About Me

Hi! 👋 I’m a 4th year computer science student at UC Davis with a broad interest in computer vision & machine learning and how they can be applied to solve important societal problems.

I am an undergraduate research assistant at UC Davis focused on self-supervised representation Learning and adversarial robustness. Previously I worked on applications of ML in healthcare at Stanford. I also spent some time at Twitch/Amazon as an Applied Scientist where I worked on unsupervised and continual visual representation learning on streaming video data.

Experience

Twitch/Amazon 3X Internship 📺

  • 2022 (Applied Science): Developed unsupervised, continual learning framework on Twitch Streaming data. Framework allows for Machine Learning models developed by Twitch to be continuously and intelligently updated on new streams such that a model always stays up to date, learning new representations without forgetting old ones.

  • 2021 Fall (Software Engineer): Designed & developed an end-to-end, real-time Media-Analysis backend service integrated with both other AWS services and my trained Image Embedding to moderate Twitch’s 9.36M+ streamers’ content. Service is in production!

  • 2021 Summer (Applied Science): Developed a Twitch content representation Image Embedding trained using self-supervised learning. Improved prior method’s performance on downstream tasks such as Game Stream Classification by ~10%.
