Research Associate
@ UKP TU Darmstadt

I am a research associate at the UKP Lab, TU Darmstadt, supervised by Prof. Iryna Gurevych. My research focuses on mechanistic interpretability of language models.

My research focuses on understanding the geometry of interventions and steering in language-model representations.

I completed my MSc in NLP at MBZUAI, where I was advised by Prof. Yova Kementchedjhieva and Prof. Kentaro Inui. My thesis explored how large language models can reuse previous computations to speed up text generation without losing accuracy.

During my undergraduate studies, I conducted research under Dr. Kiet Nguyen and Prof. Ngan Nguyen at the UIT NLP Group. My work focused on hate speech detection and Vietnamese NLP.

Besides, I am also a

Looking for PhD Opportunities in Mechanistic Interpretability

I am seeking PhD opportunities in the United States for Fall 2027 admission, with interests in mechanistic interpretability, language models, and AI safety.
