Shreyas911/README.md

I am a Ph.D. candidate in Computational Science, Engineering, and Mathematics at the Oden Institute for Computational Engineering and Sciences, University of Texas at Austin. My research primarily involves solving PDE-constrained inverse problems in the context of paleoclimate reconstruction over ice sheets. I am broadly interested in data assimilation under uncertainty, machine learning, optimization, and modeling systems.

News

  • I will be working as a Deep Learning RnD Intern at Ansys for Summer 2024, a global leader in multiphysics simulation software. I will be working at the intersection of deep learning, generative AI, and computational physics.

  • I will be giving a talk on "Computational Science To Enable Digital Twins Of The Ocean" at minisymposium "Mathematical and computational foundations of predictive digital twins" at the 6th Annual Meeting of the SIAM Texas-Louisiana Section (TXLA23) to be held at the University of Louisiana at Lafayette, Lafayette, Louisiana.

  • I am going to Qeqertarsuaq, Greenland in August-Septemeber 2023 as part of the ACDC/GRISO summer school 2023! We will be based at the Arctic Station there.
