Poster by Davide at the Active Matter and Active Media Summer School 2022, Cargèse, France
Davide presented his work at the Active Matter and Active Media Summer School 2022 in Cargèse, France. His poster “A one-dimensional three-state run-and-tumble model with a ‘cell cycle’“, focuses on the modelling of the dynamics and life cycle of the Caulobacter crescentus with Fokker-Planck equations.
Sandrine Heijnen presented a poster at the Active Assemblies Symposium in Leipzig, Germany, 23th September 2022.
Sandrine Heijnen attended the Active Assemblies Symposium in Leipzig, Germany on the 21-23th of September 2022. She presented a poster titled “Emergent Collective Behaviours for Active Particles in Optical Landscapes” showing the recent development in her project regarding the behaviour of superparamagnetic particles in a light illuminated field. The symposium was host to a lot of interesting talks ranging from new experimental systems to how to solve computational tasks.
Carolina presents at the ISMC Poznań on the 23rd of September 2022
On the 23rd of September Carolina will present her work on microswimmers in colloidal arrays at the ISMC in Poznań, Poland. In her talk, titled “Confounding Interactions with Obstacles: How Colloidal Lattices Steer the Dynamics of Catalytic Microswimmers“, she will show how colloidal lattices self-assembled at a fluid-fluid interface can steer the dynamics of catalytic microswimmers hovering along the interface.
Presentation by Chun-Jen Chen at DPG Meeting of the Condensed Matter Section, 4th – 9th of Sep. 2022
On the 7th of September, Chun-Jen Chen gave a talk titled “Collective response of microrobotic swarms to external threats” during his participation of the 2022 DPG Meeting of the Condensed Matter Section in Regensburg, Germany. The 15-minute talk focused on the novel stratergy to implement extra feature into a collective social behaviour and corresponding experimental results with microrobotic colloidal particles. The talk also delivered prospective impact of such findings on microrobotic swarm design and undiscovered phase behaviours between collective behavioural states. The meeting gethered a wide range of bio-physists and active/soft-matter physists and trigged inspiring discussion across different projects.
You can find out more detail about the presented work as the contents of this talk was based on Chun-Jen and Clemens Bechinger’s publication at New J. Phys. 24 033001 (2022).
David participates in the Complex Nanophotonics Science Camp 2022 in Windsor, UK
Between the 2nd and the 5th of August David participated in the Complex Nanophotonics Science Camp in Windsor, UK. The Science Camp brought together 60 early-career scientists in the field of photonics but also science writers and editors in an unconventional format – mixing contributed and invited talks, seminars and debates – to present and discuss the latest research and future directions of the field in an open atmosphere and help developing the Complex Nanophotonics community. During this conference David presented a talk on “Elongated active particles in speckle fields“, the questions were many and the community was very interested in the topic. In the journey to Windsor, David visited Phil and Giorgio’s lab, which was a great opportunity to discuss with the other students in the groups.
Presentation by Liam Ruske at Current and Future Themes in Soft & Biological Active Matter, 5 August 2022
Modelling the Dynamics of 3D cell aggregates

Date: 5 August 2022
Time: 11:00 (CEST)
Place: Current and Future Themes in Soft and Biological Matter, Nordita
Abstract:
Multicellular spheroids are self-assembled balls of cells, typically hunderds of microns in diameter. They are important model systems for high throughput screening of the effects of mechanical or oxidative stress on tumors and for testing the efficacy of anti-cancer drugs. Gradients in metabolite concentration and the cell division rate across spheroids lead to gradients in activity, the rate at which the cells use energy to generate forces. This results in cell ordering and flows that can be described using the theories of active nematics. By comparing cell alignment profiles in experiments to model predictions, we can extract dynamical tissue parameters which are difficult to measure directly, thus establishing a link between 3D active fluids and the tissue-scale organization in biological systems.
Liam Ruske participates in Current and Future Themes in Soft & Biological Active Matter, 01-19 August 2022, Stockholm
Between the 1st and the 19th of August 2022 Liam participated in the Nordita workshop Current and Future Themes in Soft & Biological Active Matter. In his talk titled “Modelling the Dynamics of 3D cell aggregates” he motivated how cell divisions and death act as a source of active forces in cellular aggregates and how these processes can be incorporated into continuum models of tissues. Applying this model to 3D living cell aggregates (spheroids) not only allows the inference of dynamic cell parameters from experimentally measured cell alignment profiles, but more generally motivates novel mechanisms for controlling the alignment of cells within aggregates which has been shown to influence the mechanical properties and invasive capabilities of tumors.
David participates in the MoLE conference, 25-29 July, Donostia-San Sebastián
Between the 25th and the 29th of July 2022 David participated in the MoLE conference in Donostia-San Sebastián. The unexpected demise of Professor Juan José Sáenz, on March 22, 2020, has left his beloved family and friends in shock all over the globe. Following his spirit, MoLE conference 2022 was devoted to honouring his memory the way he would have liked: Appreciated colleagues and friends presenting and discussing their most recent advances, in both electronics and photonics. During this conference David presented a poster on “Elongated active particles in speckle fields“, where he had the chance to discuss the topic with a broad community of interested scientists.
