Sachin venkateshAbout

I'm Sachin Venkatesh, a first year physics graduate student at the Georgia Institute of Technology. My research interests include but are not limited to galaxies, stellar evolution and compact objects, especially their computational aspects.

I am currently working with Dr. Matthew Liska here at Georgia Tech, investigating the boundary condition problems of Black Hole simulations using H-AMR : A New GPU-accelerated GRMHD Code for Exascale Computing With 3D Adaptive Mesh Refinement and Local Adaptive Time-stepping. This would help us to largely reduce the repetitive simulations to be run by helping us increase the resolution and scale of the simulations. I have previously worked on halo formation history and determining their properties using machine learning at the Center for Computational Astrophysics, worked on using Gaussian ML to classify GRBs spread over 10+ classes at the National Astronomical Observatory of Japan, and have also delved into Gravitational Wave data analysis, Radio Astronomy, both instrumentation of a radio antenna to act as the template for a large array and also on the observation side as a member of the SWAN, India.

I'm also interested in the numerical/computational methods and technical advancements, especially of ML methods and LLMs. I'm keen on harnessign these methodologies to produce physics-informed ML models. Please reach out if you would like to talk about the same.

I applied to physics and astronomy programs and learnt a lot, especially after being rejected everywhere during my first cycle. And I've so much to share about the process and things that'd help yout to stand out. Therefore, if you have any queries, don't hesitate to reach out. Because, this was me last year "I am applying for Graduate Schools in Physics and Astronomy for Fall'22 and would be highly interested to know more about opportunities in different schools which work on the abovementioned research fields. So please feel free to reach out and share any suggestions, feedback, or guidance you may have for me. I would be extremely grateful for it!"
