Texas A&M), Michael Graham (University of Wisconsin-Madison), Danielle Hilhorst (Universite Paris-Sud), James Keener (University of Utah), Simona Mancini (Universite d'Orleans), Tim Pedley (University of Cambridge), Benoit Perthame (Universite Pierre et Marie Curie), Jacques Prost (ESPCI), and Michael Shelley (Courant Institute).
