Research statement
My main research interest is in statistics and machine learning; I am currently working on developing algorithms that employ resampling techniques to the problem of anomaly detection, and on the problem of expressing the expected statistical significance in an approximate way in searches for new signals.
I am a founding member, as well as member of the Steering Board, of the MODE Collaboration, where we aim at building a differentiable pipeline to do machine-learning informed optimization of detector and experiment design.
I am also a member of the CMS Collaboration, where I work as a statistics advisor (CMS Statistics Committee) and to experimental measurements in top-Higgs physics (ttH observation and top-Higgs coupling constraints in an EFT framework) and in Standard Model precision measurements (WZ, also constraining the triboson coupling in an EFT framework).

Machine-learning Optimized Design of Experiments
Luigi Favaro, Andrea Giammanco, Maxime Lagrange, Zahraa Zaher
We are among the founders of MODE (Machine-learning Optimized Design of Experiments, https://mode-collaboration.github.io/), a multi-disciplinary consortium of European and American physicists and computer scientists who target the use of differentiable programming in design optimization of detectors for particle physics applications, extending from fundamental research at accelerators, in space, and in nuclear physics and neutrino facilities, to industrial applications employing the technology of radiation detection.
We also participate to the very closely related activities of the "Codesign" work package in the EUCAIF network.
We aim to develop a modular, customizable, and scalable, fully differentiable pipeline for the end-to-end optimization of articulated objective functions that model in full the true goals of experimental particle physics endeavours, to ensure optimal detector performance, analysis potential, and cost-effectiveness.
The main goal of our activities is to develop an architecture that can be adapted to the above use cases but will also be customizable to any other experimental endeavour employing particle detection at its core. We welcome suggestions, as well as interest in joining our effort, by researchers focusing on use cases for which this technology can be of benefit.

Properties of ttW and ttH production
Anna Benecke, Andrea Giammanco, Oguz Guzel, Zak Lawrence, Jindrich Lidrych
We take advantage of the large statistics already recorded in Run 2 and being recorded in Run 3 by the CMS experiment to launch a systematic study of cross section, angular asymmetries and other properties in the ttW and ttH processes, which have a potentially large sensitivity to non-SM effects.
In synergy with the CP3 phenomenology group, we aim at reporting our results in a form that can be easily translated in EFT constraints.
