Computer Science undergrad at Caltech researching AI, computer vision, neural operators, and medical imaging. I recently presented my work at NeurIPS 2024, where I had the chance to meet some pretty remarkable people!
At the Anima AI + Science Lab, I'm working on projects at the intersection of AI and science! I've developed new neural operator architectures for medical imaging, introducing the U-shaped DISCO Neural Operator (UDNO), an in-place resolution agnostic replacement for the U-Net. Last year, I worked on an RL project, training asymmetric soft-actor critic models for high-speed autonomous racing. We utilized DINO foundation models to extract high-level semantic features like depth and object segmentation to develop a vision-only policy (no need for on-board GPS or LiDAR). The year before that, I imaged hidden fault lines under the nearby Long Beach at the Caltech Seismo Lab, writing a robust data processing pipeline to process 170 TB of seismic data from a large live seismic array of 5,000 sensors. I also worked on models for chemical drug analysis, detecting molecular composition from Raman spectra at the Wei Bio-Imaging Lab.
I also enjoy programming. I recently worked on a compiler written in OCaml with a friend.
I implemented a tiny autograd and NN library in Python. I wrote a game/physics engine in C (SDL2). I've implemented a heap allocator and virtual memory manager in C. I'm working on a marketplace for the Caltech community, written in Next.js (React) and Go (backend). In high school, I developed a minecraft server network, with game queues, multiplayer gamemodes, profile caching with Redis, and cross-server pub/sub messaging. I learned a lot about design and networking from understanding the game's packet protocol from wiki.vg. I also worked on Discord bots in Java and Python. At some point, I'll make a project page with nice graphics, but I'm currently busy with midterms and research.
