Hello! 👋

My name is Francisco Machado and I am a theoretical physicist working at the intersection of atomic physics and condensed matter.

Originally from Portugal, Physics has taken me through many places:

• 2022-present - ITAMP Fellow at the Harvard-Smithsonian Center for Astrophysics
• 2016-2022 - PhD in Physics at UC Berkeley (advised by Prof. Norman Yao)
• 2013-2016 - Bachelor of Science in Physics at MIT
• 2012-2013 - Physics program at University of Coimbra

See research for an overview of my research interests and the publications below (or arXiv) for a complete list of my publications.
