About me
I’m a fourth-year PhD student at UC San Diego, advised by Berk Ustun. My research focuses on making generative models and ML systems more reliable, interpretable, and human-aligned.
My work includes:
- Augmented Generation Systems: retrieval-augmented generation (RAG) for LLMs, structured inductive biases for diffusion models
- Human-interactive Systems: concept-bottleneck models (CBMs), privacy-preserving models for healthcare
- Document Analysis and Security: adversarial robustness, graph-neural networks for document manipulation detection

Academic Service and Teaching
Graduate Women in Computing (GradWIC) Mentorship Director
I ran the GradWIC mentorship program. With over 150 participants, I match incoming students from underrepresented backgrounds with experienced graduate student mentors and supervise mentorship across all mentor pairings.
Teaching
I volunteered as a lecturer and teaching assistant for AddisCoder, a summer program that teaches computer science to high school students in Ethiopia.
I served as a teaching assistant for CSE258: Recommendation System and Web Mining, taught by Julian McAuley.
During college, I served as a Harvard Patel Fellow, the recipient of a fellowship that allowed me to work with teaching staff to support students of diverse backgrounds and work individually with students in an introductory computer science course.
