Building AI that can explain what it knows.

I work on trustworthy knowledge engineering, pairing large language models with knowledge graphs and ontologies so the result stays interpretable, evidence-checked, and ready to reuse.

Selected Projects

5 research systems
DOD-funded · social media + public health

SparKG

An automated system that turns social media into a real-time public-health monitor for emerging drug trends. It pulls posts, comments, and videos from Reddit, TikTok, and YouTube, then reads them with transformer models, OCR, and speech recognition to catch both explicit and subtle signals. Captions, transcripts, hashtags, and on-screen text merge into single records. A risk-scoring module flags high-risk or viral content, behavioral ontologies interpret substance mentions and psychological cues, and an interactive dashboard surfaces trends from daily spikes to long-range patterns.

Water Condensation

Neural networks that study how water and ice droplets form and behave in normal and microgravity conditions, where nucleation is hard to observe by traditional means. The pipeline processes large sets of experimental imagery to quantify droplet growth, coalescence, and freezing. Hand-annotated data trained a neural analysis interface (NAI) that detects and measures droplet dynamics, and a knowledge graph links the observed behavior to the underlying physics. It ships as a cloud-based, open-source module that accepts both image and video input, replacing a slow manual process with scalable analysis for aerospace and heat-transfer research.

PERSEUS

A method for building reliable ontologies from mixed sources while catching the hallucinations that large language models introduce. A cross-modal validation pipeline runs consistency checks across text, image, and audio, verifying LLM-inferred relations against metadata and semantic labels. An interactive interface lets people inspect, refine, and approve ontology graphs as they go. The feedback loop raised ontology accuracy by 11% over standard LLM-only methods and made multimodal ontology construction a transparent, user-guided process.

WiseOWL

An ontology validation tool that scores any ontology or knowledge graph across four metrics: entity-description quality, semantic connectivity between descriptions and entities, connection richness, and the depth and balance of the class hierarchy. It reports each score plus an average, and automatically flags any metric below 40%. Where it finds gaps, it suggests concrete next steps, such as clarifying descriptions, adding relational links, or rebalancing the hierarchy, so a raw validation result becomes a clear plan for improving reuse.

OLIVE

A semi-automated system that makes ontology building faster and easier to manage. Instead of experts defining every relationship by hand, OLIVE pairs large language models (ChatGPT and LLaMA) with the Neo4j graph database to generate and organize relationships from structured and unstructured data. People enter concepts or short prompts, and OLIVE assembles a knowledge graph showing how they connect, visualized live through WebVOWL. Experts review and correct results in the same interface. Validation with Protégé's reasoner and the OOPS! pitfall scanner confirmed logically sound output, and the workflow cut the time to build an ontology while improving how precisely relationships are captured.
