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.

  • Jun 2020: PhD research scholar Anandaroop Lahiri was selected as one of the four finalists of the ASCE EMI 2020 Elasticity Student Paper Competition held virtually on 27 May 2020, for his work on "Bloch wave analysis of 1D rigid triangulated Miura-ori lattice".

  • 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.
