What You'll Work On• Train and fine-tune state-of-the-art generative models for talking-head synthesis, audio-driven facial animation, and full-body avatar video (e.g., diffusion models, DiT, 3D Gaussian Splatting, GAN-based and transformer-based video generators).• Build and maintain the training, evaluation, and deployment infrastructure on GPU clusters (PyTorch, DeepSpeed, FSDP, Ray, Kubernetes).• Define and track quality metrics — lip-sync accuracy, identity preservation, expression naturalness, latency, and throughput — and drive measurable improvements.•
