I’m a final year Ph.D. student in Computer Science at the University of Washington, Seattle, advised by Prof. Ranjay Krishna and Prof. Alex Ratner. Before that, I was an undergraduate student in Computer Science at the University of Illinois Urbana-Champaign, where I was fortunate to be advised by Prof. Jiawei Han.

Research Interests: My current research interests lie in multimodal models and data-centric AI.

My research is supported by the following fellowships:

• 2024 Apple AI/ML PhD fellowship (Data-centric AI track)
• OpenAI Superalignment Fellowship

I was selected as

• the 2025 ML and Systems Rising Stars

I’m passionate about mentoring and teaching. I was

• co-instructor of CSE 455: Computer Vision (undergrad)
• TA of CS 344: Introduction to Data Management (undergrad)
• TA of CS 599C: Training Data Management & Weak Supervision (grad)
• mentor of CSE 492 R: CSE Group Research (undergrad).
• mentor of UW CSE Pre-Application Mentorship Service (PAMS) program

I’m happy to mentor a few students on research and especially encourage students from underrepresented groups to reach out. If you are a junior student and want to discuss research and/or look for advice, feel free to schedule a chat via this link.
