Our research program is focused on understanding how reciprocal communication between cancer cells and diverse immune and stromal cell types in the tumor microenvironment (TME) controls tumor initiation, progression, and metastasis, and modulates the response to therapeutic intervention. We employ a broad range of complementary experimental strategies to deeply interrogate the TME including the comprehensive analysis of patient samples (RNA-seq, proteomics, immune phenotyping, single cell analyses etc), mouse models of cancer, multi-modal in vivo imaging platforms, co-culture systems to mimic the TME, and diverse computational analyses. ...
Research projects
Tumor microenvironment
We currently have multiple projects focused on exploring the TME of primary and metastatic brain cancers, including analyses of diverse immune cell phenotypes, the blood and lymphatic vascular networks, and interrogation of the unique properties of the brain extracellular matrix. We are also fascinated by the dynamic evolution of the TME during cancer progression and metastasis in several tumor types, including breast, melanoma and lung cancer. Another major area of interest focuses on how different therapies alter the TME, and how those changes can consequently modulate therapeutic outcome. Our ultimate goal is to apply all of this knowledge to the clinic and develop targeted therapies that disrupt essential tumor-microenvironment interactions for the benefit of patients.
