Experience

  • DAVWA JEROLON EI

    CONSULTING AND AUDITS
    November 2022 - Today (3 years and 7 months)
    Paris, France
    Over the past year, I have launched my own sole proprietorship, while delving into in-depth research on causal mediation analysis with high-dimensional data, commonly known as big data. Simultaneously, I used the Python Django package to create my website and blog, DAVWA Blog, where I share articles on Marketing Mix Modeling. In parallel, I developed a web application with R shiny and the R Robyn package to simplify the execution of Marketing Mix Modeling projects.

    September 2020 - August 2022 (2 years)
    Paris, France
    During my experience as an ATER, I focused my research work on causal mediation analysis using survival data. I also dedicated time to writing, publishing, and presenting scientific articles. In parallel, I had the opportunity to teach at the DUT STID program at IUT de Paris Cité as a course instructor, covering topics such as Operations Research, R Programming, data analysis with R, and Data Mining. This experience was a rewarding opportunity to share my knowledge and contribute to the academic development of students.

    September 2017 - August 2020 (3 years)
    Paris, France
    During my PhD, I primarily focused my efforts on developing theoretical results on causal mediation analysis. In parallel, I developed an R package called multimediate, available on Github, which facilitates these analyses. My results paved the way for fruitful collaborations with psychiatrists and epidemiologists, where I applied my knowledge to projects related to breast cancer as well as the study of anxiety and depression. I had the opportunity to teach several courses at the DUT Informatique program at IUT de Paris Cité, including Mathematical Modeling and Graph Theory.
