Alain Filloux is a Professor in Molecular Microbiology at Imperial College London (UK) and is based at the MRC Centre of Molecular Bacteriology and Infection (CMBI) since 2007. His research focuses on bacterial pathogenesis, molecular mechanisms of protein secretion, biofilm formation, and regulation of gene expression, using the bacterial pathogen Pseudomonas aeruginosa as model organism. He has made relevant contributions to the area of secretion systems biofilm formation, c-di-GMP signaling, and type VI secretion system (T6SS) in Pseudomonas aeruginosa. He was Editor-in-Chief for FEMS Microbiology Reviews from 2013-2018 and is the Editor-in-Chief for npj Biofilms and Microbiomes. He is a member of the European Academy of Microbiology (2016), Fellow of the American Academy of Microbiology (2017) and Fellow of the Royal Society of Biology (2019). Juan L. Ramos is Full Professor at the Spanish National Research Council (CSIC in Granada (Spain). His research interest focuses on the biology and gene regulation of environmental Pseudomonas. He was editor for The Journal of Bacteriology (1998-2007) and from 2008 has been Associate Editor for Environmental Microbiology and EMI Reports. At present he is Editor-in-Chief for Microbial Biotechnology. In 2012 he was awarded the Jaime I Award for Environmental Protection and in 2013 he received the Lwoff Medal from FEMS. He is an elected member of the European Academy of Microbiology, Fellow of the American Academy of Microbiology and an elected member of the Academy of Science of Granada (medal 13).
