Vilasini Tinnaneri Sreekanth

Welcome to my space! I am a PhD student at CosmoStat.
I’m passionate about unraveling the mysteries of the universe, with a focus on weak lensing, dark energy models, large-scale structure, numerical simulations, and machine learning. Weak lensing occurs when massive objects bend light rays as they pass between the source and the observer, due to their gravitational influence. This makes it a powerful tool for cosmology. My research involves likelihood-free parameter estimation using higher-order statistics. The goal of my PhD is to develop a hybrid approach for cosmological parameter inference. This method, based on theoretical predictions of higher-order statistics rather than N-body simulations, has the advantage of not requiring massive data storage for covariance matrices or the significant CPU/GPU resources needed for forward modeling. This makes it a highly competitive method for constraining cosmological models using higher-order statistics in future surveys. I’m also a member of the Euclid collaboration, so stay tuned to see how my work progresses!
I am one of the co-organisers of the Cosmostat Journal club. If you’re interested in giving a talk and meeting the CosmoStat group, feel free to contact Lisa Goh, Ezequiel Centofanti or me.
Beyond research, I have a deep love for traveling, exploring new cultures and local cuisines, learning about different architectural styles, and photography. Head over to my travel section for some great shots, or check out the "Potpourri of Thoughts" section to read about my latest adventures!
