Jérôme works with a team of scientists on aquatic animal health issues focusing on tilapia, carp and catfish: the three most important finfish species group cultured worldwide. Most of their activities focus on planning fish farms epidemiology and health economics data collection and analysis, development of web-based application for syndromic surveillance, training for good biological samples collection, implementation of biosecurity protocols and R&D with partners on rapid disease diagnostic tools of fish bacterial and viral diseases such as Streptococcus agalactiae or GBS, which is one of the major bacterial pathogen of tilapia and the newly emerging tilapia lake virus. Future work efforts are planned on the development of innovative veterinary solutions to reduce antimicrobial use (AMU) and antimicrobial resistance (AMR) in WorldFish focal and scaling countries in Asia and Africa.

Before joining WorldFish in June 2018, Jérôme lived in Australia for 10 years where he worked on multiple autogenous and recombinant vaccine research projects for warm water fish species with A/Prof Andrew Barnes at the University of Queensland (UQ) and he did his PhD (2011-2014) at UQ on an emerging bacterial disease (S. agalactiae) affecting wild fish species in Australia.
