Fellowship research

Extensive research opportunities are available in the Division of Cardiology. In-depth research opportunities are available in translational research and clinical research in areas of:

  • Nuclear cardiology
  • Echocardiography
  • Interventional cardiology
  • Electrophysiology
  • Heart failure research
  • Clinical epidemiology
  • Molecular cardiology

In the second and third years, residents can take advantage of two months of protected time for research. Abstract submissions and participation in regional and national meetings is highly encouraged. The expectation is for each Fellow to have at least three peer-reviewed manuscripts during the course of their fellowship.

Recent Presentations:

Our year fellows (left to right: Tushar Mishra, Irfan Shafi, Preeya Prakash, Neiberg Lima) at ACC22 in Washington, DC.

WSU/DMC fellows and residents taking a break from their many presentations to take a group picture at ACC22.
