Sébastien Rochette

Data scientist and developer at ThinkR: Expertise, teaching and consulting in R.

More on me…

I love developing with R and I love the R community!

My experience allows me to work with people from a large panel of fields in life science and any field where there is data to explore and analyse. 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 work on anything related to R. I like to play with maps and spatial tools, especially when the field of use is not related to geographial data.
