I got a PhD in applied math not so long ago. I like inverse problems and optimization. I also drink a lot of coffe ☕

New paper out! We study a novel property ensuring linear convergente of Bregman Proximal Gradient Methods, and show the applicability of our results to KL regression problems, present for instance in Poisson inverse problems. 🖤 (With @esoubies.bsky.social, Christian Daniele, and Cédric Févotte)

A cover letter is that place in which you have to talk about yourself better than your mum does to her friends.

New paper out! Together with my postdoc advisors @esoubies.bsky.social and Cédric Févotte :) We study the optimization landscape of L0-Bregman relaxations, which naturally arise when one optimizes non-quadratic fidelity terms coupled with the L0-norm. 1/n

My first tweet is going to be rather philosophical: the amount of cultural inputs we receive just because of being in an academic environment is huge. And we should be thankful for that.

Se acabó. Fue un placer, un dolor, un orgullo. Y "La última" casi una catarsis, porque el odio y la mentira intoxican si pasas mucho tiempo cerca. Sirvió, claro que sirvió. No hay más que ver las reacciones histéricas que generaba. Gracias! elpais.com/opinion/2024... ✨ ❤️
