I qualified from the University of Wales College of Medicine in 2003 and became a Nephrology consultant at Wessex Kidney Centre in 2014. I completed a research MD in transplant pharmacogenetics from the University of Southampton and I am an active member of WKC research team. I am the clinical lead for Home Haemodialysis and the regional training programme director for renal. My area of clinical expertise is in Home HD.

Dr Robert Lewis


I graduated in 1984 from Westminster Medical School, now part of Imperial College London. I trained as a nephrologist in London, working at St Bartholomew’s, Kings College and Guy’s Hospitals. I completed my higher medical degree (MD) at Guy’s Hospital in 1996 and have been a consultant nephrologist at the Wessex Kidney Centre since 1997. I was Director of the service between 2001 and 2008 and took on the role again in 2016. My clinics are held at St Richards Hospital, Chichester and at Bognor Regis War Memorial Hospital.

My particular area of interest is early chronic kidney disease (CKD). I was founder member of the national CKD Strategy Group and helped develop the 2014 NICE guidelines for management of CKD in the UK. I authored a book “Chronic Kidney Disease: a guide for the non-specialist” in 2012. I have held executive committee roles with the Renal Association and British Renal Association and am currently working with NICE to develop clinical guidelines and quality standards.

I am married to a local GP and live with our two teenage kids (and Alfie the dog) in Old Portsmouth. Music is my thing; Beethoven, Wagner, Prog-rock, Hendrix, Blues, Hip-hop - don’t care as long as it’s loud.


Dr Amir Bhanji

Consultant Nephrologist


I completed my training in renal medicine in 2013. During my registrar training I completed a master degree in Health Policy, Planning and Financing. I started as a Renal Consultant at the Wessex Kidney Centre in 2014. I do all of my nephrology practice at the Queen Alexandra Hospital in Portsmouth. I am Consultant Lead for Haemodialysis programme that includes one hospital unit and eight regional dialysis units. Currently, I am working on the 10 year strategy for haemodialysis provision across Wessex, which may involve re-tendering of existing units.

I like to spend my free time with friends and family. I enjoy gardening and when I get a chance I will try and get out on my bicycle for a short cycle around the South Downs.

I trained in Southampton graduating in 1991.  My junior doctor training was divided between Portsmouth and Bristol, with a brief stay in Australia before specialist renal training in Portsmouth.  I completed a MD degree in cell biology in renal transplantation through Southampton University and started my consultant post in the Wessex Kidney Centre in 2003.  I was the service director for 8 years until 2016, but now focus on patient care and renal information technology (IT), and various management roles within the wider Trust.  My clinics are in Basingstoke and Alton for nephrology, CKD, advanced kidney care, haemodialysis and post-transplant care.  I cover the renal inpatients on the wards in Southampton General Hospital two weeks in ten.  Away from medicine I am a keen runner and am a season ticket holder at my local Premiership football team.

Dr Kirsten Armstrong

Consultant Nephrologist


I have been a Consultant Nephrologist at WKC since 2010 and at University Hospital Southampton since 2007, working full-time across both sites. I completed my undergraduate training at Kings College Hospital, London and undertook my Specialist training in South Thames. I completed a Clinical PhD in cardiovascular risk in patients with chronic kidney disease at the University of Queensland, Brisbane, Australia where I spent 2 years and have presented my research at national and international conferences. I have 8 first author publications related to my research. My PhD was awarded Dean's recommendation for University reading list.

My specialist interests are Transition and AKI and I am Clinical lead for both at PHT and UHS respectively. I am also lead for Clinical governance and Clinical effectiveness at PHT which is a rewarding although time-consuming part of my job. I have recently returned from an 8 month sabbatical in Melbourne and am keen to use the experience I gained there to help with further developing the transition service between UHS and PHT.

As much as I enjoy my work, time spent with my husband and 2 children provides a daily reminder that maintaining a good work / life balance is what it is all about - easy to say but hard to achieve!
