World AIDS Day: We have come a very long way but there is still much to do to protect those at risk

Professor Sarah Fidler

This festive period Three Wise Women from the Faculty of Medicine will be giving us the gift of wisdom.

While HIV is no longer the death sentence that it once was, lifelong treatment is still required and there is no cure – yet. Professor Sarah Fidler from the Department of Infectious Disease discusses how a new type of HIV treatment holds promise as a longer-lasting alternative to current complex drug regimens.


Despite extraordinary political and medical advances, HIV, the virus that causes AIDS, remains one of the world’s most serious public health challenges. Since its discovery in 1983 by researchers at the Pasteur Institute in France, 84 million people worldwide are estimated to have become HIV-positive and 40 million people have died from an HIV-related illness. Today, there are around 38 million people living with HIV globally, with 1.5 million new infections in 2021.

Advocacy and close collaboration between clinicians, scientists and the HIV-affected community has inspired and driven the research and drug development and access agenda. Without these close working relationships, the development of HIV treatments would have been markedly slower and many more lives would have been lost.

Dr Alejandra Tomas, Senior Lecturer at the Department of Metabolism, Digestion and Reproduction, explores new and emerging incretin-based therapies for managing diabetes.

Diabetes is a disease that has reached epidemic proportions, with millions of people dying or suffering from a myriad of associated complications. Given that cases are projected to increase worldwide over the coming decades – especially in low- and middle-income countries – there is an urgent need to develop and deploy effective treatments for the disease.

Balancing academics and athletics as a student-athlete

Joaquin Bello

In August 2022, fifth-year Medical student, Joaquin Bello, and his twin brother, Javier Bello, made history as England’s first-ever Commonwealth Games beach volleyball medallists. Joaquin reflects on his journey to becoming a professional volleyball player, and the challenges of juggling academic studies with sports stardom.

This summer I won a bronze medal at the 2022 Birmingham Commonwealth Games, the culmination of many years of hard work whilst balancing my studies with training. While I hope my dual-career is far from over, I wanted to reflect on my journey so far and the lessons that I have learnt along the way.

Food for thought: Experiences from Imperial’s Food Student Research Network Conference

Dr Aaron M. Lett, Director of the Food Student Research Network, providing a plenary talk and officially launching the Food Student Research Network.

Recognising the value of interdisciplinary learning, Imperial’s Food Student Research Network aims to bring together students from across the College’s faculties to enable the cross-fertilisation of ideas and research in fields relevant to food. Here, members reflect on the Network’s inaugural conference.

In September, Imperial’s Food Student Research Network hosted its first Annual Conference. Reflective of the ethos of the network, this conference was an event for students, led by students.

Providing the most comprehensive picture of COVID-19 infectiousness to date, recent research from Imperial College scientists offered new insights into how long people with COVID-19 are infectious for. Co-author, Dr Seran Hakki, outlines the challenges of collecting real-world evidence in the first-of-its-kind study.

In August, the ATACCC Study (The Assessment of Transmission and Contagiousness of COVID-19 in Contacts) published some of their findings in one of the world’s leading respiratory health journals, The Lancet Respiratory Medicine. Our study was the first to use real-life evidence from naturally acquired infection to assess the duration of COVID-19 infectiousness, its correlation with symptom onset, and how this affects the accuracy of lateral flow tests.

Can we save lives by deliberately infecting people?

In the middle of the pandemic, scientists intentionally infected healthy volunteers with SARS-CoV-2, the virus that causes COVID-19. John Tregoning, Reader in Respiratory Infections at the Department of Infectious Disease, explains why these experiments, and the volunteers who take part in them, are critical to modern medicine.

In early March 2021, in the middle of the COVID-19 pandemic, a surprising-sounding set of experiments were taking place. Researchers at Imperial College London (and separately at the University of Oxford) were deliberately infecting healthy volunteers with SARS-CoV-2. This was in fact the latest in a long line of controlled human infection studies – where volunteers are deliberately infected with an infectious pathogen under extremely controlled conditions.

The future of smoking: why are young people still picking up the habit?

The government is on course to miss its target of making England smoke free by 2030. Dr Charlotte Vrinten, Research Associate at the School of Public Health, highlights how this delay leads to thousands of adolescents taking up the habit in the meantime.


Tobacco smoking has been declining in the UK over the last decade, but there are still nearly 7 million people who smoke.  Smoking is one of the main avoidable causes of illness and early death, and costs the NHS £2.4 billion per year. In 2019, the government pledged to make England smokefree by 2030.  However, a recent independent review found that the government is on course to miss its 2030 target by seven years. (more…)

Medicine in the Mountains

In March 2022, a group of medical students undertook a research expedition to the Atlas Mountains in Morocco. Georgia Leggett, reflects on her experience summiting Mount Toubkal and the challenges that come with conducting research in such a remote environment.


Before starting at Imperial, I was fortunate enough to co-lead a couple of charity projects in Brazil, where my varied experiences sparked my interest in health care provision in remote and extreme environments. Applying for the Remote Medicine BSc was an obvious choice, as it provided the opportunity to integrate my love of travel and adventure into my medical degree, and in March 2022, seven other students and I had the opportunity to carry out a research expedition to the Atlas Mountains in Morocco as part of our BSc projects.

Consulting and involving the public in the first human COVID-19 human challenge study

How do you engage members of the public with medical research? Dr Emma Smith, HIC-Vac Network Manager, outlines how consulting the public was crucial during the world’s first COVID-19 human challenge study.


It is important that health and social care research aims to improve the overall well-being of the population, from advancing treatments for patients to helping us live healthier lives. People are at the heart of medical research and so engaging and involving them is an integral part of the research process and one that is mandated by most funders.

When we set up the world’s first COVID-19 human challenge study, acceptability of research to participants and society more broadly was particularly relevant because of the study’s ethically complex nature.

With volunteer participants being deliberately exposed to coronavirus (COVID-19) and the associated risk (albeit very small) of serious illness or death, the public’s perspectives were an important element of assessing if the study was acceptable and ethical (and was stated by the WHO1  as one of the key criteria for the ethical acceptability of COVID-19 human challenge).

Don’t let a fear of the unknown limit your ambitions – my experience of studying for a Master of Public Health during the pandemic

Graduating is a significant milestone, especially if your studies have been impacted by Covid-19.  Jasmin Adebisi, now an alumni of the Master of Public Health programme, shares what it meant to walk across the stage at the Royal Albert Hall.


Graduation represents the culmination of a journey and the attainment of a goal. It is an exciting period in any student’s life which brings a long journey of hard work to a close. Graduation day can be filled with an array of varying emotions, including feelings of joy, pride and contentment but also thoughts of anxiousness, worry and concern of what’s to come next.

Having been a part of the Covid cohort of 2021, I can say with confidence that I have also experienced these emotions during my time studying. Reflecting on the start of my journey, I was bursting with excitement on getting accepted to my master’s course but was also deeply concerned because of the pandemic and the future.
