Soft Matter and Complex Fluids Lab
We have a fairly self-sufficient bunch of essential facilities for students to work in their proposed research areas, while simultaneously relying on common facilities in the MME department as well as other central facilities on IIT Madras campus.
Here is an enumeration of major facilities in our lab. Please contact us if you wish to use any of them.
