After completing postdoctoral research in the Department of Cardiology at King’s College London, he moved from the bench into scientific publishing and worked at Portland Press and then at Springer Nature as an Editor in the BMC Series handling a portfolio of medical journals. Before joining PLOS ONE in July 2021, James was the Managing Editor of the British Journal of Cancer.

Marianne Clemence

Senior Editor


Marianne studied Biological Sciences at the university of Oxford and subsequently completed a Wellcome Trust-funded doctoral training programme in Infection, Immunology and Translational Medicine. Her research focused on characterisation of the polysaccharide capsule in Neisseria meningitidis, a leading cause of bacterial meningitis. After her PhD, Marianne spent some time working as a medical writer, supporting the development of publications in rare genetic disorders. She developed a particular interest in Open Access in the publication of clinical research, which led her to join PLOS ONE in August 2020.

Steve Zimmerman

Senior Editor


Steve received an undergraduate degree in Communication Studies from Nottingham Trent University and a master’s degree in Intelligent Systems from the University of Nottingham. He stayed at Nottingham to pursue a PhD in Psychology, using cognitive modelling to examine language development. After graduating, Steve took a lecturing position at the University of Derby and then moved to the US to become an Assistant Professor at Illinois State University. His research focused on the development of scientific reasoning. He then worked as a freelance copyeditor before joining PLOS ONE in 2022.

Jennifer Tucker

Associate Editor

Jenny obtained her PhD in Medical Studies, with a focus potential novel interventions in two toxicological models of Parkinson’s disease through the University of Plymouth, with a large portion of her research undertaken at Florida International University. Following her PhD, Jenny worked at the University of Bath investigating imprinted genes and lncRNAs in breast and colon cancer. She joins the PLOS ONE team in August 2023 with over two years’ experience in scientific publishing at Frontiers.

Johanna Pruller

Associate Editor

Johanna studied Biomedical Engineering (BSc) and Tissue Engineering and Regenerative Medicine (MSc) at the University of Applied Sciences Technikum in Vienna, Austria, followed by a Wellcome Trust funded PHD at King’s College London in Stem Cells and Regenerative Medicine, where she developed a gene therapy for the rare childhood cancer rhabdomyosarcoma. She then stayed at King’s for a post-doc and fellowship investigating neuromuscular diseases. During this time, Johanna got interested in the publishing world, and this led to her joining PLOS ONE in August 2023.

Life Sciences

Alejandra Clark

Division Editor

Alejandra was born and raised in Argentina. She graduated with a degree in Molecular Biology from Edinburgh University. Inspired by undergraduate lectures on the RNA world, she stayed in Edinburgh to undertake a PhD on the mechanism of mRNA localisation in Ilan Davis’ lab. Alejandra moved south to the University of Cambridge to work on the role of miRNAs in Eric Miska’s lab at the Gurdon Institute. Before joining PLOS in 2013, she worked as an editor for EMBO Reports in Heidelberg.

Miquel Vall-llosera Camps

Senior Editor

Miquel received his BsC in Biology from the University of Barcelona. In 2012 he completed a PhD in Ecology at the Autonomous University of Barcelona.
