Dragulescu has successfully managed many projects, collaborated with other researchers and published numerous peer-reviewed manuscripts from each project, many of which were published in the Journal of the American Society of Echocardiography. Her research is centered on introducing and validating new echocardiographic techniques in paediatric cardiology, with a focus on techniques to assess ventricular function and complex anatomy using three-dimensional imaging. Her publications are internationally recognized and this is reflected in multiple speaker invitations to different national and international echocardiography meetings and teaching courses.
