# About me

I am a second year PhD student in Applied Mathematics at IMB (Univ. de Bourgogne, France) under the supervision of H. Cardot and S. Vaiter. My PhD aims at regularizing an inverse problem that arises in the cancer research field in order to estimate the quantity of certain types of cells inside a tumor. This involves constrained optimization and we focused the first year of the PhD on constrained Support Vector Regression.
