Research
At MAGI Lab, we develop AI methods that learn from structure,
connect information across modalities, and support reasoning that
can be examined and evaluated. Our work brings together geometric
learning, trustworthy AI, and scientific applications, with a
broader commitment to AI for Good.
Trustworthy and Agentic AI
How can AI systems reason over complex information while remaining grounded in evidence?
We study language models, retrieval-augmented generation, and
agentic workflows that help people work with complex scientific
and technical information. We are interested in connecting model
outputs to supporting sources, evaluating reasoning, and making
limitations visible to the experts who use these systems.
AI for Scientific Discovery
How can AI connect scientific data and domain knowledge to support discovery and decision-making?
Scientific problems require more than predictions: they require
reasoning across measurements, models, literature, and domain
constraints. We develop methods to support these workflows in
collaboration with domain experts. Our DOE Genesis Mission
project, Data to Decision, explores evidence-traceable AI
reasoning for nuclear waste repository safety assessments;
related work investigates AI-piloted critical mineral recovery
from spent batteries.
Medical and Multimodal AI
How can complementary sources of information help AI better represent clinically meaningful patterns?
We develop learning methods for medical images, clinical text,
and time series, with an emphasis on interpretable representations
and clinically informed modeling. In computational pathology,
our work explores how multimodal experts and concept-guided
learning can support pediatric brain tumor classification and
make model behavior easier to inspect.
Geometric and Topological Learning
How can the structure of data guide what a model learns?
Geometry and topology provide tools for representing shape,
relationships, and variation in data. We use these ideas to
develop structure-aware representations, implicit neural models,
and knowledge-distillation methods for visual and time series
data. Our goal is to build learning methods whose representations
reflect meaningful properties of the underlying problem.
