Meet the Team
Dr. Jared T. Marx, MD, AEMUS-FPD
Dr. Jared Marx is a Professor of Emergency Medicine at the University of Nebraska Medical Center (UNMC) and Chief of the Division of Emergency Ultrasound. He has spent more than 15 years building POCUS programs, training physicians, and advancing point-of-care ultrasound education.
​
After completing his Emergency Medicine residency at UNMC, Dr. Marx pursued fellowship training in Emergency Ultrasound at Palmetto Health. He then joined the faculty at the University of Kansas Medical Center (KUMC), where he developed the Emergency Medicine residency ultrasound program and established an Emergency Ultrasound Fellowship.
​
Dr. Marx later returned to UNMC with the goal of rebuilding its Emergency Department POCUS program. What began with minimal clinical POCUS utilization has grown into a program performing more than 4,000 clinical POCUS examinations annually. He established UNMC's Advanced Emergency Medicine Ultrasonography (AEMUS) Fellowship and pursued accreditation as soon as the national accreditation pathway became available. He subsequently obtained AEMUS Focused Practice Designation (FPD) through the American Board of Emergency Medicine.
​
In 2026, Emergency Ultrasound became a formal division within the Department of Emergency Medicine, with Dr. Marx serving as Division Chief and leading a team that includes three additional fellowship-trained ultrasound faculty.
​
Dr. Marx was promoted to Professor of Emergency Medicine in 2021 and awarded tenure in 2026.
​
His educational philosophy is the foundation of POCUS Geek: make ultrasound understandable, keep examinations focused on the clinical question, recognize the findings that matter, and use that information to make better decisions at the bedside.
