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 Assistant Professor in the Department of Civil Engineering at IIT Madras.
