Education

• PhD in Computer Vision, University of Cambridge, 2023 (expected). Funded by the ERC Grant Horizon 2020: Project Eyecode.
• B.Tech. in Information Technology, National Institute of Technology Karnataka, India, 2018.

Work experience

• Oct 2022 - Present: Research Associate at University of Cambridge
  • Supervisor: Dr Cengiz Öztireli
  • 3D generative modelling with pointclouds and/or implicit neural representations
  • Helped design and deliver L355: Machine Visual Perception
  • Supervising a year-long MPhil. and Part II project in generative modelling with diffusion methods
• Feb 2019 - Sept 2022: Research Assistant at University of Cambridge
  • Supervisor: Dr Rafał Mantiuk
  • Working to capture and render images on a novel multi-focalplane, stereoscopic, high dynamic range display. We aim to produce images that will successfully pass the Visual Turing Test.
  • Responsible for reconstructing HDR images and estimating per-view depth maps. MLE-based estimators obtained by assuming a statistical camera noise model produced the best HDR images. Preliminary results were presented at an ECCV workshop, with a more elaborate journal version currently under review.
  • Also worked on optical flow, differentiable rendering, neural view synthesis
• Sept 2020 - Feb 2021: Part-time project with Huawei Research, Munich
  • Exploring the effect of different tone-curves (encoding functions) on the performance of state-of-the-art Computer Vision methods.
  • Conducted an evaluation of state-of-the-art face and object detectors as well as optical flow with the help of a new adversarial illumination dataset. The dataset and preliminary study were accepted to be published in the Journal of Imaging Science and Technology (JIST).
• July 2018 - Jan 2019: Research Assistant at National University of Singapore
  • Supervisor: Prof. Gary Tan
  • Involved in the development of agent-based traffic simulator, at the Singapore-MIT Alliance for Research and Technology (SMART) Lab. Contributed to the first release of SimMobility.
  • Worked to improve the runtime performance of an on-demand vehicle controller that handles shared taxi requests. On average, the simulation time was reduced to a third of the original.
