Studying the tumor microenvironment in GI cancers

Research Focus

Tumor microenvironment biology across GI cancers

Aging and microenvironment remodeling

We investigate age-associated rewiring of fibroblast and immune signaling to uncover mechanisms that can be therapeutically targeted.

IDH1-mutant cholangiocarcinoma biology

We develop mechanistic and translational models to define immune microenvironment vulnerabilities in this distinct GI cancer subtype.

Lab Strategy

Working to improve our understanding of GI cancers

Mechanism Discovery

Dissect stromal, immune, and microenvironmental pathways that drive GI cancers.

Model Innovation

Create clinically relevant models spanning pancreatic and biliary malignancies.

Translational Testing

Evaluate tractable targets to inform therapeutic development and patient benefit.
