Biology is replete with examples of dynamic self-assembly, organization and movement that span subcellular, cellular, and multicellular length scales. In these examples, chemical, thermal and mechanical cues guide growth, organization and size and then eventually form and function. Most of the focus has been rightly until now on elucidating the biological and biochemical underpinnings of biophysical phenomena. It is becoming increasingly clear that elasticity and fluid flow constitute an important and integral part of how single cells, organelles, and multi-cellular organisms function, grow and interact. Dramatic advances in microscale engineering and microscopy have provided us with new, powerful tools to explore these interactions at varied and length and time scales: thus, opening new avenues to understand these biological “systems” and engineer synthetic “life-like” mimics.

Our focus is to combine experiments with analytical models, phenomenological mesoscale theories and multi-scale Brownian dynamics and atomistic simulations to understand the single cell motility, collective motility and response to light in flagellated and ciliated organisms such as bacteria and algae. We are also interested more generally in the role of mechanics in biophysical problems such as active memory and persistence if strain in active systems, statistical physics of active filaments and mechanics mediated synchronization in active ciliary beds and carpets.
