Previously, I was a Postdoctoral Researcher at RIKEN Center for Advanced Intelligence Project in the Data-Driven Biomedical Science Team headed by Ichiro Takeuchi .

I hold a PhD in Applied Mathematics. My doctoral thesis focused on the design and analysis of faster and safer optimization algorithms for variable selection and hyperparameter calibration in high dimension. I was supervised by Olivier Fercoq and Joseph Salmon at Télécom ParisTech, EDMH, Université Paris Saclay.
