I am Ilias Ftouhi. I defended my PhD at Sorbonne University in Paris in 2021 under the supervision of Professors Jimmy Lamboley and Antoine Henrot.
I am currently an Alexander von Humboldt postdoctoral researcher hosted by the Chair for Dynamics, Control, Machine Learning and Numerics.
I am interested in theoretical and numerical study of shape optimization problems and the use of deep learning techniques in solving inverse problems.
PhD Thesis: Blaschke-Santaló diagrams and other shape optimization problems (January 2021)
