During his time at University of Pennsylvania, Dr. Teran led the resuscitative transesophageal echocardiography (TEE) program, implemented a multi-center TEE registry, and became a testamur of the National Board of Echocardiography Critical Care Echocardiography Examination.

Dr. Teran's translational research focuses on the study of strategies to improve outcomes in cardiac arrest resuscitation, including the use of critical care ultrasound and TEE. His work has been published in high-impact journals including JACC, JAHA, JASE and Resuscitation, and has received grant funding from the Emergency Medicine Foundation (EMF) and the Zoll Foundation.

As a leading expert in the emerging use of TEE across emergency and critical care environments, Dr. Teran has given over 80 presentations nationally and internationally and has directed training workshops for the Society of Academic Emergency Medicine (SAEM), the Emergency Medicine Resident's Association (EMRA), and the World Interactive Network Focused On Critical UltraSound (WINFOCUS). He is a founder faculty member of the Resuscitative TEE Project, Co-Chair of the Resuscitative TEE Collaborative Registry, and course director of The Resuscitative TEE Workshop, an international course that has trained over 1,000 clinicians on the use of critical care TEE globally.
