His research focuses on the fundamental mechanisms that control organ-selective breast cancer metastasis and employs pre-clinical animal models and clinical material to identify molecular mediators and cellular process that promote breast cancer metastasis to distinct sites such as the bone, lung, liver and brain. He has expanded his research program to investigate colorectal cancer metastasis to the liver and solid cancer metastasis to the brain (lung, breast, melanoma).
