Executive Committee Members

SVT President  - Emma Waldegrave

Oxford University Hospitals NHS Foundation Trust 

I continue to work clinically and thoroughly enjoy my professional role, while also raising my two children aged 11 and 12.  

Having spent almost nine years on the Executive Committee in various roles such as Conference Secretary, BMUS representative and Vice president, I now step into my two-year tenure as President of the SVT. 

It is a great honour to undertake the role and I hope to make it a successful term with increased access to education and training for both junior and advanced practitioners alike among other goals.

I would like to thank my fellow committee members across all four committees for the role they undertake and their consistent hard work. Without the voluntary work of our committee members the SVT would not be the esteemed professional voice it is today. 


Vice President - Kamran Modaresi

London Northwest University Hospitals Trust

I have been involved in Vascular disease / Ultrasound since 1988 and have been a member of the SVT since the very beginning.

I currently work in the Vascular Imaging Unit at LNWUHT. Our unit falls under the same umbrella as Vascular Surgery and Interventional Radiology.  This interdisciplinary collaboration and work environment enables our Clinical Vascular Scientists to be an integral part of the decision making and treatment process for our patient group. I believe that this is the way forward for our combined societies.

I have previously held the post of treasurer and I am part of the Professional Standards Committee. I am honoured to be able to step into the Vice President’s role and look forward to supporting our Society with the help of all the Executive Committee members.

Outside of work I enjoy restoring and showing classic cars as well as gardening.

In 2001 I relocated “home” to Cornwall, working as a vascular scientist at RCHT for 20years before being appointed Lead in 2021.

Conference Secretary - Klaus Bond

Oxford University Hospitals NHS Foundation Trust

I am the Chief Vascular Scientist at Oxford University Hospitals NHS Trust, which is the hub for Thames Valley Vascular Network, and have been a member of the SVT since 1996. I have a chequered career spanning medical electronics and clinical engineering including researching and developing intrauterine foetal monitoring devices, hospital and community equipment management, and of course, vascular science.

My vascular career started in 1996 as vascular technologist employed to establish and run a new DGH Vascular Studies Unit starting out with a good old ATL UM9 machine set up behind a curtain in a day surgery unit. Learning the role in those days was challenging and predominantly self-taught with help from colleagues in other centres, and a handful of books! I will always be in debt to the Leicester team, particularly Tim Hartshorne and Abigail Thrush for allowing me to spend time with them occasionally to see how it was done.

I have a keen interest in training and education and am pleased to have been involved with the NSHCS and the STP since 2012, contributing to recruitment shortlisting and interviewing, and the recent curriculum review. I am proud to have played a part in training 6 STP trainees so far who have gone on to exciting careers. I am currently on secondment to the Buckinghamshire, Oxfordshire and Berkshire West (BOB) Integrated Care System (ICS) as their Healthcare Sciences Workforce Programme Director.

Other non-work-related interests include being a School Governor and Town Councillor.

I have been on the Education Commitee, had a previous stint on the Executive committee and I am now the Membership secretary.

Outside of work I am mother to 3 teenagers and 3 dogs all of which keep me very busy, not to mention a connoisseur of gin at weekends.

Alison Charig

I've been working in Vascular Ultrasound at Portsmouth Hospitals since 1988. I joined the Vascular Lab following research posts in Sheffield and Coventry. Originally part of the Medical Physics department, we now have a standalone Vascular Assessment Unit, which I had the pleasure of leading for over 15 years. I have now retired from my management position but continue to support the team by working in clinics for a few days each month. 

I have held various positions on the Education and Professional Standards Committees. I'm also a passionate supporter of quality improvement. As well as encouraging you all to engage with the IQIPS process, I represent the SVT on the national Clinical Advisory Group for Physiological Diagnostics Accreditation. Let me know if you have any IQIPS questions or need some encouragement to get started.

Outside of work I am learning what it is like to be retired. I have taken up upholstery and running, and occasionally even sit down with a book during the day time! I also enjoy spending time with my 3 grown up children.

Executive Committee Secretary - Janine Fletcher

University Hospitals Dorset NHS Foundation Trust

Originally from Northern Ireland I completed my undergraduate degree in Physiology at the University of Glasgow in 2010.  After various (non-scientific!) jobs I decided to go back to study for an MSc in Medical Diagnostics at Cranfield University, Bedfordshire. 

During this time I was accepted onto the STP as a trainee vascular scientist going straight on from my masters to start my vascular career at Royal Bournemouth Hospital in September 2013.  I was in the 3rd cohort of STP trainees so it was still a fairly new programme and not widely known about.

I became a fully-fledged vascular scientist in 2016, staying on in my department in Bournemouth where I still am today.  I am very passionate in my role as a vascular scientist taking an active part in the training of subsequent STP trainees and getting involved in departmental quality meetings.

After some delay (due to motherhood and Covid!) I finally passed my SVT practical exam in April 2021.  I am excited to be involved with the committee and learn the ropes as a non-portfolio member.

When I’m not at work I like to spend time with my husband and little boy.  I also enjoy playing netball and cooking when I get the chance!
