Agastya Kalra

I am currently a Principal Engineer at Akasha Imaging, where I am also a founding team member.

My research interests lie at the intersection of computational imaging, multi-view geometry, and machine learning, especially in the context of visual diversity or robotics. I have published in NeuriPS, ICCV, and CVPR and am a co-inventor on more than a dozen patents in computational imaging.
