I am a fourth year undergraduate student at UT Austin, advised by Greg Durrett, where I am a part of the TAUR lab (Text Analysis, Understanding, and Reasoning). I'm also affiliated as a part-time researcher with some cool folks at Scale AI.
My research focuses on Natural Language Processing and topics in natural language generation and model interpretability. I'm currently working on getting a better understanding for how properties of data affect what gets learned by different kinds of learning algorithms for generation. I also have done some work in understanding and improving RLHF algorithms (particularly focused on reward modeling and things like online vs offline supervision), efficiency in decoding algorithms, and using explanations to predict large language model out-of-distribution robustness.
Prior to research, I've also had the chance to participate in nearly 20 hackathons, and I've made a lot of fun and interesting projects.
Feel free to send me an email if you'd like to chat about data, RLHF, text generation, interpretability, or NLP in general! Likewise, if you're a high-schooler or undergrad who's interested in getting into machine learning / research, I'm always happy to give advice if you feel like I can be of any help.
