I am an experienced computer graphics researcher and developer.
I am currently a research engineer at Meta AI.
I completed my PhD at Tel Aviv University where I was a part of the Computer Graphics lab,
followed by a post-doc at Laboratoire d'Informatique (LIX) at École Polytechnique near Paris.

My research initially focused on shape analysis, shape and image similarity, segmentation and shape matching. In recent years I have worked mainly on 3D reconstruction and generative AI of 3D shapes.

I also have prior experience in VFX production.

Professional Experience

2020 - Now
Research Engineer, Meta
In recent years I was a research engineer at FAIR / GenAI at Meta. Selected projects:
  • Contributed to Llama 3 and Llama 4 multi-modal post-training
  • Meta 3D TextureGen project (joint first author)
  • Meta 3D AssetGen
  • Replay dataset: aligned multi-modal multi-view videos for 3D reconstruction
    (joint first author)
Technical leadership of 3D shapes dataset management and curation:
  • Evaluation of datasets from external vendors
  • Ingestion and conversion of shapes in various 3D formats
  • Shape preprocessing and rendering setups
  • PBR materials manipulation and verification
Previously, I was part of Spark AR, developing 3D studio software that artists use to create 3D effects for mobile phones and headsets.
  • Incorporated real time location tracking simulation in Spark Studio
  • Worked on simulated environments in Spark Studio
2019 - 2020
Research Scientist, Shapes AI
Shapes AI was an early stage startup company that developed solutions in the space of 3D shapes and video-based visual reasoning. I led the research efforts in the 3D domain, which include generative modeling, point clouds processing, and 3D search.
  • Worked on generative modeling research.
  • Developed a deep learning method to clean up noisy point clouds.
  • Developed an end-to-end solution for generating thousands of textured shapes from a small set, which includes procedural modeling and texture generation.
  • Worked on 3D shapes search where the input is an image or a 3D shape.
2018 - 2019
Software Developer, DNEG
DNEG is a visual effects company in London. I developed tools for the "on-set" department which is responsible of taking reference footage on the set of a show.
  • Worked on tools for browsing massive sets of 100K+ images.
  • Developed a deep learning method to detect color charts in images.
  • Developed a deep learning method to remove noise artifacts from images.
  • Developing in C++, Python, and MEL script language.
  • Worked with Maya, Nuke, Alembic, libraw, OpenEXR, and other common tools of the VFX industry.
