Hey, there!

I am working on taking over ML and AI by accelerating the tree traversals. Of course not, I’m just kidding! Or maybe not - you never know ¯_(ツ)_/¯.

My actual research interests span Parallel Computing, High-Performance Computing, Databases, and Compilers. I’m working on mapping applications to a particular tree traversal accelerated by Ray-Tracing cores of Nvidia GPUs. Prof. Milind Kulkarni is my Ph.D. advisor.

In the summer 2022, I interned at Katana Graph, where I had the opportunity to work with Roshan Dathathri on accelerating random walks on graphs. Before coming to Purdue, I did my undergrad in Computer Science & Engineering at the Indian Institute of Technology, Hyderabad, India. I was also at Simon Fraser Univerity, Vancouver, Canada briefly during the summer 2019 for MITACS internship. Thanks to Prof. Keval Vora, I had an amazing experience building a scalable solution to process computations on streaming graphs.
