Leon Espinosa

Research Engineer

My scientific background is based on a thesis in cardiovascular electrophysiology, a post-doc at INSERM, and an industrial experience at Nikon France. These experiences allowed me to acquire a solid expertise in both scientific instrumentation and programming (Java, Python, R), enriched by the continuous training of the CNRS.
Since I joined CNRS in 2005, I have held management responsibilities of technological platforms in microscopy, image analysis and instrumentation, in particular at the Laboratoire des Rickettsies (Faculty of Medicine of the Timone) from 2005 to 2010.
In 2010 I joined the Laboratory of Bacterial Chemistry where I first piloted a common service dedicated to microscopy image analysis and high screening debit. My missions include the implementation of advanced techniques (FRET, FRAP, bi- photon, etc.), the development of free software for image processing, as well as the analysis and quantification of data for various research projects. I was Deputy Director of the laboratory (2012 2017), responsible for common services and HR management. From 2018 to 2024, I led a scientific services team dedicated to instrumentation and to the data analysis in microbiology (IAM team), composed of 5 permanent members. Within my team, I ensured the coordination of collaborative projects.
In 2025 I introduced a significant change in my career. In agreement with the laboratory I left the direction of the IAM team and joined the M3G team " Mathematical Modeling of the Microbiomes " led by Dr. Florence Bansept. Within the team the activities that have been entrusted to me are: software development for applications and daily management of the team (financial management, purchasing, reception of interns and students).
