Some of this work has been published in <a rel="external" href="https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.128.144501">Phys. Rev. Lett. 128, 144501</a>.</p> <h1 id="collective-motion-of-bacteria">Collective Motion of Bacteria</h1> <p>One of the long-term goals was to investigate collective motion of bacteria in these settings. As a first step, here’s a simulation I built using the <a rel="external" href="https://github.com/google/jax-md">jax-md</a> package—partly to test its cool features:</p> <video controls autoplay loop width="49%"> <source src="/videos/bacteria-jax.webm" type="video/webm"> Your browser does not support the video tag. </video> 2025-07-24T00:00:00+00:00 2025-07-24T00:00:00+00:00 Unknown https://ehsanirani.github.io/projects/rheology-active-soft-particles/
