Marcel Mateos Salles
Hey! I'm Marcel, a junior at Brown University studying Computer Science and Economics. I'm a backend engineer and ML/AI/DL researcher with a passion for intersecting software engineering with cutting-edge research in ML/AI/DL. My current research interests lie in LLMs, model interetability, and self-supervised learning. This summer I will be interning at Pinterest as a backend engineer in the Infrastructure Organization and am currently a researcher with Prof. Randall Balestriero.
