Agentic AI for scientific and engineering design

Investigating how science-of-science methods can work with structured extraction pipelines, network analysis, embedding-based search, and domain knowledge to identify promising scientific and engineering opportunities. The work connects evidence across publications, materials, measurements, and device concepts while keeping early-stage technical directions deliberately high level.

Technology capability maps

Developing embedding models that represent design choices and technical attributes extracted from papers and patents. The research examines whether interpretable directions in these spaces align with measurable progress, expose important tradeoffs, and help predict how technological capabilities evolve across materials and device platforms.

Biomedical and health applications of network science

Applied network science, machine learning, and scientific-data pipelines to problems in single-cell genomics, wound-healing materials, neuroscience, and biological networks. The work ranges from robust cell-type identification and literature-scale synthesis to reproducible cloud workflows, showing how shared computational representations can support very different biomedical questions.
