PhD Student @ INRIA

Rohit Roy

I explore the intersection of topology and data — finding hidden structures in complex datasets through the lens of computational geometry. Currently in the DataShape team at INRIA, Sophia-Antipolis. I spent my early years building a foundation in probability theory at Chennai Mathematical Institute, only to get swept off my feet by topological data analysis during my Masters.
