TOMMASO DORIGO, Ph. D.
First Researcher @ INFN
I am an experimental particle physicist working as a First Researcher for the Italian institute for nuclear physics (INFN), and a member of the CMS experiment at CERN since 2001; previously (1995-2012) I have been a member of the CDF experiment at Fermilab.
I am married since 2017 with Kalliopi Petrou, a lyrical soprano singer, and have a son (Filippo, 22) and a daughter (Ilaria, 18) from a previous marriage. I live in Padova, where I work for the INFN as well as for the University of Padova (as a hired professor).
My research interests are extended in three partly synergic directions:
- in Particle Physics, where they span from Higgs boson physics to top quark physics, to searches for new phenomena extending
our current knowledge of subnuclear world;
- in Statistics, focusing on parameter estimation, frequentist methods, handling nuisance parameters in statistical inference, and multivariate analysis;
- in Computer Science, targeting machine end-to-end optimization of physics measurements with machine learning, on differentiable programming, and on anomaly detection and unsupervised techniques.

For the CMS experiment
(2001-present) I have focused my research activities on Higgs physics and on searches for new phenomena, as well as on the development of advanced analysis tools for the calibration of the muon momentum scale (MuScleFit
), used in Higgs discovery analyses, the modeling of QCD backgrounds in multi-jet final states (Hemisphere mixing
), the investigation of multi-dimensional parameter space of new physics theories with unsupervised tools, and the anomaly detection approach to searches of new phenomena (Inverse Bagging
Previously, for the CDF experiment
(1995-2012) I have contributed to the top quark search and discovery
and to the construction of the muon system upgrade of the CDF-II detector. I have produced the first observation of Z->bb decays in hadron collisions
, and developed a trigger for the calibration of b-quark jets using Z->bb decays.
Statistics and Machine Learning
STATISTICS AND MACHINE LEARNING
As a member (Sep 2009-present) and chair
(Jan 2012-Jul 2015) of the CMS Statistics Committee I have been ensuring the highest standards of statistical inference in data analysis for the publications of my experiment, advising the collaboration on best practice and performing the screening of ALL journal publications from the point of view of statistics technique and description.
Through the design and implementation of the AMVA4NewPhysics ITN project (see below
) I have brought Statisticians and Physicists together with the purpose of enabling a common language and addressing specific problems of HEP data analysis. I am fostering the interest of Statistics students in Padova toward HEP applications and studies, by offering theses and teaching particle physics at the Masters in Statistical Sciences.

as well as in the design of new techniques customized to the very special use cases provided by HEP and related research. These activities are in part the result of collaboration with the darkmachines
and the GradHep
collaborations, to which I belong, as well as the ETN networks AMVA4NewPhysics
