Spotlight On: Nicola Fletcher
I grew up in Dublin but moved to Wicklow with my family when I was a teenager. We traded city life for a smallholding that quickly filled with horses, sheep and a medley of homeless animals that we were delighted to take in, and I thrived in the rural setting. While I sometimes got side-tracked from my studies, I developed a strong interest in science during my secondary school years. In 1996, I began my academic journey with a BSc in Equine Science from the University of Limerick. I enjoyed my undergraduate years and made the most of the freedom university life offered including an eight month trip to Kentucky to work on a thoroughbred horse stud.
Although I initially did not see myself in research, my love of the laboratory classes at university led me to a job at the Irish Equine Centre’s virology department. There, I gained invaluable experience and developed a passion for viruses. While at the Irish Equine Centre, there was an influenza outbreak that I worked on, and we patiently isolated and characterised the virus using a range of techniques. This piqued my interest in research, prompting me to start a PhD at UCD under the mentorship of Prof Sean Callanan and Prof David Brayden in University College Dublin back in 2002. My doctoral research focused on developing an in vitro blood-brain barrier for studying feline immunodeficiency virus neuropathology. It was an incredible experience, and I even had the opportunity to travel to the Glasgow Veterinary School under a Royal Academy Scholarship and continue the project with my first postdoctoral position investigating FIV neurotropism, funded by Science Foundation Ireland and mentored by Prof Callanan.
I wanted to gain experience in human virology after my PhD. This led me to the University of Birmingham in 2009 for a postdoctoral research position, where, under the mentorship of Prof Jane McKeating, I discovered that hepatitis C virus (HCV) is capable of infecting the blood-brain barrier, which was the first demonstration that HCV replication is not restricted to the liver. I subsequently identified a novel mechanism by which viruses can hijack the inflammatory microenvironment to promote their own infection.
I thoroughly enjoyed my time at the University of Birmingham, where I honed my skills as a research scientist. I saw the impact that translational research can have while working with clinicians in the liver transplant unit at Queen Elizabeth Hospital. I realised the impact that a One Health approach to research could bring, so in 2014 I moved back to UCD to complete a degree in Veterinary Medicine. After qualifying as a veterinary surgeon in 2018, I moved to the Animal and Plant Health Agency (APHA-Weybridge) in the UK as a research pathologist, where I conducted research studies on important infectious diseases such as rabies, African swine fever, hepatitis E virus and tuberculosis and began specialty training in veterinary pathology. In January 2020, I realised a lifelong dream when I joined the School of Veterinary Medicine as an Ad Astra Fellow, meaning that I could build a research team focused on a One Health approach to zoonotic viruses and teach veterinary students across the veterinary programme, from first year physiology to final year pathobiology. The COVID pandemic meant that my research took a different direction to the one originally planned, but I established the first laboratory in Ireland for SARS-CoV-2 culture, at the UCD Veterinary Medicine Biosafety Level 3 Laboratory, and obtained funding to investigate a range of projects including neurological disease associated with COVID, wastewater surveillance, antiviral therapies and the first discovery of European deer with anti-SARS-CoV-2 antibodies, in the fallow deer population at the Phoenix Park.
Currently, I lead a dynamic team of researchers comprising two postdoctoral fellows, a research assistant, two PhD students and honorary member Noodle the poodle. Together, we adopt a One Health approach to investigate the complexities of hepatitis E virus, an emerging zoonotic viral disease gaining significance. What makes our work exciting is the array of cutting-edge technologies we employ, most of which are available at UCD. From soft x-ray microscopy to novel 3D cell culture techniques and High Throughput Sequencing methods, we use a diverse toolkit to answer our research questions. This interdisciplinary approach allows us to gain comprehensive insights into the virus and its interactions within the ecosystem. If you are interested in working with us or have a project idea, we are always looking for new team members.
I am passionate about my work and fully embrace my inner nerd, but it is outside of work where my passion for all things nerdy truly shines. I am an avid astronomer and own a collection of telescopes. I also indulge in what my team have dubbed "maximal tourism," seeking out adventurous experiences around the globe. Whether it is embarking on a safari in Tanzania, horseback riding in Arizona, or taming camels in Egypt, I relish the opportunity to explore and immerse myself in new cultures and landscapes.
