Newcastle University

Introduction

As a clinical applied physiologist I joined Newcastle University in September 2009, having moved from London to Newcastle. My research interests include physiological, particularly cardiac responses and adaptations to ageing and lifestyle intervention in both healthy and diseased populations.
Before joining Newcastle University I was a member of Cardiovascular Research Group established by Prof David Brodie at Buckinghamshire New University. Since then I have collaborated with a team of cardiologists led by Prof Sir Magdi Yacoub and Dr Emma Birks from Harefield Heart Science Centre.

Roles and Responsibilities

To develop and implement an independent research programme looking at the effect of ageing, disease and lifestyle on cardiovascular function.

To provide physiological support for studies within the laboratory.

To support further development of the Physical Activity and Exercise Research Group.

Contribute to postgraduate teaching, supervision of postgraduate students, and development of specialist postgraduate modules.
