About me
I’m a Ph.D. candidate in the Department of Electrical Engineering and Computer Science at the University of California, Irvine (UCI), advised by Prof. Mohsen Imani. Before that, I did my M.S. in Computer Science at Texas A&M University with Prof. Xia “Ben” Hu and worked on knowledge-graph error detection and trustworthy data mining.
My research sits at the intersection of trustworthy & efficient graph learning/ML and LLM reasoning. I build methods that (i) unlearn data-specific information or de-bias models without full retraining/fine-tuning, (ii) make graph learning and hyperdimensional computing (HDC) more fair and robust, and (iii) enable LLMs to support efficient fine-tuning and low-resource inference.
Recently, I’ve been working on (first-authored):
-
Privacy-aware efficient LLM. [Under review]
-
Efficient LLM reasoning through KGs. Using high-dimensional representations for path retrieval/KG reasoning to reduce memory and computation while preserving reasoning performance. [Under review]
-
Fairness on graphs/ML/LLMs. [WSDM’26] [WWW’25 (short)] [CIKM’23 (short)] [Frontiers in Big Data]
-
Fairness-aware graph unlearning/machine unlearning. [CIKM’25]
-
Data-centric efficient graph learning/ML. Condensing graph/tabular data into tiny data for efficient training. [EUSIPCO’24] [WWW’25 (short)]
-
Other trustworthy ML directions. Interpretable dynamic GNNs: [IJCAI’25], anomaly detection on KGs: [EUSIPCO’23]
