Projects
Comprehensive uncertainties for generative models
Develop a method to include uncertainties, starting from Bayesian generative networks; expand strategies to model systematic uncertainties using conditional training on nuisance parameters; extend NNPDF methodology for architecture-driven and parameter-driven uncertainties to generative models; study the effect of guided implicit bias on amplification factors between training and generated sample size.
Automated General Searches for New Physics
In contemporary high-energy physics, the number of potential scenarios for physics beyond the Standard Model far exceeds the capacity of dedicated searches. This disparity stresses the need for model-agnostic approaches that explore a broad spectrum of possibilities within the theoretical signal landscape.
