Reading the past to predict the future.

Some disease risk is encoded in our cells before we are born. As a postdoctoral researcher at Cambridge University Hospitals and EMBL-EBI, I work on finding these early DNA methylation changes, understanding what they do and how widely they spread across the body, and predicting their impact on health.

Fig. 1 · One embryonic cell gains a methylation mark that all its descendants carry. Because this happens before tissues differentiate, the marked cell hitchhikes on normal growth and its descendants end up in several tissues across the body. That makes the mark discoverable in easily accessible tissues such as blood, which could be screened to infer an individual's risk. Over a lifetime, further changes in the affected cell population can push it along the path to disease, culminating in cancer or other diseases. embryonic markclonesubcloneindependent clone

About

Profile

I'm a computational biologist working on the epigenetic origins of disease. My ultimate goal is to establish how epigenetic changes and somatic mutations rewire the gene regulatory network to lead to disease, and to develop novel therapeutics that stop disease before the point of no return, as well as complementary diagnostic methods that precisely stratify eligible people ahead of them becoming patients. My research shows that DNA methylation changes acquired in the womb can lead to breast cancer several decades later, and that this risk can be detected in a blood sample taken at any point after birth. I'm now extending this body of work to show that the same mechanism underlies other diseases, and developing methods that use blood samples to predict risk in other inaccessible tissues.

I'm a postdoctoral researcher in the Behjati and Coorens groups at Cambridge University Hospitals and EMBL-EBI, where I'm building an analytical pipeline to find in-utero epigenetic changes that lead to cancer, developmental and neuropsychiatric disorders. I did my PhD with Peter Campbell at the Wellcome Sanger Institute, developing Memento, a Bayesian method that dates when a methylation change arose, to any point in a person's life from conception onwards, and establishing the breadth and importance of early embryonic methylation changes.

Before moving into biology I studied business and economics, and I've worked with the Sanger translational office on taking my research towards a spin-out.

Research

What I work on

Epigenetic origins of disease

Methylation is laid down in the early embryo, leaving cells with different starting points. I work on tracing which of these marks persist and contribute to cancer, developmental and neuropsychiatric disorders.

Dating when changes arise

I develop Bayesian models for large multi-omic datasets. I created Memento, which precisely dates each epigenetic change to a period in a person's lifetime, from conception onwards.

Non-invasive biomarker discovery

Because these marks are encoded in early development and inherited across tissues, I work on estimating disease risk from blood at any age, long before symptoms appear.
