RESEARCH EXPERIENCE

MAY 2025 - AUG 2025 Amazon AGI Foundations Applied Scientist Intern

  • Contributed to a research project on next-scale prediction-based autoregressive generative models for high-fidelity image and video generation.
  • Developed novel training-free and training-based methods to scale autoregressive models at inference time, enabling higher-quality generation without full retraining.

AUG 2023 - CURRENT Virginia Tech Research Assistant and Lab Lead

  • Awarded FAL.ai research fellowship to work on image and video generation models.
  • Collaborate with Google to implement research findings in closed-source diffusion-based image generation models, leading to publications at CVPR 2024 and ICCV 2025.
  • Awarded Deloitte Research Fellowship to investigate mechanistic interpretability of LLMs; developed a method to discover and control implicit model behaviors by learning steering vectors that modify internal activations.
  • Led research on generative models, enhancing diffusion text-to-image, text-to-video, and interpretability methods.

MAY 2024 - AUG 2024 Adobe Research Intern in Video Generative AI

  • Engineered a data pipeline to leverage existing image-editing and synthetic datasets for training video models, overcoming the scarcity of labeled video data.
  • Enabled a state-of-the-art video model to perform complex semantic edits by successfully adapting image-based training techniques for video generation tasks.

PROFESSIONAL EXPERIENCE

NOV 2022 - AUG 2023 Lyrebird Studio Machine Learning Engineer
