Research Interests

The upcoming stage-IV Dark Energy surveys such as Euclid and LSST,  will observe the Universe with unprecedented accuracy, allowing us to investigate unsolved questions in current cosmology. All the methodologies and developments that have characterized my research so far work towards two big goals: making fast approximated simulations suitable for data analysis pipeline of upcoming cosmological surveys and investigating forward modeling techniques to exploit the potential of next-generation weak lensing data.  In parallel, I am working on data compression of weak lensing map summary statistics using deep convolution neural networks 

I am part of the Dark Energy Science Collaboration where I contribute studying higher order weak lensing statistics using differentiable simulations.

 I am one of the co-organisers of the Cosmostat Journal club. If you would like to give a talk and meet the CosmoStat group you can contact me or Tobias

I joined to a double degree program between the University of Naples Federico II and the Shanghai Normal University in 2019.
I graduated in March 2020 and obtained a MSc in Physics, majoring Astrophysics, at University of Naples Federico II. My Master thesis focused on the study of the Concentration-Mass relation of galaxy clusters in the next generation surveys.
From September to December 2019, I had a 3-month research experience as visiting student at Shanghai Normal University, where I developed part of my Master thesis.
