Haithem's research focuses on reconstructing, simulating, and generating dynamic 3D worlds, with a particular interest in the intersection of reconstruction and generative modeling. His recent work spans scalable neural scene reconstruction, real-time sensor simulation, and 3D content generation. He obtained his Ph.D.

Ziyi is a Research Scientist in NVIDIA’s Real-Time Graphics Research group, with research focused on light transport simulation and differentiable rendering. Before joining NVIDIA, Ziyi completed a Ph.D. in the Realistic Graphics Lab at EPFL, advised by Professor Wenzel Jakob. A complete list of publications can be found on Ziyi’s personal website.

Sixu joined the Accelerators & VLSI Research (AVR) group in 2026, after interning with the group during the summers of 2024 and 2025. His research interests include digital circuits & systems, and neural rendering.

Before beginning his Ph.D., he worked in the High-Performance Computing Department at Sensetime Research from 2021 to 2022, where he focused on designing low-power, end-to-end simultaneous localization and mapping (SLAM) accelerators for edge AR/VR platforms.
