Stefano Tognini is a Research Scientist at the Computational Sciences and Engineering Division as a member of the Scalable Algorithms and Coupled Physics Group.

Before joining ORNL, he received his Ph.D. in Physics from Federal University of Goias after working at Fermilab and ANL on two High Energy Physics experiments, namely MINOS and NOvA. These are decade long, worldwide endeavors to answer questions on neutrino physics, astrophysics, dark matter, and more, which provided him opportunities to work with different teams on a wide set of tasks and topics, including testing detector electronics, maintaining detector operation centers, developing Monte Carlo, and performing data analyses.

At ORNL, his main efforts are now focused on Celeritas, a GPU Monte Carlo particle transport code for High Energy Physics experiments. This project is a multi-laboratory collaboration encompassing ORNL, Fermilab, ANL, and LBNL.
