Researcher

Koki Nagano

Koki Nagano is a computer graphics and AI researcher whose work connects realistic digital humans with interactive systems. He helped develop facial-detail methods and generative avatars, then coauthored neural and Gaussian models for animatable heads. His accessible human-digitization research won the Best-in-Show award at SIGGRAPH in 2021, and his 2026 work included video generation and full-duplex speech-motion interaction. He is a principal research scientist at NVIDIA, where he focuses on human-AI interaction for agentic and physical AI.

Timeline

  1. 2015

    Realistic facial skin

    In 2015, he contributes to ICT Graphics Lab research that captures facial pores and wrinkles to make digital avatars more lifelike.

  2. 2017

    A USC PhD in capture

    At USC in 2017, he defends “Multi-scale Dynamic Capture for High Quality Digital Humans,” a PhD thesis on high-fidelity 3D human capture supervised by Paul Debevec. He earns a B.E. in environmental design from Tokyo Institute of Technology and works for Weta Digital and Meta Reality Labs in Pittsburgh during his PhD.

  3. 2018–2019

    Avatar systems at Pinscreen

    At Pinscreen, he coauthors paGAN in 2018, a generative avatar method for expression-controlled face imagery. In 2019, he presents personalized real-time avatars for virtual try-on at SIGGRAPH Asia.

  4. 2021

    A SIGGRAPH Best-in-Show

    His research on accessible photorealistic human digitization wins the Best-in-Show award at SIGGRAPH in 2021.

  5. 2023

    One-shot neural head avatars

    In 2023, he coauthors Generalizable One-shot Neural Head Avatar, a model that reconstructs and animates a 3D head from a single portrait image.

  6. 2024

    GAvatar from text prompts

    In 2024, he coauthors GAvatar, which uses a primitive-based 3D Gaussian representation and implicit neural fields to generate animatable avatars from text prompts. The method renders at 100 fps at 1K resolution.

  7. 2025–2026

    Avatar generation and interaction

    In 2025, he coauthors GAIA, which uses expression-conditioned Gaussians to generate animatable 3D head avatars. In June 2026, he coauthors DyaPlex, a streaming model that synchronizes speech and motion for dyadic interaction. In August 2026, he coauthors Grounded-Exo2Ego, a video diffusion model that generates egocentric video from exocentric footage with geometric anchoring and semantic grounding.

  8. As of October 2026

    Principal research scientist at NVIDIA

    His current research focuses on human-AI interaction for agentic and physical AI. He joins NVIDIA Research in 2020 after serving as a principal scientist at Pinscreen and is a principal research scientist there as of October 2026.
