Colloquium
Self-propelled Topological Defects
Speaker: Julia M Yeomans (The Rudolf Peierls Centre for Theoretical Physics, UK)
तिथि और समय
अमूर्त
Active materials such as bacteria, molecular motors and eukaryotic cells continuously transform chemical energy taken from their surroundings to mechanical work. Dense active matter shows mesoscale turbulence, the emergence of chaotic flow structures characterised by high vorticity and self-propelled topological defects. I shall describe the physics of active defects, discussing active microfluidics, active disclinations and examples of topological defects in biological systems.
Short Biography
Julia Yeomans is Head of the Rudolf Peierls Centre for Theoretical 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 active matter and mechanobiology. Julia is a Fellow of the Royal Society was awarded the EPJE-de Gennes Lecture Prize. She has 4 daughters and enjoys hiking and orienteering.
