About me

My name is Aslane Mortreau. I’m a freelance data scientist and biostatistician with hands-on experience in both research and applied projects, particularly in the pharmaceutical and cosmetic sectors. I specialize in longitudinal data analysis, mixed models, and survival analysis, helping teams extract meaningful and robust insights from complex datasets. I’ve also developed tools like Triallytics, an interactive analytics platform designed to automate statistical analyses and make them more accessible to R&D teams. My goal is to bring statistical rigor and efficiency to clinical and efficacy studies by combining advanced methodologies with practical, user-friendly solutions.

Professional Experience

Data Research Engineer

August 2023 - September 2025

LVMH Recherche

  • Led statistical analyses of in vivo cosmetic efficacy studies, including longitudinal modeling (linear mixed-effects models), time-to-event analysis (Kaplan-Meier, Cox regression), and post-hoc comparisons via estimated marginal means.
  • Collaborated with clinical and regulatory teams to write and validate Statistical Analysis Plans (SAPs), handle missing data (MCAR/MAR), and ensure methodological alignment with claim validation and internal regulatory standards.
  • Developed modular and reusable R Shiny applications for non-statisticians to conduct automated analyses and visualize results.
  • Designed and implemented end-to-end automated statistical workflows (from raw clinical data to formatted tables/figures), reducing analysis turnaround time by >50%.
  • Actively contributed to cross-functional innovation projects, including the development of an AI-driven molecular substitution engine using graph embeddings (metapath2vec) for sustainable formulation strategies.
  • Tools and methods: R (lme4, survival, emmeans, Shiny), Python, Shiny, Docker, Google Cloud Platform, Git
