Reader (Associate Professor)

Dr Riaz Akhtar

Graduated from UMIST in 2003 with a First Class MEng (Hons) in Biomedical Materials Science with Industrial Experience. In 2007, he completed a PhD at The University of Manchester in ‘The micromechanical behaviour of bone’. Following this, he undertook a post-doctoral position investigating the micromechanical properties of soft tissue. In July 2008, Riaz was awarded a British Heart Foundation Advanced Training fellowship where he focussed on arterial stiffening and diabetes. He joined the University of Liverpool in October 2011 as a lecturer in Biomedical Engineering, and previously held an RAEng/Leverhulme Senior Research Fellowship investigating aortic diseases with novel approaches.

Senior Lecturer

Dr Jill Madine

Graduated with BSc in Biochemistry from UMIST in 2002, and completed a PhD in Structural Biology at University of Manchester in 2006. Jill has been researching the role of amyloid protein aggregation in neurodegenerative and cardiovascular diseases for 20 years, which has been largely funded by Alzheimer’s Research UK and British Heart Foundation. Her research group at the University of Liverpool has a wide interest in amyloid protein diseases and aortic pathologies and elucidating the factors that contribute to the pathogenicity associated with these diseases.

Consultant Vascular Surgeon (Honorary Professor)

Prof. Mark Field

Prof. Field started higher education at the University of Leeds in 1986 with a BSc Hon in Biochemistry and Pharmacology. He then completed a DPhil in Biochemistry at the University of Oxford in 1993. Following this training in research methods, he moved to the University of Nottingham to complete medical training (1993-1998), being awarded a BMed Sci (First class) and BMBS. Post graduate surgical training took place within the Trent Surgical Rotation when he completed his MRCS. Cardiac Surgery training took place in Nottingham, Sheffield and Liverpool and finished in 2009. He was appointed a consultant at Liverpool Heart and Chest Hospital in 2009, and is now an honorary clinical Professor at University of Liverpool.

Inter-disciplinary Research Group

Team Members

We are an inter-disciplinary research group spanning expertise in materials science, biochemistry, vascular surgery and applied mathematics. Our interests span a range of areas within cardiovascular medicine and science but are largely focussed on aortic dissection and ascending aortic aneurysms.

Clinical Member

Mr. Omar Nawaytou

Graduated from Cairo University Medical School in 1998. Appointed as a Resident in Cardiothoracic Surgery at Cairo University Hospitals 2000-2003 where he concomitantly completed an MSc. He was appointed as Assistant Lecturer, then Lecturer, in Cardiothoracic Surgery from 2004-2007 where he completed his Medical Doctorate (MD) degree. He moved to the UK in 2007 and successfully completed the Fellowship examination of the RCS (Eng). He was awarded the prestigious Ethicon Fellowship from the SCTS and pursued advanced training in aortic valve and root repair at Hôpital Universitaires St. Luc in Brussels under the mentorship of Prof El- Khoury. He held a Heart Research UK fellowship at Liverpool Heart and Chest Hospital (LHCH) in 2016, and was appointed as a Consultant Cardiac and Aortic Surgeon at LHCH in 2017.

PhD Student

Sarah Shirley

Graduated with a BSc in Applied Zoology from LJMU in 2001, Sarah went on to complete a BSc Clinical Science (Perfusion) at NESCOT and qualified as a Clinical Perfusion Scientist in 2004.  Since then Sarah has also completed a MSc Translational Cardiovascular Medicine at the University of Bristol (2019) and is a member of the Society of Clinical Perfusion Scientists Executive Committee (Sub committee Education and Training).  Over the years Sarah has developed an interest in perfusion practices for aortic surgery and became connected with LABB during her Masters.  She commenced a part-time PhD in October 2020 investigating the role of inflammation in acute Type A aortic dissection under the supervision of Dr Jill Madine while continuing to maintain her clinical perfusion practice.

Clinical Member

Mr. Amer Harky

Graduated from Hawler Medical University in Erbil, Iraq and awarded Membership of Royal college of Surgeons / England in 2015 followed by MSc in Advanced Surgical Practice July 2019 from Cardiff University / Wales. Amer is a speciality trainee in Cardiothoracic Surgery, based in Liverpool Heart and Chest Hospital and has a special interest in Aorto-Vascular Surgery.

Consultant Vascular/Endovascular surgeon

Francesco Torella

Francesco was appointed consultant vascular/endovascular surgeon in 2003. He works at the Liverpool University Hospitals and at the Liverpool Heart & Chest Hospital. He studied in Italy, Belgium and the United Kingdom and qualified in Medicine in 1992. He became a Fellow of the Royal College of surgeons of England in 1997 and subsequently trained in general/vascular surgery in Merseyside and Manchester. He was awarded his Doctor of Medicine postgraduate degree in Manchester with the thesis “Development and Evaluation of a Blood Transfusion Trigger by Near Infrared Spectroscopy”. He is a founding member of the Liverpool Cardiovascular Service, in which cardiac and vascular surgeons combine their skills to deliver treatment to patients with complex aortic disease.


Bojin Marinov

Bojin graduated with BSc in Biochemistry and Biological engineering from the University of Toulon in 2019, and then obtained an MSc in Molecular Biotechnology from the University of Birmingham in 2020. He has extensive experience in NGS sequencing, obtained during his full-time position as an Associate Practitioner working for NHS on the LAMPore project. His PhD project investigates the role of collagen degradation in dissected aortic tissue.


Martin Hossack

Martin studied Medicine with an intercalated degree in Biomedical Sciences at The University of Manchester (2003-2009). Then worked as a junior doctor in London and New Zealand before starting basic surgical training in Manchester in 2013, where he obtained his MRCS. Began higher surgical training in Vascular Surgery in Liverpool in 2015. Currently undertaking a PhD at Liverpool University investigating the biomechanics and biochemistry of the abdominal aorta under the supervision of Dr Riaz Akhtar and Dr Jill Madine.
