About me
I am currently doing my postdoctoral research in IMPT project on improving parameterizations of gravity wave momentum fluxes in climate models, using statistical and machine learning methods, under supervision of Aurélie Fischer (LPSM - Université Paris Cité) and Riwal Plougonven (LMD/IPSL - École polytechnique).
I am from Cambodia. I did my Ph.D. in Applied Mathematics at UPMC - Sorbonne Université. I have also been working as a teaching assistant at UFR mathematics of Université Paris Cité (Paris 7) during my thesis.
Here are my Ph.D. Thesis and Slides.
Research interests
My Ph.D. research focuses on consensual aggregation techniques for combining a given number (small or large) of predictors in supervised machine learning problems. Moreover, I also explored the combination of supervised and unsupervised machine learning methods for prediction.
My postdoctoral research focuses on using ML methods to reconstruct balloon-observed gravity wave momentum fluxes from the large-scale flow variables of ERA5 dataset.
I am interested in the following topics:
- Combination of unsupervised and supervised machine learning methods, ensemble learning, clustering and aggregation methods.
- Deep learning, neural networks, artificial intelligence, online learning, big data…
