Friday Physics Forum
What is FPF? Faculty, post-docs, and students meet on a bi-weekly basis to discuss the physics of magnetic resonance imaging. This Friday afternoon discussion takes the form of a journal club, informal discussion, or presentation by a team member on a specific topic. We use this opportunity to build upon what we already know about MRI and to augment our understanding about new and emerging topics.
Who comes to FPF? All members of the UCLA community and our off-campus colleagues are welcome to join.
When and where is it held? Every other Wednesday afternoon on Zoom meetings.
