Present Position and PostDoc mentor:

• 2024-Present: Postdoc in applied mathematics, Chalmers University of  Technology, Göteborg, Sweden.
  I'm a postdoc in the applied mathematics unit, under the guidance of Prof. Annika Lang. We work on SPDE on manifolds but on a theoretical and computational level, with the goal of finding application to real life problems such as cell evolution and ice crystal formation.

Work Activities

• Teaching:

1. Teaching Assistant - Advance Statistics (Course) - Pisa University, Pisa, 2019.
   Multivariate statistics, classification and clustering, time series analysis. From a theoretical point of view and through the implementation via a statistical software.

2. Teaching co-Orginizer - Stochastic Partial Differential Equations (Course) - Chalmers University, Gothenburg, Sweden, 2025.
   Stochastic partial differential equations (SPDE) are considered in the sense of Itô. We extend the theory of It̂ stochastic differential equations to infinite dimensions by considering SPDE in the framework of Hilbert spaces. Mild solutions are then simulated which requires approximation in space, time, and of the infinite-dimensional driving Wiener noise. We prove strong and weak convergence rates of the considered approximation schemes. 

• Invited talks and lectures:

1. Probability Lecture Series (Lectures series) - Scuola Normale Superiore, Pisa, 2023.
   Particle Aggregation Under Turbulent Flows
   Abstract: Smoluchowski model is introduced from a stochastic particle system. A gas-kinetic theory on coagulation is recovered. Insight on mass displacement due to turbulence is shown numerically. Based on joint works with Franco Flandoli and Ruojun Huang.

2. China - Hong Kong - Sweden: frontiers of stochastic computations (Series of invited talks) - CAS, Beijing & CSU, Changsha & PolyU, Hong Kong, 2025.
   Stochastic Heat Equation driven by Levy noise on the Sphere
   Abstract: In these three talks, given at CAS, CSU and PolyU in the invited two weeks workshop, different aspects of the SHE with Levy noise on the sphere are discussed. From numerical implementation, regularity of the solution, weak and strong convergence rate both for spectral and fully discrete schemes.

• Organizer:

1. TuBA Workshop (Organizer) - Scuola Normale Superiore, Pisa, 31/01/2024+3/02/2024.
   The objective of the Turbulence on the Banks of the Arno (TuBA) workshop is to provide a platform for early-stage researchers (ideally Ph.D. students and postdoctoral fellows) working in the field of turbulence to come together, exchange ideas, and present their own research.

2. Surfaces and Randomness: summer school (Organizer) - Chalmers University of Technology & University of Göteborg, Göteborg, Summer 2026.
   The objective of the Surfaces and Randomness transformation (SuRTr) summer school is to provide a platform for researchers working in the field of theoretical and numerical study of PDE and SPDE and manifold and the construction of random evolution on surfaces.

   Averaged Dissipation of Transport Noise with Levy integral
   Abstract: In one spatial and arbitrary jump dimension, the averaged solution of a Marcustype SPDE with pure jump Lévy transport noise satisfies a dissipative deterministic equation involving a fractional Laplace-type operator. We present numerical simulations showing that dissipation occurs for the averaged solution, with a behavior like a fractional Laplacian.

   Approximation of the Lévy-driven stochastic heat equation on the sphere 

Abstract: The stochastic heat equation on the sphere driven by additive Lévy random field is approximated by a spectral method in space and forward and backward Euler-Maruyama schemes in time, in analogy to the Wiener case. New regularity results, strong and weak convergence rate are proven. Numerical simulations confirm the theoretical results.
