Ph.D candidate at IIIT-H (Aug 2020)
Research Scientist Intern at Meta Reality Labs (Aug 2022 - Jan 2023)
I am a third year Ph.D candidate at CVIT, IIIT Hyderabad, supervised by Dr. P. J. Narayanan (Funded by the KCIS fellowship).
Previously, I completed my MS by research at IIIT Hyderabad, which is also where I completed my BTech in Computer Science Engineering.
My research involves playing around with the light transport equation for real-time performance, differentiable rendering and neural rendering (in other words, I work on Computer Vision/Computer Graphics and Machine Learning/Deep Learning.).

Bringing Linearly Transformed Cosines to Anisotropic GGXACM SIGGRAPH Symposium on Interactive 3D Graphics and Games (I3D) 2022, PACM-CGIT, Best Paper Award
We present an extension to LTCs for anisotropic GGX, in the context of real-time analytic area light shading. Our approach robustly fits LTC matrices to anisotropic GGX and ensures artefact free rendering. The end result is a 84 LUT parameterized by the elevation and azimuth of view vector and the roughness in x and y directions.
Fast Analytic Soft Shadows from Area LightsEurographics Symposium on Rendering (EGSR) 2021, DL-only track
We present an analytical solution for soft shadows from area lights, which naturally produces noise-free renderings as compared to equivalent stochastic methods. A structured approach to analytically compute soft shadows from spherical projections of lights and occluders with any 3D shape and efficiently for convex 3D shapes.
A Flexible Neural Renderer for Material VisualizationACM SIGGRAPH Asia 2019, Technical Briefs
Photo realism in computer generated imagery is crucially dependent on how well an artist is able to recreate real-world materials in the scene. We propose a convolutional neural network based workflow which generates high-quality ray traced material visualizations on a shaderball, in real-time.
