Alan Chiem, MD MPH

I started my position as Director of Emergency Ultrasound and Fellowship Director in 2012, after completing residency at Grady/Emory and my ultrasound fellowship at UC Irvine with Dr. Chris Fox. I am a Testamur of the National Board of Echocardiography, having passed the ASCeXAM (aka "echo boards") in 2015.  In addition, I completed a part-time clinical research fellowship with the UCLA Clinical Translation Science Institute (CTSI) in 2016.

My academic interests are in both undergraduate and graduate medical education, as well as the use of advanced echocardiography in the management of acute heart failure and critically ill patients. I love spreading the gospel of ultrasound, and I enjoy working with and being around others that have the same passion, whether they are EM-trained, IM/Cards/CC, Surgery or Radiology. I am fortunate to be at UCLA-Olive View, where there is a long tradition of excellence in residency training, collaboration between specialties, and the diverse pathology encountered in a public, safety net hospital.
