Portrait of Gagan Bhatia — Understanding model behavior.

Artificial intelligence & natural language processingA little about me

01

About

I am a first-year PhD candidate at the Chair of Computer Science and Artificial Intelligence (CSAI), University of Technology Nuremberg, advised by Steffen Eger. My current research focuses on social biases in large language models, model interpretability, and chain-of-thought monitorability: understanding model behavior and what we can learn by monitoring the reasoning models produce.

Before starting my PhD, I completed an MSc in Artificial Intelligence at the University of Aberdeen (2024) and a BASc at the University of British Columbia (2022). During and after my undergraduate studies, I worked with Muhammad Abdul-Mageed’s Deep Learning & Natural Language Processing Group at UBC, contributing to Peacock, Dallah, Qalam, and FinTral — multimodal Arabic and financial large language models published at ACL and ArabicNLP.

My broader work spans multilingual generative-text evaluation, temporal reasoning and tokenisation in LLMs, and low-resource and Arabic NLP. My papers have appeared at ACL, EMNLP, NAACL, and ArabicNLP, and I collaborate with research groups across evaluation, temporal reasoning, and multilingual NLP.
