More on me…

My experience allows me to work with people from a large panel of fields in life science. I have a second degree diploma in laboratory techniques (microbiology, cellular biology, biochemistry), a master in agronomy and a phD in marine science. During my education, I have particularly focused on statistical and modeling methods applied to life sciences. After my phD, as a researcher in marine ecology, I continued to develop my skills in modeling, with a special attention to spatial datasets.
Today, I still work on my research projects, in collaboration with my ex-colleagues, to keep up-to-date on scientific questions. As a freelance, I propose my knowledge to universities, research laboratories and companies to help them dealing with their datasets through consulting and/or courses.
