Dear Colleagues and Students,
You are cordially invited to UNAM Nanocolloquium seminars focusing on advancements in the field of nanoscience and nanotechnology. The seminars bring us the most recent developments in these exciting fields. This week’s talk will be presented by Dr. Julia Yeomans *
Title: “Dense Active Matter”
Date: April 26, 2019 (Friday)
Place: UNAM Conference Hall
Active materials, such as bacteria, molecular motors and self-propelled colloids, are Nature’s engines. They continuously transform chemical energy from their environment to mechanical work. Dense active matter shows mesoscale turbulence, the emergence of chaotic flow structures characterised by high vorticity and self-propelled topological defects.
The ideas of active matter are suggesting new ways of interpreting cell motility and cell division. I shall discuss recent results indicating that active topological defects may help to regulate turnover in epithelial cell layers and contribute to controlling the structure of bacterial colonies.
About the Speaker:
Julia Yeomans is Professor of Physics at the University of Oxford and Pauline Chan Fellow at St Hilda’s College. She applies techniques from theoretical and computational physics to problems in soft condensed matter and biophysics. Among her current research interests are how cells move and divide and how biofilms form. Julia is a Fellow of the Royal Society and was awarded the EPJE-de Gennes Lecture Prize.
