Physics of Living Matter

Principal Investigator: Associate Prof. Anupam SENGUPTA

 

The Physics of Living Matter Group looks at LIFE, or as we put it, Living In Fluctuating Environments, using a cross-disciplinary approach. LIFE bridges the physics of FLOW (matter & information) and FORM (geometry, order & topology) to uncover biological FUNCTIONS (behavior & traits) in microbial systems.

We apply principles of Soft and Active Matter Physics and Modelling techniques to understand – in (micro) Biologically relevant settings – how microbes like bacteria, archaea and algae adapt to changes in their environment. Following are some of the representative researchers in our lab (details here):
1) Active microbial response under fluctuating environments
2) Topology mediated adaptive mechanics in soft and living matter
3) Biophysics of Transport & Sensing at the Microbiome-Human Interface

The Physics of Living Matter Group, embedded within the Physics and Materials Science Research Unit, and enjoys exciting interfaces with the Luxembourg Centre for Systems Biomedicine and the Luxembourg Institute of Health.
