Our Life Sciences Editors

Dr Pauline Addis, MSc, PhD

Dr Pauline Addis loves good science and good science communication. She obtained her BSc (Hons) from Imperial in 2003 and her MSc from Hartpury University in 2007, for which she was awarded the Dodson & Horrell trophy for top student. She then undertook her PhD at Newcastle University in equine biomechanics, investigating how changing mechanical properties of tendon with age affect horses’ gait. The PhD led to several publications, presentations at international conferences and public engagement events such as Bright Club. During her PhD Pauline gained a deep understanding of anatomy, physiology and how to gain the co-operation of an excitable foal. After graduating in 2012, she stayed at Newcastle, switching from horses to humans, and spent 11 years in the Faculty of Medical Sciences demonstrating the impact of medical research for two iterations of the Research Excellence Framework (REF). In this role, Pauline worked with researchers in areas from fundamental biology to public health, via cancer research, genetics and neuroscience, and therefore has an enviably broad understanding of a massive range of medical research. In 2023 she moved to the NIHR Innovation Observatory at Newcastle University, a national horizon scanning organisation. Here, she specialises in synthesising evidence from a range of sources and presenting it in formats ranging from peer-reviewed journals to Pecha Kucha. Pauline also acts as a peer reviewer from various journals and therefore understands the importance of submitting a clear, concise manuscript.

Dr James Allen, PhD

Dr James Allen is an experienced biochemist who headed a research group in the  Department of Biochemistry, University of Oxford, UK, from 2006–2011.

Dr Jay Freeman, PhD

Dr Jay Freeman obtained his BSc in Chemistry from York University and his MSc in Advanced Organic Chemistry from the University of East Anglia (UEA). His PhD research on the synthesis of derivatized amino acids and their use in the self-assembly of supramolecular transition-metal structures was conducted at UEA and the Karlsruhe Institute of Technology in Germany. For the next decade, he worked for a Cambridge-based independent drug-discovery company as a medicinal chemist, designing and synthesising kinase and epigenetic inhibitors, and then at University College London on the development of biopolymer-based drug-delivery systems.
