The two main branches of my research are stochastic geometry and distributional approximation. I am particularly interested in studying various spatial random structures like spatial random graphs, random tessellations, birth-growth models in the presence of long-range dependence. Distributional approximation, especially by non-Gaussian limits like the Dickman distribution, form a central topic of my research. Some of my recent works concern Gaussian approximation for stabilizing functionals with long-range interactions, and degree distribution in scale-free inhomogeneous random graphs. More recently, my interests have also been in studying noise sensitivity in continuum percolation models.
