About me

I am a PhD student of the ELLIS PhD & PostDoc program at the Institut de Robòtica i Informàtica Industrial (IRI), where I am supervised by Prof. Carme Torras and Dr. Adrià Colomé. During 2024, I visited the École Polytechnique Fédérale de Lausanne (EPFL), where I was hosted by Prof. Amir Zamir .

Previously, I interned at Amazon, where I worked on computer vision and the learning-to-rank problem, and at Logitech, where I worked on voice conversion. I hold a Master's degree in Data Science from EPFL and a Bachelor's Degree in Telecommunications Technologies and Services Engineering from UPC.
