Julio Sempere

Julio Sempere is a Biochemist and Microbiologist working for the National Centre for Microbiology, Instituto de Salud Carlos III, based in Madrid.

Julio works in the Spanish Pneumococcal Reference Laboratory, in the Vaccine Preventable Bacterial Diseases Unit, evaluating new vaccine serotypes of the pneumococcus and the impact of vaccines in invasive pneumococcal disease. Julio researches bacteria biofilms, approaching new treatments against antibiotic resistant bacteria, and studies the interaction of pathogens with the immune system. His interests are in vaccines, clinical microbiology and immunology. 

Julio is a Madrilenian (born and bred in Madrid) and since watching Grey’s Anatomy, he’s wanted to become a scientist. Julio also enjoys cycling and running, and before the pandemic, he used to love going to the gym.

Björn Meyer

Björn Meyer, originally from Germany, is a virologist working in the Viral Populations and Pathogenesis Unit at the Institut Pasteur in Paris, France. 

Since the Covid-19 pandemic began, his research has focused on SARS-CoV-2 infected cells and what happens between cellular and viral proteins. Björn uses these interactions as starting points to target events for antiviral strategies specifically. He is also part of a therapeutic task force that develops assays and drug-screens to test new therapeutics (small molecules, biologics, antibodies, etc.) from academic and industrial partners. 
Outside of work, Björn makes the most of living in France — enjoying food and wine with his partner Kerri.

Faith Uwadiae

Faith Uwadiae is a Postdoctoral Research Fellow at the Francis Crick Institute in London. Her research is within the field of immunology and focuses on understanding the link between malaria and a type of cancer called Burkitt’s Lymphoma. She started her scientific career by pursuing a BSc in Biochemistry at King’s College London, before undertaking an MRes in Biomedical Research and a PhD in Immunology, both at Imperial College London. 

Currently, Faith is also an Early Career Representative for the British Society of Immunology’s Forum, working to raise issues and ideas to create policy change to shape UK immunology. Faith is passionate about improving racial diversity in STEM and does whatever she can through university and public engagement lectures, events, articles and social media. 

Outside of work, Faith spends her free time doing science in other ways: homebrewing beer and baking with a blog to document these food adventures. She is also obsessed with podcasts and recently became a lockdown cyclist – and she loves it.

Andrea Mazzella

Dr Andrea Mazzella, MRCP (UK), is a Research Physician working in the NIHR Guy’s and St Thomas’ Biomedical Research Centre, and one of the investigators of three Phase III clinical trials investigating the Janssen, Novavax and Oxford/AstraZeneca vaccines for Covid-19. His role involves discussing the trials with volunteers, assessing their eligibility and conducting follow-up and pharmacovigilance with hundreds of trial participants.

After qualifying from medical school in Italy with an Erasmus exchange programme in Spain, Andrea moved to England to work as a doctor in the NHS. Once he completed Core Medical Training, he studied at London School of Hygiene and Tropical Medicine for a master’s degree in Epidemiology. It was during this year that the COVID-19 pandemic unfolded; he graduated and decided to join the team of researchers working on COVID-19 vaccine clinical trials.

Andrea grew up on a tiny island in the Mediterranean and loves returning home and sailing. He has a geeky passion for linguistics and is powered by dark chocolate and nonna’s struffoli.
