Career Profile

A PhD fellow in Spatial Transcriptomics at CHUV/UNIL, developing methods for analyzing spatial gene expression and imaging data to understand immuno-oncology and clinical response.

I also enjoy contributing to open-source projects to promote accessible tools and knowledge.

Previously, I spent 3+ years in the pharmaceutical industry as a Biostatistician/Data Scientist.
