Hi, I'm Donna.

I'm a Rackham Scholar and PhD student in the Computer Science & Engineering Division at the University of Michigan, Ann Arbor. I'm fortunate to be advised by Prof. Lin Ma, with whom I've worked ever since my undergraduate years — which is why I chose to continue my doctoral studies under his guidance.

My research lies at the intersection of database management systems and machine learning. Currently, I focus on optimizing index structures for large language models, including hierarchical indexing for faster, more scalable retrieval.

Before my PhD, I worked across industry — most recently at Google on modeling infrastructure, and earlier at Citadel, Tesla, NVIDIA, and Ford. I'm originally from the Bay Area, California.
