Bio. I completed a D.Phil in Computer Science from the University of Oxford under the supervision of Dr. İsmail İlkan Ceylan and Prof. Thomas Lukasiewicz in 2022. My main research area is graph representation learning (GRL). In particular, I am interested in studying the strengths and limitations of GRL models, such as shallow embedding models and graph neural networks (GNNs), and proposing machine learning approaches with improved inductive capacity, interpretability, and representation power over relational data.

Current Work. I am currently a Program Scientist at the Learning Engineering Virtual Institute, working on applying large language models (LLMs) and structure-oriented machine learning approaches (e.g., GRL techniques) to improve middle school math education.
