About Me
I am a Ph.D. student in Computer Science at the University of California, Riverside, where I work with Prof. Amr Magdy in the Center for Geospatial Sciences.
My research sits at the intersection of geospatial AI, data management, information retrieval, and machine learning. I am currently interested in Geo-spatial Retrieval-Augmented Generation (RAG): combining spatial databases, semantic retrieval, and language models so systems can reason about both what a place means and where it is.
During my master’s study at Case Western Reserve University, I was fortunate to work in the database laboratory led by Prof. Yinghui Wu.
Research Interests
Geospatial AI · Spatial data science · Data management · Query optimization · Information retrieval · Machine learning
