Darragh Kerins

LLM engineer and NLP researcher actively building in clinical model reasoning, terminology specificity, and hallucination detection. Background in NLU evaluation design, multilingual transfer, and transformer fine-tuning at scale.

Research Intern – Clinical NLP & AI at HiTZ Research Centre, UPV/EHU (2025-11 – 2026-01)

• Designed an NLU evaluation framework across 216 LLM outputs, assessing Fidelity, Restructuring Quality, and Clarity on Spanish→English clinical text transformation
• Identified structural-semantic transformation confusion: models systematically replace specific clinical terms with vague superordinates; specificity preservation ranged from 13% to 57%
• Catalogued 127 hallucination errors across four categories; prompt architecture proved decisive, with instruction-following capability outweighing domain pretraining — highlighting core limitations of small models under constrained generation
