I work at the interface of theory and observations with the aim of better constraining the cosmological models. I analyze multiple probes of the large scale structure to leverage their complementarity, resulting in robust and precise constraints on the model parameters. I primarily work with galaxy densities, weak lensing, and secondary anisotropies of the Cosmic Microwave Background and analyze their various cross-correlation statistics. On the model side, I work with analytical, simulation- and machine learning-based models for these cosmic probes. I earned my PhD from the University of Pennsylvania, following an undergraduate degree in engineering physics from the Indian Institute of Technology Delhi, and have since gained postdoctoral research experience at both Columbia University and Johns Hopkins University.
