Research Fellow

EPFL — NLP Lab • Lausanne, Switzerland

Researched commonsense knowledge representation and reasoning for NLG models under Prof. Antoine Bosselut. Designed an adversarial benchmark to stress-test how well evaluation metrics capture reasoning, and found that all 30+ SoTA metrics — from simple token-overlap ones like BLEU to model-based ones like G-EVAL — reward surface fluency over actual reasoning coherence.
