Dr Joe Smith is a new consultant at Devon Partnerships Trust, having completed their training in May 2024 at the Chelsea and Westminster in west London, and working more recently at St Mary’s, Imperial, until January of this year. Their current main role is Specialty Doctor in Gender Medicine, for the Laurels Gender Identity Clinic in Exeter. Dr Smith also teaches at undergraduate and postgraduate level across the MDT spectrum on LGBTQ+ issues, trans medical care and reducing health inequalities. The future of BHIVA, and the future of HIV care and research in the next three years, is inextricably linked to the current political and economic climate. In uncertain times, with funding streams threatened and key populations already feeling the impact, there is a danger of losing all the progress that has been made against HIV in the last 30 years, towards ending new transmissions and preventable complications by 2030. What is now needed is a quick-thinking, adaptable approach to building our own sustainability; this can be done by enlisting the help of passionate and talented people from across the globe, covering all areas – clinicians, scientists and social scientists, the voluntary sector, and most importantly patients – in meaningful collaborations. There are many parallels in the political conflicts affecting gender medicine, and likewise, it’s already having a knock-on effect on outcomes for our multiply-marginalised cohorts – many of whose care we share with HIV and GUM services. In their role as a BHIVA trustee, Dr Smith hopes to foster good collaborative, representative working between HIV/GUM and gender care, representing the southwest at a regional level, whilst also helping BHIVA to look outward to the world stage, and strive to find opportunity and hope in times of crisis. Dr Smith was elected in 2025 as a BHIVA trustee to serve a three-year term to 2028.

I am a new consultant working in genitourinary medicine and HIV in Norwich since November 2021, having completed my training at Imperial College NHS Trust in London.

I am a member of the BASHH HIV and BBV SIG. I have a passion for Quality Improvement and am a qualified Quality Improvement Coach. Having experienced HIV care in a tertiary centre within an acute trust in London, I am now working in a clinic for a large community trust and therefore have experience of HIV care in two very different scenarios within England, and the benefits and challenges of both. I plan to bring this knowledge to BHIVA as well as my enthusiasm for quality improvement and providing excellent care for all people living with HIV, independent of the complexities or challenges faced.

My experience in organization of a similar albeit smaller organization in Sri Lanka will bring new perspective to the committee. IMGs are increasingly important in the provision of health care in the UK and their representation in BHIVA will be mutually beneficial.

Dr Dami Collier is a Clinical Lecturer in the Department of Pathology at the University of Cambridge. Dr Collier is interested in viruses of global health significance. She has studied within-host evolution of both HIV-1 and SARS-CoV-2. In HIV-1, she has been particularly interested in independent replication of the virus in the central nervous system (CNS) and characterising the genotypic and phenotypic properties of these CNS viruses. To do this, Dr Collier set up a clinical cohort study of HIV-1 positive patients with mild-moderate neurocognitive disorder at the Africa Health Research Institute in Durban, South Africa. In addition, she have worked collaboratively with the Malawi-Liverpool Wellcome Trust and have access to over 100 paired plasma and cerebrospinal fluid (CSF) samples. Dr Collier discovered that although CSF escape is uncommon, genetically distinct, independently replicating viral populations can be found in the CSF. These viruses have adapted to the constraints of the niche in which they find themselves, for example, she found that there is heterogeneity of broadly neutralising antibody activity and affinity for CCR5 coreceptors in these viruses compared with plasma-derived virus. In SARS-CoV-2, Dr Collier has studied virus diversity within a chronically infected patient by NGS and discovered that the intra host viral evolution was driven by immune escape from neutralising antibodies in the absence of adequate B and T cell responses. This not only provided insights into the dynamic evolution of a virus thought to be slowly evolving on a population level, but turned out to be the blueprint for emergence of virus variants that threaten the success of vaccines and longer term control of the pandemic. Dr Collier was appointed as an BHIVA appointed trustee for a two-year term from 2025 to 2027.
