Biography

I am a PhD student since September 2021 under the supervision of Laurent Massoulié, working on the theory and algorithms of Machine Learning. I am particularly interested in optimization (in all its form: distributed, decentralized, stochastic,…), topics related to Federated Learning, gossip algorithms and high-dimensional statistics.
