Ph.D. Candidate at Carnegie Mellon University
Human-AI Decision Making for Engineering Systems

Hi, I’m Seongeun Park

Portrait of Seongeun Park

I’m a Ph.D. candidate in Civil and Environmental Engineering at Carnegie Mellon University.
I develop human-AI decision systems for complex engineering operations. My work connects procedures, incident records, design knowledge, and real-time conditions so that people can make decisions with evidence they can inspect and trace.

Design for Operability

Infrastructure operators and designers must reconcile procedures, system conditions, historical incidents, and incomplete information. I study how AI can connect these sources while keeping its recommendations understandable and accountable.

Operational Decision Support

Designing AI systems that help people interpret complex conditions and make traceable decisions in safety-critical work

Design for Operation

Helping teams turn early design concepts into operationally useful systems while preserving decisions, assumptions, and open questions

Connected Engineering Knowledge

Structuring procedures, equipment, incidents, and design choices as knowledge graphs that AI can retrieve and explain

Human-AI Trust and Evaluation

Evaluating how AI support affects consistency, workload, uncertainty, trust, and human responsibility

Procedure-to-knowledge-graph research project

2026

Nuclear Procedure Digitization and Knowledge Graph Structuring

At Idaho National Laboratory, developed a multimodal pipeline combining document layout detection and LLM-based extraction to transform nuclear operating procedures into structured knowledge graphs for the DOE Light Water Reactor Sustainability Program.

Water treatment system operations project

2025–Present

Human-AI Design Refinement for Water Systems

Developing a GraphRAG-based assistant for PFAS treatment systems that helps engineers refine process flow diagrams into P&IDs while tracking decisions, assumptions, and open questions.

Knowledge graph-based decision support project

2024–2026

AI Decision Support for Microreactor Operations

Developed BuildLink, a GraphRAG assistant that connects procedure and incident knowledge graphs with operator interfaces to support traceable decisions during remote microreactor operations.

Hanging object detection dataset for construction safety

2024

HangCon: Benchmark Dataset for Hanging Object Detection

Developed a dataset of 101,381 images to improve the detection of hanging objects on construction sites, addressing safety challenges in lifting operations.

Large language model construction accident prediction project

2024

AI-Driven Accident Prediction for Construction Safety

Developed a predictive model using fine-tuned GPT and saliency visualization to analyze 15,000 construction accident records. Achieved 82% accuracy in classifying six accident types, demonstrating AI’s potential to enhance safety management.

Tunnel construction activity recognition project

2023

Contextual Multimodal Recognition for Tunnel Construction

Developed an audio-visual multimodal model to accurately recognize and monitor concurrent activities of multiple equipment in tunnel construction projects. The model enhances operational efficiency by integrating spatial and temporal contexts, achieving an F-score of 96.3% in real-world data testing.

Construction worker activity recognition project

2023

Human-Independent Activity Recognition for Construction Workers

Developed a sensor-based model for recognizing worker activities without the need for individual re-training. Achieved 78.64% accuracy using a variational-denoising autoencoder, outperforming existing benchmarks.

Slip, trip, and fall hazard identification project

2023

Collective Sensing for Slip, Trip, and Fall Hazard Identification

Developed a data-driven approach to detect slip, trip, and fall hazards by analyzing workers’ loss of body balance using wearable sensors and GPS-based location mapping.
