Why I wear the rainbow lanyard (and why hockey is the greatest sport)

Katie Stripe

Katie Stripe gives a personal account of why she wears the rainbow lanyard to make herself visible to others who may need to see gay people doing normal things.


I could start by telling you what I identify as, but I don’t think that is important. The defining features of my character are more about what I am like as a person; sarcastic, grumpy, caring, funny, and what I do; I like to lift heavy weights, play hockey, take photographs, go on holiday and I did my first triathlon at 35 and now I am hooked (or mad). I am also a learning technologist and a learning designer, I build stuff online and develop learning materials and environments for students at Imperial’s National Heart and Lung Institute (NHLI). Having said all that I am writing this because as a gay member of the Imperial community I think it is important that I am visible to people who may need to see gay people doing normal things.

How we’re ensuring better care for older people with traumatic injuries

How we’re ensuring better care for older people with traumatic injuries
Originally publishing on the Imperial College Healthcare NHS Trust blog, consultant geriatrician Dr George Peck explains how the Trust is ensuring better care for older patients, and how trauma medicine is evolving to meet changing needs.


Bringing geriatric expertise to trauma care

As a registrar working with consultant geriatrician Dr Michael Fertleman, I was increasingly called to the trauma ward to offer geriatric assessments to patients who struggled with multiple issues. Best practice is to give a patient with suspected frailty a comprehensive geriatric assessment within 72 hours, but the volume of patients we receive who qualify has grown so much that this cannot be done without having a consultant geriatrician embedded in the service full time.

As a result, I became the first geriatrician in London to run a dedicated, embedded service in the trauma department. I will sit in the multidisciplinary team meeting with trauma surgeons, go on joint ward rounds with them throughout the week, and see major trauma patients whenever I am needed. I also help look after our surgical rehabilitation ward, which is for patients who are stable but require a longer period in hospital to recover. It is very rewarding to be able to offer continuity of care to our older trauma patients. (more…)

Exploring the evolutionary treadmill of genome defence

Dr Peter Sarkies looks at how evolution can quickly come up with new mechanisms to fight infection by adapting existing processes rather than inventing new ones.


It’s January and perhaps you’ve been hitting the treadmill in the gym in an enthusiastic bid to make good that New Year’s resolution to do more exercise.  To a primitive human, it’s hard to imagine a more ridiculous contraption – expending huge amounts of energy simply to stay in exactly the same place; but remarkably, this feature of a treadmill is very similar to some aspects of evolution.

The examples of evolution that are most familiar to people involve organisms adapting to their environment, with the long neck of the giraffe perfectly suited to reaching the best leaves as a famous example.  Probably the most active type of evolution by natural selection occurs in response to conflicts between organisms.  A good example of this is the response of species, like humans, to infection by pathogens like bacteria and viruses. Humans are engaged in a constant race to evolve new mechanisms to fight infection, because the pathogens themselves are able to rapidly adapt to become resistant to each new strategy that the host comes up with.

Thinking outside the ice box: revolutionising pancreas transplantation

Karim Hamaoui provides an insight into an innovative solution for the organ donation shortage – a technique that allows the pancreas to be preserved for longer and for better function.


The pancreas responsible for producing one of the body’s most important hormones: insulin. Since the first pancreas transplant in 1966, this procedure has revolutionised the treatment of type 1 diabetes. To date, pancreas transplantation is the only definitive treatment to render patients free from daily insulin injections and provide a better quality of life for these patients.

A key problem in the UK and worldwide is the limited supply of organs available and suitable for transplantation. The majority of pancreases used for transplantation in the UK come from a person who has died, and whose relatives have given permission for them to become an organ donor. To meet demand, the criteria used to identify suitable donors can be expanded from ‘ideal’ to ‘extended’ criteria. Extended criteria donors can also be euphemistically referred to as donors with ‘medical complexities’. They are normally aged 60 years or older, or aged over 50 years but with at least two of the following conditions: high blood pressure history, degree of kidney impairment, cause of death from a stroke. Unfortunately, complications are more pronounced for these types of organs. (more…)

It takes guts to fight obesity: how hormones could hold the key to sustainable weight loss

To mark National Obesity Awareness Week, Professor Tricia Tan explains how new research is harnessing the power of hormones to treat obesity more effectively.


Obesity has been an issue for centuries. However, it has transformed from a disease that once only touched a small number of people to a major health concern that currently affects one in four adults in the UK. As a result, obesity is now always in the news. Although many obese people are reasonably healthy, we know that obesity increases the risks of developing heart disease, diabetes mellitus (high blood sugar), cancer, respiratory problems (such as sleep apnoea and asthma) and arthritis. Obesity and its related health problems threaten to reverse the gains in lifespan that we have seen through the 20th century. So, how can we begin to tackle it? (more…)

Strength in numbers: monitoring of fungicide drug resistance with the help of 500 citizen scientists

In this post, Jennifer Shelton provides an insight into her PhD project which involves over 500 citizen scientists from across the world, in the hope of better understanding a species of fungus that is linked to disease.


