Personal profile

Research interests

Prabhakar Ranganathan leads the Complex Fluid Systems research group in the Dept. of Mechanical & Aerospace Engineering.

He is interested in understanding through modeling, simulations and analysis how micro-scale interactions determine the complex and emergent macroscale behaviour of complex fluid systems.

Systems of interest include active systems consisting of self-propelled particles, as exemplified by cilia and flagella driven collectively by protein motors, and suspensions, swarms and tissues of motile microbes, and also passive systems, such as solutions of flexible polymers.

The group also works on analytical tools and techniques for designing experiments to test theoretical models and for developing innovative applications of complex fluid systems.
