Hi! I'm a PhD student in the Machine Learning Department at CMU where I am fortunate to be advised by Pradeep Ravikumar and Andrej Risteski. I graduated from CMU with degrees in computer science and statistics & machine learning. Before entering grad school I spent two years as a software engineer at Google NYC where I worked on Search Research and Machine Intelligence.
I'm broadly interested in the theoretical foundations of machine learning as a basis for human-like intelligence; in particular, I focus on robustness, representation learning, and out-of-distribution generalization. I work to develop principled formal analyses of the statistical and algorithmic properties of these tasks and possible approaches to solving them.
Research/Mentorship Opportunities: I am always happy to discuss my research with students; if you are interested in collaborating, please do not hesitate to reach out. I am also available to give advice and feedback for those who are applying to undergraduate or graduate programs in computer science. If you are applying for a PhD in CMU SCS, I encourage you to sign up to receive feedback through the Graduate Application Support Program.
