Nathan's Notes
Stanford dropout working on creating the shared autonomy for remotely teleoperatable humanoid robots. Interested in implementing machine learning models from scratch, developing creative hackathon projects, and speeding up model training/inference with FSDP, quantization methods, and low-level architecture design.

Work History
Stanford Artificial Intelligence Laboratory (SAIL)
Sep 2024 - Present
- Developing dynamics-guided diffusion policies for manipulation of deformable materials by leveraging a transformer as a dynamics model for latent autoencoder representations of camera point cloud.
- Generating data using a custom simulator built with Taichi for accurate and efficient physics-based simulations.
- Optimizing test-time FID results by applying gradients to guide diffusion policies, inspired by classifier guidance in diffusion models for image and video generation.
K-Scale Labs
May 2024 – Present
- Developed quantized OpenVLA for the open-source robot “Stompy” using bitsandbytes, focusing on CUDA integration.
- Led PPO and physics simulator development with MJX and JAX, exporting Flax models with Tensorflow.js for inference.
- Integrated quantization methods into PyTorch by coding at the Python/C++ interface with Pybind.
Stanford University School of Medicine
Sep 2023 - Dec 2024
- Developed deep learning models with Pytorch and Weights & Biases to identify Right Ventricular insertion points for AHA Segmentation model on cDTI MRI images.
- Created an annotation system using AWS S3 for efficient data management.
- 4th in lab’s team for MICCAI 2024 MRI Reconstruction Challenge. Utilized variable splitting with CG method for data consistency, adaptive algorithm unrolling according to sample rate, and prompt blocks according to sample distribution to reconstruct undersampled MRI images.
