From July 27 to July 31, 2026, we successfully held the intensive PhD and Master’s course “Computational Imaging & Learning: From Physics to Data-Driven Methods” at Universidad de la República (UdelaR) in Montevideo, Uruguay.

The teaching team: Luca Calatroni, Christian Daniele, and Simone Sanna.

Course Overview

During this one-week school, we covered the mathematical foundations of physics-based inverse problems, forward modeling, and modern data-driven / hybrid reconstruction methods.

Each day combined theoretical morning lectures with hands-on afternoon practical labs using Python and PyTorch notebooks (ranging from CT reconstruction and Plug-and-Play methods to Deep Equilibrium Models).

• Dates: July 27–31, 2026
• Location: UdelaR, Facultad de Ingeniería — Montevideo, Uruguay
• Instructors: Luca Calatroni, Christian Daniele, and Simone Sanna

A big thank you to all the PhD candidates and Master’s students in Mathematics, Engineering, and Computer Science who participated and made the school such an engaging experience!

You can find the full syllabus and daily schedule on the dedicated Teaching page.

Sorry, but the page you were trying to view does not exist.

I am Christian Daniele, Chris for everyone. In this website you will find different resources about me and my work. I am a second-year PhD student at University of Genoa and Université Côte d’Azur since March 2025, supervised by Luca Calatroni, Samuel Vaiter and Silvia Villa.

About my research

My research focuses primarily on first-order optimization methods and inverse problems. In particular, I am working on hybrid frameworks for solving inverse problems, integrating neural networks with classical optimization algorithms to enhance reconstructive accuracy and computational efficiency.

About me

Before starting the PhD, I studied at University of Genoa, completing a Bachelor’s Degree in Mathematics and a Master’s Degree in Applied Mathematics. I have also been an intern at CNRS, Sophia Antipolis, France under the supervision of Luca Calatroni and Samuel Vaiter.

What else?

I love sports! In particular, beach volleyball, volleyball, tennis, and football. If you happen to meet me at a conference, don’t hesitate to invite me to play—whatever the sport, count me in!

Locations of key files/directories

• Basic config options: _config.yml
• Top navigation bar config: _data/navigation.yml
• Single pages: _pages/
• Collections of pages are .md or .html files in:
  • _publications/
  • _portfolio/
  • _projects/
  • _posts/
  • _teaching/
  • _talks/
• Footer: _includes/footer.html
• Static files (like PDFs): /files/
• Profile image (can set in _config.yml): images/profile.png

Tips and hints

• Name a file “.md” to have it render in markdown, name it “.html” to render in HTML.
• Go to the commit list (on your repo) to find the last version GitHub built with Jekyll.
  • Green check: successful build
  • Orange circle: building
  • Red X: error
  • No icon: not built
• Academic Pages uses Jekyll Kramdown, GitHub Flavored Markdown (GFM) parser, which is similar to the version of Markdown used on GitHub, but may have some minor differences.
  • Some of emoji supported on GitHub should be supposed via the Jemoji plugin .
  • The best list of the supported emoji can be found in the Emojis for Jekyll via Jemoji blog post.
• While GitHub Pages prevents server side code from running, client-side scripts are supported.
  • This means that Google Analytics is supported, and the wiki should contain the most up-to-date information on getting it working.

• Your CV can be written using either Markdown (preview) or generated via JSON (preview) and the layouts are slightly different. You can update the path to the one being used in _data/navigation.yml with the JSON formatted CV being hidden by default.

• The Liquid syntax guide is a useful guide for those that want to add functionality to the template or to become contributors to the template on GitHub.

MathJax

Support for MathJax (version 3.* via jsDelivr, documentation) is included in the template:

The default delimiters of $$...$$ and \\[...\\] are supported for displayed mathematics, while \\(...\\) should be used for in-line mathematics (ex., \(a^2 + b^2 = c^2\))

Note that since Academic Pages uses Markdown which cases some interference with MathJax and LaTeX for escaping characters and new lines, although some workarounds exist. In some cases, such as when you are including MathJax in a citation field for publications, it may be necessary to use \(...\) for inline delineation.

Mermaid diagrams

Academic Pages includes support for Mermaid diagrams (version 11.* via jsDelivr) and in addition to their tutorials and GitHub documentation the basic syntax is as follows:

    ```mermaid
    graph LR
    A-->B
    ```

Which produces the following plot with the default theme applied:

graph LR
A-->B

While a more advanced plot with the forest theme applied looks like the following:

---
config:
  theme: 'forest'
---
graph TD;
    A-->B;
    A-->C;
    B-->D;
    C-->D;

Plotly

Academic Pages includes support for Plotly diagrams via a hook in the Markdown code elements, although those that are comfortable with HTML and JavaScript can also access it via those routes.

In order to render a Plotly plot via Markdown the relevant plot data need to be added as follows:

    ```plotly
    {
      "data": [
        {
          "x": [1, 2, 3, 4],
          "y": [10, 15, 13, 17],
          "type": "scatter"
        },
        {
          "x": [1, 2, 3, 4],
          "y": [16, 5, 11, 9],
          "type": "scatter"
        }
      ]
    }
    ```

Important! Since the data is parsed as JSON all of the keys will need to be quoted for the plot to render. The use of a tool like JSONLint to check syntax is highly recommended.

Which produces the following:

{
  "data": [
    {
      "x": [1, 2, 3, 4],
      "y": [10, 15, 13, 17],
      "type": "scatter"
    },
    {
      "x": [1, 2, 3, 4],
      "y": [16, 5, 11, 9],
      "type": "scatter"
    }
  ]
}

Essentially what is taking place is that the Plotly attributes are being taken from the code block as JSON data, parsed, and passed to Plotly along with a theme that matches the current site theme (i.e., a light theme, or a dark theme). This allows all plots that can be described via the data attribute to rendered with some limitations for the theme of the plot.

which wil render as:
