Prof. Phanisri Pradeep Pratapa

Our research group is interested in designing futuristic

structures and
materials

drawing from the ideas of

lattice mechanics
geometry
origami engineering and
3D printing

Using these concepts, we hope to create structural/material systems with superior mechanical performance and multi-functionality that will have applications across many engineering disciplines.

Prof. Phanisri Pradeep Pratapa is an Associate Professor in the Department of Civil Engineering at IIT Madras.
