Why I Left My PhD
Reflections on recognizing when a path isn't right and having the courage to redirect toward what truly drives you.

I'm a biomedical engineer from EPFL with a deep passion for tissue engineering and organoid biology. My research journey has taken me from mechanical engineering at the American University of Sharjah to stem cell bioengineering at EPFL and biomaterials at Harvard's Mooney Lab.
Throughout my master's, I deliberately worked across multiple labs, spanning developmental biology, microtechnology, organ-on-chip systems, and biomaterials, to build a holistic understanding of how we can engineer human tissue models.
Today, I'm focused on the computational side of organoid biology: single-cell analysis, machine learning for biological data, and building the tools that will help us extract deeper meaning from these remarkable model systems.
