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. On the model side, I have worked with analytical models but am now starting to use more simulation- and machine learning-based models. On the data side, I primarily work with galaxy densities, weak lensing, and secondary anisotropies of the Cosmic Microwave Background. I obtained my PhD from the University of Pennsylvania and my undergraduate degree in engineering physics from the Indian Institute of Technology Delhi.
