Speaker:
Daniel Abrams, Professor of Engineering Sciences and Applied Mathematics and (by courtesy) Physics and Astronomy, Northwestern University
Title:
Tractable mathematical modeling of social systems: some successes and failures
Abstract:
This talk will be an overview of various problems my group has worked on and approaches we've taken to mathematical modeling of social systems, including approaches that were unsuccessful. We define a system as "social" if dynamics for the individual are inextricably tied to the dynamics of the group. Some problems in this category include evolutionary dynamics (e.g., animal ornamentation, the evolution of human left-handedness), social group competition (e.g., language death, the growth of religiously unaffiliated populations), and the geographic spread of ideas (e.g., internet adoption, contagion of smoking behavior or obesity).
Speaker Bio:
Danny Abrams is co-director of NICO as well as a professor of Engineering Sciences and Applied Mathematics at Northwestern University. He holds a B.S. in Applied Physics from Caltech, a Ph.D. in Theoretical and Applied Mechanics from Cornell University, and was an NSF Math Sciences postdoctoral fellow as well as a Fulbright Scholar and James S. McDonnell Foundation grantee. Danny's research interests include the study of synchronization, mathematical geoscience, and mathematical modeling of social systems.

WED@NICO SEMINAR: Rosemary Braun, Northwestern University "The Scale of Life"
Northwestern Institute on Complex Systems (NICO)
12:00 PM
//
Lower Level, Chambers Hall

Speaker:
Rosemary Braun, Associate Professor, Department of Molecular Biosciences, Northwestern University
Title:
The Scale of Life
Abstract:
Living systems exhibit surprising and beautiful self-organization at all scales. At the atomic level, proteins self-assemble into macromolecular complexes. The function of these machines is orchestrated within the cell by regulatory networks, whose activity is in turn dictated by, and coordinated with, the cells environment. This coordination takes place across large spans of space and time: the size and lifetime of organisms as large as the blue whale. Populations and ecosystems of many organisms in turn exhibit remarkable emergent dynamics. Today, advances in single-cell assays enable us to probe the molecular state of every cell in a sample in high-dimensional detail. But is this the correct scale at which to probe living systems? What can we learn from this data, and how can we abstract from the microscopic details to macroscopic phenotypes? In this talk, I will discuss some of our recent work bridging the cell and tissue/organism scales, and discuss some challenges and opportunities for the future.
Speaker Bio:
Rosemary Braun is an Associate Professor of Molecular Biosciences, Applied Mathematics [ESAM], and Physics at Northwestern University. A theoretical physicist by training, she earned her PhD in Physics from the University of Illinois, followed by a Masters in Biostatistics from Johns Hopkins University. She completed her postdoctoral training at the National Cancer Institute (NIH) before joining Northwestern as a faculty member. Today, she works at the intersection of statistics, mathematics, and biology to develop computational tools for analyzing high-dimensional data. In addition to her Northwestern affiliations, she is also Associate Director of the National Institute for Theory and Mathematics in Biology, as well as external faculty of the Santa Fe Institute.
