I’m interested in problems of mathematical physics in connection with stochastic analysis. More generally in the description and analysis of random influences in evolutionary systems inspired by physics. In recent years I’ve been working in developing Rough Path Theory, which is a set of ideas and tools which allows a detailed analysis of irregular signals on nonlinear systems. I’ve generalised the original theory, introduced by T. Lyons, to a wider class of signals, Branched Rough Paths and proposed various other theories in order to handle more complex dynamics like those underlying parabolic and hyperbolic PDEs. Rough paths and their generalisations have inspired the theory of Regularity Structures, invented by Hairer to describe the local structure of solutions to singular PDEs of the kind appearing in mathematical physics: the Stochastic Quantisation Equation, the Kardar—Parisi—Zhang equation, the parabolic Anderson model. In a parallel development, in collaboration with Imkeller and Perkowski, I introduced tools of harmonic analysis also applicable to such singular SPDEs. In collaboration with Flandoli and Priola and subsequently with some PhD students we analysed the effect of random perturbation in nonlinear infinite dimensional dynamics modelled by PDEs and we showed some situations where the presence of the noise improves the behaviour of solutions for hyperbolic and dispersive PDEs.

 Research Area G My main research interest is the study of partial differential equations in presence of noise.
In collaboration with P. Imkeller and N. Perkowski we developed [1] a new method to define and analyze stochastic partial differential equation with quite singular nonlinearities like the KardarParisiZhang equation, the cubic reactiondiffusion model in three dimension with additive white noise and the parabolic Anderson model in two and three dimensions, among others. In the context of the KPZ equation together with N. Perkowski we proved [2] uniqueness of energy solutions [3] for the KPZ equation. Energy solutions is a flexible tool to prove universality of fluctuations in weakly asymmetric particle systems (see e.g. [4]).
Another line of research concerns the regularizing effects of the noise in the dynamics of partial differential equations. Together with F. Flandoli and E. Priola we gave one of the first examples of regularization by noise in the context of stochastic partial differential equations [5]. In collaboration with my former Ph.D. student Khalil Chouk [6] we proved regularization by stochastic modulation in nonlinear Schrödinger equations.  Research Area C I studied path integral techniques in the analysis of certain quantum systems.
In particular, in collaboration with F. Hiroshima and J. Lörinczi [7] we explicitly constructed a measure on path space for the ground state of the renormalized Nelson Hamiltonian. This Hamiltonian describes the interaction of a Boson field with a quantum nonrelativistic particle. With J. Lörinczi [8] we constructed path integral representations for the interaction of particles with bosonic vector quantum fields, making a link with the theory of stochastic currents and rough paths.
With H. Koch and T. Oh we started the investigation of singular stochastic hyperbolic PDEs [9] which can be seen as simple models mimicking the behavior of the renormalization for quantum fields in Minkowski space or as large scale descriptions of fluctuations for nonlinear waves.
