TwinsUK researchers recognised among the world’s leading genetics scientists
25th June 2026 – by Aaruthy Suthahar
Six researchers affiliated with TwinsUK have been recognised in the 2026 Ranking of the Best Genetics Scientists in the World by Research.com, highlighting the global impact of their contributions to genetics research.
The annual ranking evaluates researchers based on their publication record and citation impact within the field of genetics, using a Discipline H-index (D-index) and data from established scholarly databases.
The recognised TwinsUK researchers are:
- Professor Tim Spector
- Professor Massimo Mangino
- Professor Kerrin Small
- Professor Jordana Bell
- Dr Pirro Hysi
- Dr Mario Falchi
Together, their research has advanced understanding of the genetic, environmental and lifestyle factors that influence human health, spanning areas including ageing, nutrition, metabolism, eye health, epigenetics and complex disease.
Their work has been supported by the unique contribution of TwinsUK participants, whose long-term involvement in research has helped create one of the world’s most valuable resources for studying the interplay between genes, environment and health.
Professor Claire Steves, Director of TwinsUK, said:
TwinsUK, based at King’s College London, has followed thousands of twins over more than three decades, generating insights that have shaped understanding of genetics, healthy ageing, the gut microbiome, cardiometabolic health and personalised medicine.
The recognition reflects not only the achievements of individual researchers, but also the collective efforts of the wider TwinsUK community, including participants who have generously contributed their time, data and biological samples to support scientific discovery.
Professor Kerrin Small, Deputy Director of TwinsUK, said:
According to Research.com, the 2026 ranking analysed more than 187,000 scientist profiles across all scientific disciplines, including 4,342 researchers specialising in genetics. Scientists were required to achieve a D-index of at least 40 and demonstrate substantial impact within the field to be included.
The TwinsUK team would like to extend its sincere thanks to all participants whose continued commitment makes this research possible. Their contributions have helped generate discoveries that improve our understanding of health and disease and continue to support world-leading research with global impact.
