Summary
Our bodies prevent the development of cancer through tumour suppressive processes, which also affect the outcome of cancer therapy. Programmed cell death (apoptosis) is one such process, and defects in apoptosis promote cancer development and impair the response of tumour cells to anti-cancer therapies. My laboratory uses molecular biology and cell biology approaches to investigate the mechanisms of cell death and tumour suppression, partnering with pharma to develop novel cancer therapies.

Summary
In humans, billions of cells will die daily as part of normal turnover in various organs. It is vital that dying cells are rapidly removed as their accumulation has been linked to autoimmunity and inflammation. To aid efficient removal of dead cells, dying cells can disassemble into smaller fragments for neighbouring cells to engulf. We aim to understand the machinery that controls how dying cells can disassemble into smaller pieces and their function in cell clearance and autoimmunity.
I am a cancer researcher trained in cell biology, immunology and molecular oncology. I made major contributions to the discoveries that defects in cell death can cause cancer, autoimmune disease and impair the response of cancers to chemotherapy. My current work aims to reach a detailed understanding of the molecular mechanisms of programmed cell death and to exploit this knowledge to develop novel therapeutics for cancer and autoimmune diseases that can directly activate this process.
Cancers arise as a result of the impairment of critical cellular processes following the mutation of important regulatory genes. I am a molecular biologist and I study how the proteins of the Bcl-2 family regulate apoptosis, a process of cell death essential to maintain homeostasis in multicellular organisms, with the aim of designing drugs to kill cancer cells selectively. I am also interested in discovering new genes involved in the development of cancer using new genomics technology.

Summary
Cell death is essential for our well being. As insufficient cell deaths can lead to cancers, promoting cell killing is a promising new avenue for treating this disease. However, current approaches are not fully optimal because we do not completely understand how the switch for cell death is flipped on. Our project seeks to answer this important question and we anticipate that a better understanding of this basic process will enable improved treatment for diseases such as cancer.
