Inês Ochoa

I am an experimental particle physicist at LIP and I am based in Lisbon, Portugal. I am a member of the ATLAS experiment at CERN’s Large Hadron Collider.

Short Bio

In 2010, I completed my undergraduate studies in Physics at Universidade de Coimbra, where I am originally from. I moved to London in April 2011 to pursue a PhD at University College London. I moved to New York City in July of 2015 to work as a postdoctoral research associate at the Nevis Laboratories at Columbia University. In July 2020 I was awarded a La Caixa Junior Leader Postdoctoral Fellowship and joined LIP.
