I study how AI systems fail when surface-level sentiment masks deeper user intent. My research sits at the intersection of NLP, intent modelling, and LLM reliability — three preprints published on TechRxiv (IEEE) and SSRN, six deployed AI systems built from research to production.

Researcher. Builder.
System Thinker.

I am a CS graduate specialising in NLP research, LLM reliability, and the design of AI systems that go beyond surface-level language understanding.

My research investigates a specific failure mode — when AI systems respond to how something is said rather than what it means. Three preprints that formalise this gap and propose intent modeling frameworks that operate beyond sentiment detection.

Alongside the research, I build production systems that operationalise these findings — clinical NLP pipelines, hallucination benchmarking platforms, RAG systems with claim-level verification, and misinformation detection architectures combining transformer classification with real-time fact-checking APIs.

What My Research Is Actually About

Most NLP systems are built to detect sentiment. What they cannot do reliably is infer intent — the difference between someone saying "I'm fine" and meaning it, and saying "I'm fine" while meaning something else entirely. My research formalises this gap, identifies its failure modes, and proposes frameworks that treat intent as a first-class signal rather than a downstream assumption from sentiment.

CURRENT FOCUS
Applied NLP & LLM Systems

Studying failure modes in sentiment-aware systems, benchmarking LLM hallucination across model families, and building production-grade NLP pipelines grounded in published research frameworks.

A System-Level Framework for Sentiment-Aware Reflective Writing Systems: Modeling Temporal Emotional Patterns with Interpretability and Ethical Safety

This paper analyses the limitations of sentiment-based AI systems and proposes a multi-layer framework integrating pragmatic reasoning, temporal pattern recognition, and goal-aware intent interpretation for reflective writing contexts.

Beyond Surface Affect: Why Sentiment Detection Alone is Insufficient for Intent Interpretation in Human–AI Communication

This research formally distinguishes sentiment detection from contextual intent interpretation in human-AI communication systems, proposing a richer framework for understanding user intent beyond surface-level sentiment signals.

Comparative Sentiment Analysis of YouTube Transcripts and User Comments: Failure Modes and Interpretability in Public Discourse

This research presents a dual-model sentiment analysis system combining LSTM neural networks with VADER lexicon-based analysis to compare creator transcript sentiment against audience comment sentiment across YouTube content domains, revealing systematic divergence patterns and documenting domain-specific failure modes.

If AI Can't Handle "I'm Fine," It Can't Handle the Future
On the gap between semantics and pragmatics in conversational AI — why systems that parse words fluently still miss hedging, indirect refusals, and masked distress, and why that gap is a safety issue in mental health and education contexts, not just a UX one.
