I am a Senior Teaching Fellow on the MSc Cardiovascular and Respiratory Healthcare programme hosted by the National Heart and Lung Institute (NHLI).  Together with the Course Director and Course Administrator, I plan and organise all aspects of the programme and I work with our Module Leads and lecturers to develop and deliver innovative teaching and assessment methods.  I am Module Lead for the Research Project module and a personal tutor for postgraduate students. 

I studied Genetics and Zoology as an undergraduate at Swansea University before spending 2 years in industry developing a DNA based security system. In 2000, I moved to NHLI where I managed the departmental real-time PCR facility and began my PhD research supervised by Prof Sir Magdi Yacoub and Dr Paul Barton.  My PhD investigated the role of cardiac extracellular matrix - the non-cellular portion of the heart, often likened to the scaffolding of the tissue - in the development of heart failure and recovery from heart failure using left ventricular assist devices (a type of artificial heart).

Following the award of my PhD, I continued my research into the molecular mechanisms of cardiac recovery at NHLI before taking up a teaching role in 2019.  

I am currently working towards my Master's degree in University Learning and Teaching (ULT, Imperial College London) after completing the PGDip and PGCert in ULT.

Outside of work, I am a governor at a primary school with responsibility for safeguarding, curriculum, assessment and standards, and pupil voice.  I am interested in the promotion of science as a career for young women and have previously work with the WISE campaign (Women into Science and Engineering) giving TV and newspaper interviews (including the Sunday Times and Evening Standard) and was profiled in ‘One Hundred Faces of Modern Science’, part of Science Year (2001), a nationwide initiative to promote science in schools.
