Faeze Ghorbanpour

I am a PhD candidate in Computer Science at the Technical University of Munich, advised by Prof. Alexander Fraser and affiliated with the Munich Center for Machine Learning (MCML). My work focuses on the Efficient and Generalizable Transfer Learning, post-training of LLMs, multilingual NLP, and applied NLP. I started my PhD at LMU Munich in 2023 and moved to TUM with my group in 2026.

During my PhD my research has developed along three threads:

Alignment and post-training — adapting language models for tasks where human judgments genuinely disagree, where there is no single ground truth to fine-tune against.
Multilingual NLP — studying how models represent meaning across languages and how to steer their internal representations toward more consistent behavior.
Evaluation and safety — measuring how dependable model outputs are and how closely model judgments track human ones.

A common thread across all of it is efficiency: reaching strong transfer while training only a small fraction of a model’s parameters.

During my PhD I was a guest researcher at the University of Copenhagen, working with Prof. Anders Søgaard, and earlier at the Max Planck Institute for Demographic Research. Before my doctoral studies I spent several years as an NLP Scientist, building and deploying production NLP systems.
