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.

Feb 2019: Morphing origami work accepted for publication in Physical Review Letters (PRL). We created a new origami-based pattern that can exhibit extremely tunable Poisson's ratio going theoretically from negative infinity to positive infinity as it folds and that can morph into a hybrid material system with re-programmable combination of contrasting metamaterials.
