Nigel Preston
Nigel Preston distinguishes his coverage through deep subject-matter expertise in human-powered vehicle racing, combining journalistic reporting with firsthand competitive experience that reveals technical nuances most reporters miss.
Competitor-turned-chronicler of HPV racing
Preston has participated in the Energy Breakthrough event since its inception, having been part of teams that secured line honours in 2000 and 2001 with Bendigo Senior SC. His reporting reflects an engineer's understanding of vehicle dynamics and racing strategy developed through decades of hands-on involvement in the sport.Architect of comprehensive HPV event coverage
As manager of the Energy Breakthrough website, Preston coordinates media documentation of the event lifecycle from entry announcements to post-competition analysis. He maintains a national HPV events calendar that connects regional competitions within Australia's human-powered vehicle racing circuit.Technical focus on vehicle innovation
Rather than general event reporting, Preston emphasizes engineering specifications and performance metrics across HPV categories, documenting advancements in aerodynamics and drivetrain efficiency. His coverage of the Australian HPV Super Series demonstrates specialized knowledge of racing regulations and competitive formats.Historical perspective on HPV evolution
Preston's documentation spans the Energy Breakthrough's development since 2005, capturing technological progression from early entries to contemporary designs. His firsthand experience since "catching the bug" from his older brother provides context for how human-powered vehicle engineering has evolved over two decades.4 more health journalists.
Abida Tasnim
Abida Tasnim is a health writer for The Daily Star who focuses on clear, practical guidance that helps readers recognise risks early and act before everyday illnesses turn into wider public health problems. She reports on infectious disease prevention, using measles coverage to show how outbreaks start with individual decisions and behaviours, not just hospital statistics. Her work explains what happens during an outbreak and then anchors the story in simple steps people can take, such as avoiding crowded places when symptoms appear, practising good hygiene, and seeking medical advice early. She writes direct, action‑oriented health explainers that turn clinical questions about contagion and disease burden into everyday choices. Across her beat, she stresses early recognition, timely care, and prevention as the foundations of healthier communities.
Adrián Carballo Casla
Adrián Carballo Casla stands out for turning complex cohort data on ageing into clear, food‑level advice on what older adults should eat to protect brain health and slow chronic disease. He is a researcher in nutritional epidemiology focused on ageing and chronic disease prevention and a postdoctoral researcher in geriatric epidemiology at Karolinska Institutet, writing health explainers for The Conversation. He reports on how diet quality, especially Mediterranean and Mind‑style patterns, shapes dementia risk, grey matter loss and neurocognitive ageing, and how healthy versus pro‑inflammatory diets alter multimorbidity trajectories. His articles translate findings on flavonoids, polyphenols, folate, omega‑3 fats and dietary nitrates into specific food choices and small, practical changes. Much of his coverage is anchored in his own studies on multimorbidity, high‑risk older adults and tailored dietary recommendations, often syndicated to other outlets.
Ahmed Elbediwy
Ahmed Elbediwy brings a lab-based understanding of cancer biology and clinical biochemistry to public-facing health reporting, linking drug mechanisms and molecular pathways to everyday choices about medicines and products. He writes for The Conversation on weight-loss injections, cancer overdiagnosis and anti-ageing supplements, focusing on obesity medicine, cancer signalling, screening trade-offs, skincare and supplement science. His pieces on GLP-1 drugs such as Ozempic, Wegovy and Mounjaro explain why some people do not respond, how gut hormones and appetite signals work, and where psychological support and nutrition fit alongside prescriptions. He co-authors explainers on cancer risk and overdiagnosis and on whether supplements can reverse ageing, separating established knowledge from emerging research. An award-winning senior lecturer at Kingston University, he favours clear, structured explainers, careful definition of key terms and evidence-based appraisal over hype.
Amanda Sheppeard
Amanda Sheppeard is a managing editor and health journalist known for long, detailed explainers that connect complex clinical research, disability policy and political narratives with the daily realities of doctors and patients. She works at The Medical Republic across editorial leadership and commercial content while reporting widely on medicine for its specialist titles. Her real beat spans autism, disability policy, autoimmune disease, infectious threats and system pressures in primary care and hospitals. She covers subjects such as autism diagnosis and the NDIS, rheumatology’s clinical shifts, weight-loss agents in rheumatoid arthritis, infection control, antimicrobial resistance and new modalities like CAR T-cell therapy and microneedles. She reports by doing the synthesis inside the story, linking trial design, molecular targets, funding rules and policy changes to concrete decisions and workflows in clinics and hospitals.
