Research interests

I work on the mathematical modeling of interesting problems belonging to the fields of image processing, artificial intelligence, and the analysis of digital data. My preferred tools for this purpose are techniques based on the calculus of variations, partial differential equations and optimization. Lately, I have put some effort on using these methods on the mathematical modeling and understanding of convolutional neural networks to tackle challenging problems from Health sciences.

Some keywords that somehow may describe my interests are:

  • Variational methods; Nonlinear PDE's; Ill-posed inverse problems.
  • Numerical methods and optimization; Multigrid methods.
  • Convolutional neural networks, image processing and data analysis.
  • C/C++, Python and Matlab programming.
