About
Subhrajit Bhattacharya is a robotics and computational geometry researcher whose work spans trajectory planning, topological path planning, and multi-robot systems. He is perhaps best known for his foundational contributions to homotopy-class-based path planning, introducing frameworks that allow robots to reason about topologically distinct routes around obstacles — work that has accumulated over 300 citations across his 2010 and 2012 papers alone. His 2017 paper on generating dynamically feasible trajectories for quadrotors using safe flight corridors in complex 3D environments has become a landmark reference in aerial robotics, earning over 530 citations and influencing a generation of micro aerial vehicle research. Earlier in his career, Bhattacharya pioneered the design and motion planning of spherical rolling robots, a novel nonholonomic system, with related work attracting over 300 combined citations. His research extends to multi-robot coordination on Riemannian manifolds, tethered robot navigation, and decoupled path deconfliction for robot swarms. Across these domains, Bhattacharya consistently bridges deep mathematical theory — drawing from topology, differential geometry, and convex optimization — with practical robotic implementation, making his contributions both intellectually rigorous and broadly applicable.
