Web viewer for Gaussian splatting NeRFs

An interactive renderer for Gaussian splatting NeRFs written in WebGPU.

Salts of highly fluorinated weakly coordinating anions as versatile precursors towards hydrogen storage materials

Published in Dalton Transactions, 2015

Application of a patented synthesis protocol to a number of borohydride compounds. My BSc thesis in chemistry revolved around synthesis of [Ph4P]2[Mn(BH4)4], discussed in this article.

DISK: Learning local features with policy gradient

Published in NeurIPS, 2020

Local features are difficult to learn because they are inherently discrete. DISK uses reinforcement learning to get stable gradients and learn the task end-to-end.

RayTran: 3D pose estimation and shape reconstruction of multiple objects from videos with ray-traced transformers

Published in ECCV, 2022

We use attention to pool information from multiple posed input views in a global voxel representation. This allows for 3d object detection, shape reconstruction, novel view synthesis and more. A key trick is to exploit the image formation geometry to restrict the attention matrix, making the approach scalable and robust.

GECCO: Geometrically-Conditioned Point Diffusion Models

Published in ICCV, 2023

We use continuous diffusion to generate 3d point clouds, both unconditionally and based on monocular images. We propose a novel scheme for image conditioning via projected 2d feature lookup and show benefits of continuous diffusion, such as efficient upsampling of point clouds and computing sample probabilities.
