Guillaume Chero

Data Scientist

After several years in different research institutes worldwide as PhD student and data scientist, I decided to offer my skills to institutional and private projects. Interested in developing tools in R and Python, I am always happy to learn new methods and skills to stay at the cutting edge of the field. Don't hesitate to contact me to talk about your project: guillaumecherodatascience@gmail.com !
