Research Abstract

My research focuses on understanding the mechanisms that drive metastatic disease to the brain. We have used next-generation sequencing technology to identify potential therapeutic drivers not just in brain metastases but also in meningiomas, and craniopharyngiomas. My hope is that the findings from our work will provide us with an understanding of the molecular pathways that drive brain metastasis, which will allow us to develop more rational therapeutic approaches for this common and devastating complication of cancer.
