Work Experience

Researcher and Data Scientist

2019 - PRESENT
Bruno Kessler Foundation
  • Developed a digital contact tracing simulator combining a mathematical forecast model with a spread simulation on a real network. The technology has been used in the creation of the work-safety startup, Tech4Safe.
  • Designed and developed an open-source tutorial on PyTorch Geometric, a leading tool for implementing geometric deep learning algorithms. The video tutorials—available at https://github.com/AntonioLonga/PytorchGeometricTutorial—have 50,000 views.
  • Built and executed a federated learning model for a secure training of a distributed anomaly detection system.
Technologies: Deep Learning, Machine Learning, Graphs, Applied Mathematics, Numerical Simulations, Data Science, Scientific Data Analysis, Mathematics, Research

Researcher

2015 - 2019
University of Stuttgart
  • Developed a benchmark to test uncertainty quantification methods for the reliable simulation of geophysical problems. The benchmark has been developed as the result of the collaboration between four research groups across multiple disciplines.
  • Implemented a package for the training of greedy algorithms for kernel-based learning available at https://github.com/GabrieleSantin/VKOGA. The algorithms have been used in several research projects.
  • Designed, analyzed, and implemented a machine learning surrogate to accelerate the flow simulation in a model of the human vascular network. The model achieved a 0.1% relative error of order and a one-million speedup factor over the full system.

Federated Anomaly Detection

A federated learning model to train an anomaly detection classifier using distributed and private datasets. The training is designed to permit the collaboration of different agents that share insights to improve their own classifiers while never sharing data.

Digital Contact Tracing

https://github.com/DigitalContactTracing/covid_code
A Python simulator of a digital contact tracing system that combines a mathematical model's numerical simulation with an agent-based spread model on a real contact network. The system allows the user to design, tune, and test intervention scenarios to contain the spread of a virus under several constraints.
