About me

I am a Research Scientist focusing on the development of algorithmic solutions for Artificial-Intelligence and Visual-Analytics. My algorithms and tools are used in several research groups and led to discoveries presented in important venues such as “Nature Communications”, “Nature Immunology” and the “Journal of Experimental Medicine”. I do not focus only on fundamental research, but also on the development of large, scalable and stable software and its path to useful products.

After my master, I worked for more than three years in an Italian start-up developing 3D scanners, now acquired by FARO, as research & development engineer and as research fellow at the University of Brescia. I received my PhD Cum Laude from Delft University of Technology in the Computer Graphics & Visualization group, in close collaboration with the Division of Image-Processing at Leiden University Medical Center. During the PhD I joined INRIA Saclay as Visiting Scientist, and I worked at Google AI with Alexander Mordvintsev, the creator of Google’s DeepDream. At Google, I published two research papers and developed an open source library released in the TensorFlow.js family. I currently work at Philips Research, with a joint appointment as Assistant Professor at Eindhoven University of Technology, focusing on the development of reliable and human-centered Artificial-Intelligence solutions for healthcare.
