Thordur Oskarsson, PhD

Program: Molecular Oncology

Research Program: Cancer Biology & Evolution Program


  • Overview

    Dr. Oskarsson’s research is focused on breast cancer metastasis. Particularly, he studies the molecular crosstalk between metastatic cancer cells and the microenvironment in secondary organs to determine how these interactions promote progression of metastasis and resistance to therapy. Dr. Oskarsson fills a unique niche in understanding mechanisms of metastasis and will be an integral part of the Cancer Biology and Evolution Program.
