Research Interests

Our research group focuses on generating fundamental understanding in the area of suspensions of rigid and deformable particles (e.g. drops, elastic particles and vesicles), at the level of a few particles and also at high volume fractions. A detailed description of the research areas and projects in our group is available on our lab website.

All projects involve analytical, numerical and experimental components, and the experimental side requires, in particular, a significant effort in building new devices from scratch. So, if you like theory, or computation, or rigging up widgets, or perhaps even all of these, our group has some interesting projects to offer. Contact Prof. Ramachandran at for more details.
