DESCRIPTION:Speaker: Arnold JTM Mathijssen\nhosted by Edouard Hannezo\nAbst
 ract: Biological systems flourish through collective functionality\, by se
 lf-assembling into cells\, tissues\, flocks and parliaments. Understanding
  this multi-scale organization also lies at the heart of modern engineerin
 g and medicine: Pathologies can arise from deficiencies in collective func
 tionality\, while active and adaptive materials can be designed from contr
 olling systems out of equilibrium. In this talk\, I will overview our rece
 nt work on building first-principle theories\, numerical tools\, and exper
 iments for studying the fascinating physics of life. We will first focus o
 n reliable communication in ultra-fast biology\, exemplified by the discov
 ery of hydrodynamic trigger waves [1]. Second\, we will discuss bacterial 
 contamination dynamics\, which is enhanced by the ability of cells to swim
  against flows [2]. Third\, we consider the role of topology in biofunctio
 nality\, especially in active carpets like ciliary arrays [3]. These insig
 hts open up exciting new avenues towards unravelling synthetic and biologi
 cal active matter\, through collective functionality\, together. BIO: Arno
 ld completed his MSci in theoretical physics at University College London 
 (2012)\, where he was named Best Overall Undergraduate and 30 under 30 by 
 Scientific American. He then joined the group of Julia Yeomans FRS for his
  DPhil at the University Oxford (2016)\, specialising in biological physic
 s\, specifically in the hydrodynamics and non-equilibrium statistical phys
 ics of active matter. This work was awarded the Sir Sam Edwards PhD Thesis
  Prize. Supported by an HFSP cross-disciplinary fellowship\, he moved to t
 he lab of Manu Prakash at Stanford University\, where he currently works o
 n the physics of pathogens and ultra-fast biology. Outside the lab\, Arnol
 d is very enthusiastic about science communication. He worked as editor an
 d editor-in-chief of a student-led magazine\, and now he frequently organi
 ses family events\, school visits and science hikes. Please join! 1.Mathij
