This thesis consists of research work in the broad area of soft condensed matter theory with a focus on active matter. The study of long wavelength, low frequency collective behavior of active particles (bacterial suspensions, ...

This thesis has been concerned with a few problems in systems driven at the scale of particles. The problems dealt with here can be extended and elaborated upon in a variety of ways. In 2 we examine the dynamics of a fluid ...

There has been much interest in the glassy dynamics of living systems at the scales of subcellular structures, cells and tissues. This has motivated theoretical studies on the approach to glassy behaviour in dense systems ...
