Experience

  • Applied Scientist Intern at Amazon
    Mar 2026 - Present · 4 mos

    Working on wearable technologies and indoor relocalization research.

  • Engineering Intern - PhD at Ai2
    Jun 2025 - Sep 2025 · 4 mos

    - Curated a balanced subset of a 22M-sample remote sensing dataset using feature-aware sampling strategies to support high-resolution canopy height prediction. - Finetuned a large multi-modal geo-spatial foundation model (Satlas Pretrain) for segmentation task, reached comparable performance as SOTA baselines using significantly smaller dataset and less computational resources, provided invaluable insights to the development of the OlmoEarth foundation models.

  • Engineering Intern - PhD at Allen Institute for AI (AI2)
    Jun 2024 - Sep 2024 · 4 mos

    I work as a R&D intern at AI2's Wildlands team, mentored by Paul Albee and Jay Thiagarajan. Pioneered a novel representation learning approach utilizing ordinal contrastive learning and nearest neighbor search to estimate weights of combustible materials from waist-level top-down images, an area with limited prior research and no existing successful implementations Fine tuned DINOv2 on a small dataset, overcoming data limitations through multi-class classification data balancing with data augmentation techniques. Applied principal component analysis (PCA) for feature dimensionality reduction
