What we do

01
Mapping the Cancer-Associated Fibroblast Landscape
We explore the unique roles of spatially distinct cancer-associated fibroblasts (CAFs) in shaping the radiotherapy response of tumors.

Multiomics Analysis of Spatially Distinct Stromal Cells Reveals Tumor-Induced O-Glycosylation of the CDK4-pRB Axis in Fibroblasts at the Invasive Tumor Edge. Cancer Res. 2022 Feb 15;82(4):648-664. doi: 10.1158/0008-5472.CAN-21-1705. PubMed PMID: 34853070; PubMed Central PMCID: PMC9075699.
02
Exploring the Colocatome
We employ the ensemble of cell-cell colocalizations, known as the colocatome, as a spatial -omic tool to dissect the complex architecture of diseases, integrating patient-derived in vitro models with human histological specimens.

03
Mapping Metabolic
Niches
We explore the spatiometabolic dynamics of lung adenocarcinoma, identifying critical O-glycosylation hotspots that that fuel tumor survival against radiotherapy.