It started by a poolside in Gran Canaria.

I was reading my book but thinking about the sticky films we use in the lab to cover plates of DNA that a former postdoc in my group had used to collect Penicillium spores for his study on the population genetics of ‘Alexander Fleming’s lucky fungus’. I’d already decided as part of my PhD to conduct a country-wide survey to determine background levels of Aspergillus fumigatus – a species of fungus – spores in the UK. I had put aside several weeks for driving around the country to collect air and soil samples, yet thoughts of a citizen science project kept buzzing. What if I asked individuals across the UK to collect samples of their local air on a single day, say summer solstice, and post them back to me?

Citizen science projects are increasing in popularity and rely on members of the public to voluntarily collect samples, process data or record observations as part of a research project. Some well-known examples include SETI@Home, which uses internet-connected computers to analyse telescope data in the search for extra-terrestrial life; Foldit, an online video game about protein folding and Swab & Send, a widespread swabbing exercise to identify novel antibiotics in the environment.

Tackling drug resistant infection through collaborative global action

Imperial’s Dr Esmita Charani and Dr Jamal Uddin, Child Health Research Foundation (CHRF), observing field work surveillance conducted by CHRF healthcare workers in Bangladesh as part of the demographic and disease surveillance initiatives aimed at reducing childhood morbidity and mortality.

Ahead of the recent G20 Summit in Buenos Aires, Professor Alison Holmes explained in an article for G20 Magazine why global collaboration is essential to minimising the impact of antimicrobial resistance (AMR) on healthcare.


The world faces the unprecedented challenge of drug resistant infection due to increasing AMR. Concerted global action is needed to address this pressing and alarming public health issue. Without a strong, unified response, the UN’s Sustainable Development Goals (SDGs) will not be met, and valuable progress will be lost.

The need for leadership

The continued inclusion of AMR in the G20 agenda, under the leadership of Argentina, is greatly welcomed. This year I was invited to speak in Buenos Aires on initiatives to optimise antibiotic use, at the International Congress on Infectious Diseases, co-hosted by the Infectious Diseases Society of Argentina. The ethos of shared learning and strong leadership was central in our discussions, and considered fundamental to effective action. (more…)

Noël hypothesis: my life as a medical statistician

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

Our final wise woman, director of the School of Public Health Professor Deborah Ashby, shares her joy of medical statistics, from working in neonatal research to taking on the Royal Statistical Society presidency. 


We Three Queens of Orient are…” came the dulcet sounds in the lead-up to Christmas. I looked up across the old Liverpool maternity ward, to see three colleagues singing and, channelling Morecambe and Wise, dancing towards me and my newborn daughter. The three women who had come to visit were all, like me, lecturers in medical statistics at the University of Liverpool, and that memory still brings a smile.

Although it was less glamorous than the alternatives, I’d chosen to give birth there, reasoning that if it went well, it didn’t matter where I was, but if not, I’d rather be somewhere with wide experience, actively engaged with and informed by research. In Liverpool, I had worked with the academic doctors from that maternity hospital, so knew I would get both. You might wonder why they had sought my advice, but research on babies involves analysing complex data on them, or designing studies to test competing treatments or strategies – all of which needs statistical skills along with clinical input.

Self-division: how I split my time between family life and cell cycles

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

Our second wise woman, research fellow Dr Alexis Barr, provides an insight into how she’s balancing family life with a research career.  


I never realised that when I started a family that other scientists would be so interested in my work/life balance. I am frequently asked how I manage a research career with bringing up two young children, aged two and four. Thankfully, it’s not as hard as you might think, but having a partner who shares the responsibility helps enormously.

I know why researchers are keen to talk about this as it seems to involve squaring a circle. Before I had children, I couldn’t easily conceive how working in a lab 8am – 7pm every day and often ‘popping in’ at weekends could work with caring for children. The problem is that it doesn’t, well at least not if you want to spend time with your children (which I do – not least because they’re hilarious). But it turns out that this isn’t a problem as there are other styles of working. Like most scientists I know, we love what we do so we’re quite motivated to find ways to make it work for us. (more…)

I can’t wait until I’m no longer waiting for the first Black scientist to win a Nobel Prize

The Wise Women

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

Our first wise woman, Dr Faith Uwadiae, highlighted success stories of Black scientists on her Twitter account every day throughout Black History Month 2018. In this post, she tells us what led to her taking action. 


The problem

I have been in the university academic system for almost a decade and in this time I have interacted with very few Black scientists. I have met a handful of Black PhD students and research assistants or technicians, one postdoctoral scientist, but sadly I’ve never been lectured by a Black scientist. When I attend scientific conferences or events I am frequently one of the few Black people in the room and often the only Black woman. In fact, Black professors are heavily underrepresented making up just 0.6% of UK professors, of which only 25 are Black female professors. Sadly, when people think about a scientist they don’t picture someone like me, i.e. Black, female and young, and instead default to the White, male and old archetype.

Scientists are much more diverse and I wanted to learn more about the stories of people like me. (more…)
