Title: Universal laws and architectures: Theory and lessons from brains, nets, hearts, bugs, grids, flows, and zombies
Date/time: 1:30-2:30pm Friday May 15
Location: CS 105 (small auditorium)
This talk aims to accessibly introduce a new theory of network architecture relevant to biology, medicine and technology (particularly SDN/NFV and cyberphysical systems), initially minimizing math details. Key ideas are motivated by familiar examples from neuroscience, including live demos using audience brains, and further illustrated with examples from technology and biology. The status of the necessary math will be sketched in as much detail as time permits. Background material is in online videos (accessible from website above) and a recent blog post: rigorandrelevance.wordpress.com/author/doyleatcaltech. My research is aimed at developing a more “unified” theory for complex networks motivated by and drawing lessons from neuroscience, cell biology, medical physiology, technology (internet, smartgrid, sustainable infrastructure), and multiscale physics ,,. This theory involves several elements: hard limits, tradeoffs, and constraints on achievable robust, efficient performance ( “laws”), the organizing principles that succeed or fail in achieving them (“architectures” and protocols), the resulting high variability data and “robust yet fragile” behavior observed in real systems and case studies (behavior, data, statistics), the processes by which systems adapt and evolve (variation, selection, design), and their unavoidable fragilities (hijacking, parasites, predation, zombies). We will leverage a series of case studies with live demos from neuroscience, particularly vision and sensorimotor control, plus some hopefully familiar and simple insights from medicine, cell biology and modern computer and networking technology. Zombies emerge throughout as a ubiquitous, strangely popular, and annoying system fragility, particularly in the form of zombie science. In addition to the above mentioned blog and videos, papers  and  (and references therein) are the most accessible and broad introduction while the other papers give more domain specific details. For math details the best place to start is Nikolai Matni’s website (cds.caltech.edu/~nmatni/).
