Biography

Ashok Venkitaraman is the Director of the Cancer Science Institute of Singapore, a Distinguished Professor of Medicine at the National University of Singapore, Research Director at the Institute of Molecular & Cell Biology, A*STAR, Singapore, and the Executive Director of the NRF’s National Initiative for RNA Biology & Its Applications. From 1998 to 2020, he was the inaugural Ursula Zoellner Professor of Cancer Research at the University of Cambridge and a Professorial Fellow at Pembroke College, Cambridge. He also directed the MRC Cancer Unit in Cambridge from 2006 to 2019, pioneering advances in early cancer intervention.

Lab Description

Professor Ashok’s laboratory is dedicated to unraveling the mechanisms that make certain individuals more susceptible to cancer, with the aim of developing innovative strategies to intercept cancer at its early stages. The team uses inherited mutations in the breast cancer gene BRCA2 as a model, as BRCA2 mutation carriers are highly prone to cancer. They were among the first to demonstrate that BRCA2 protects genome integrity to suppress cancer, laying the foundation for targeted therapies specifically designed for BRCA-deficient cancers.

At the Cancer Science Institute (CSI), the lab investigates the structural and biophysical mechanisms underlying BRCA2’s function, offering insights into how cancer-causing mutations disrupt these protective mechanisms. To develop advanced therapeutic strategies, the lab has created cutting-edge technology platforms that: (1) identify and validate therapeutic targets within complex pathways, (2) modify enzyme activity through regulatory protein interactions (known as allo-targeting), and (3) explore cellular signaling pathways using novel light microscopy tools. These technological advancements have led to the formation of multiple spin-out companies from Cambridge University and fostered strong partnerships with industry and venture capital. At CSI, the team leverages these tools to seek methods to delay or prevent cancer development in high-risk individuals, collaborating closely with Professor Ashok’s lab at the Institute of Molecular & Cell Biology at A*STAR.

Professor Ashok’s research spans from basic science to clinical applications, integrating diverse methodologies including molecular cell biology, single-cell and single-molecule imaging, structural biology, biophysics, and chemistry. His leadership and commitment to cancer research continue to drive advancements, pushing the boundaries of cancer science toward meaningful clinical impact.
