The Echocardiography Core Laboratory has an immediate opening for a postdoctoral research fellow. The Individual will train in the research program of Dr. Jae K. Oh and other Core Lab staff at Mayo Clinic. The Echocardiography (Echo) Core Lab is a core laboratory of the Cardiovascular Research Center. The Echo Core Lab offers third-party interpretation of echocardiographic studies for clinical trials around the world, partnering as a research collaborator with trial investigators and industry sponsors. In particular, the Echo Core Lab provides echocardiography measurements for clinical investigations and trials that use echocardiography for patient eligibility or study endpoints or both. Utilizing Mayo Clinic's wealth of experience and standing as the nation's foremost institution for cardiovascular diseases and echocardiography, Mayo Clinic cardiologists provide rapid, reliable and reproducible readings with unparalleled quality assurance. • Rapid - A staff of dozens of physicians and sonographers allows the Echo Core Lab to provide a timely turnaround for even the largest trials. The Echo Core Lab can accommodate clinical trials ranging in size from hundreds of studies to several thousand studies with speed and precision. • Reliable - Mayo Clinic is the premier center for echocardiography in the world, performing upward of 250 examinations a day. Since its inception in 1999, the Echo Core Lab has published more than 1,000 papers on the subject of echocardiography. Many Echo Core Lab faculty and staff have participated in writing echocardiography guidelines. The Echo Core Lab holds regular quality assurance meetings to standardize echocardiography measurements and interpretation. • Reproducible - Clinical trials that use echocardiography require the highest caliber of objective interpretation for optimal results — results that can be reproduced and confirmed by investigators and the scientific community. Mayo Clinic's stringent quality control procedures provide a database of precise readings on which to base research conclusions. Preferred experience includes expertise in echocardiographic imaging and interpretation.
