Complex Systems Seminar Series Presents: "SARS-CoV-2 invasion dynamics and disease development: insights from viral sequences" (Click to View Video of Seminar) 

Katie Koelle | Microbiology and Molecular Genetics | Population Biology, Ecology and Evolution | Emory University

Date of Seminar:  October 20, 2022

ABSTRACT: The unfolding of the SARS-CoV-2 pandemic led to tremendous sequencing efforts, with tens of millions of viral sequences now publicly available on platforms such as GISAID for quantitative analysis by researchers worldwide. These sequences can be informative of the timing of viral emergence in regions, patterns of geographic spread, epidemiological dynamics,..... FOR FULL ABSTRACT AND EVENT LISTING CLICK HERE

Complex Systems Seminar Series Presents: "Promoting the use of agent-based modeling in scientific inquiry: a Learning Sciences approach" (Click to View Video of Seminar) 

Ümit Aslan - Learning Sciences, Northwestern University

Date of Seminar:  March 8, 2022

ABSTRACT: Agent-based modeling provides a powerful computational infrastructure to construct dynamic representations of scientific phenomena that can augment analytical models in unique and meaningful ways. However, although it is used extensively in the field of complex systems and embraced by social scientists, only a handful of researchers in natural sciences incorporate agent-based modeling components into their theoretical investigations.

Complex Systems Seminar Series Presents: "The Evolutionary Exploration of Emergent Execution: Genetic Programming and Weird Machines" (Click to View)

Olivia Lucca Fraser - Special Circumstances (research consultancy)

Date of Seminar:  December 7, 2021

ABSTRACT: The process of exploiting or "hacking" a software vulnerability can, in many cases, be understood as the process of discovering and then programming what Halvar Flake has called a "weird machine" -- a spontaneous virtual machine that supervenes on the intended finite state machine that the vulnerable software in question implements. A weird machine has ... FOR FULL ABSTRACT AND EVENT LISTING CLICK HERE

Complex Systems Seminar Series Presents: "Using Information Geometry to Find Simple Models of Complex Processes" (Click to View)

Mark Transtrum - Brigham Young University

Date of Seminar:  November 9, 2021

ABSTRACT: Effective theories play a fundamental role in how we reason about the world. Although real physical processes are very complicated, useful models abstract away the irrelevant degrees of freedom to give parsimonious representations. I use information geometry to construct simplified models for many types of complex systems, such as biology, neuroscience, statistical physics, and complex engineered systems. .......FOR FULL ABSTRACT AND EVENT LISTING CLICK HERE

 

Complex Systems Seminar Series Presents: "Dynamical system models for politics and voting" (Click to View)

Vicky Chuqiao Yang - The Santa Fe Institute

Date of Seminar:  October 12, 2021

ABSTRACT: The recent US political landscape brings many puzzling questions. For example, the two major parties have become increasingly polarized since the 1960s, while most voters maintained moderate policy positions. What can lead to the disconnect between the parties and the voters? Also, a sizable proportion, often the majority, of the voting population is uninformed about facts relevant to their voting decisions, such as policies proposed by the candidates. Can such a voting body deliver good collective decisions? In this talk, I give an overview of research projects that address these complex issues, which leverage dynamical-system models, empirical findings in psychology, and data analysis. .......FOR FULL ABSTRACT AND EVENT LISTING CLICK HERE

Duncan Watts | The Effects of Task Complexity on Group Synergy | April 15, 2021

Complex Systems Seminar Series Presents: "The Effects of Task Complexity on Group Synergy" (Click to View)

Duncan Watts - University of Pennsylvania:  Annenberg School of Communication and Wharton School of Business

Date of Seminar:  April 15, 2021

Abstract:  Complexity—defined in terms of the number of components to a problem and the nature the inter-dependencies between them—is clearly a relevant feature of all tasks performed by groups. Yet the role that task complexity plays in determining group performance remains poorly understood, in part because no clear language exists to express it in a way that allows for straightforward comparisons across tasks.  ........FOR FULL ABSTRACT AND EVENT LISTING CLICK HERE

Jon Zelner | Where models meet morality: What role should complexity science play in addressing racial and socioeconomic disparities in the COVID-19 crisis? | March 9, 2021

Jon Zelner, School of Public Health, University of Michigan

Date of Seminar: March 9, 2021

ABSTRACT: Socioeconomic and racial inequalities in infection and mortality have been key features of the COVID-19 pandemic in the United States. While identifying these disparities is critical, it has also become clear that we lack the theoretical and methodological tools to integrate the mechanisms generating these inequities into models of infectious disease transmission ...

James Koopman & Carl Simon | New data, models, and methods to guide SARS-CoV-2 vaccine design and vaccination programs that counter escape mutations | March 2, 2021

James Koopman Epidemiology, School of Public Health, University of Michigan; Carl Simon, Complex Systems, Math, Public Policy, University of Michigan

Date of Seminar: March 2, 2021

Abstract: Before the emergence of escape mutants that now threaten pandemic control, we constructed and analyzed the first model integrating immune waning and escape mutations. In the model, escape mutants were not problematic until a year into the pandemic. After they emerged, vaccination could worsen the pandemic. We examined four patterns by which existing escape mutants ... SEE FULL ABSTRACT AND EVENT LISTING HERE

Abstract: Consider a network of identical phase oscillators with sinusoidal coupling. How likely are the oscillators to globally synchronize, starting from random initial phases? One expects dense networks to have a strong tendency to synchronize and the basin of attraction .... SEE FULL EVENT LISTING HERE
