My academic interests pertain to applying new technologies to improve the care of acutely ill and injured children, both here in New Haven and across the globe. To that end I have taught trainees from Africa and Asia, often with a portable ultrasound in-tow.


Education & Training

I am committed to a career in Health Services Research as a means to improve the care of children in the acute care setting. My short-term goal is to gain additional knowledge in health care management and policy and in assessing clinical and cost-effectiveness as well as efficiency of clinical interventions based on emerging technologies. My long-term career goal is to develop the expertise to design, to implement, and to evaluate the clinical and public health effectiveness of interventions that employ new emerging technologies for the acute care of children.

During the past several years I have focused on the application of new technology to improve the care of pediatric patients in the emergency department. Broadly speaking these projects have one or both of the following goals; 1) increase efficiency of medical care; and 2) enhancing the safety of the patients during the delivery of the medical care.

Most recently my efforts have focused on improving the health care of children in developing countries. To that end my projects have focused on

1. Improving the infrastructure and training for clinical research

2. Improving the medical education.

The two countries where I have devoted most of my time are Rwanda and China.

Recognition of pediatric sepsis in Rwandan hospitals.

Epdemiology of admissions to a newly-opened pediatric intensive care unit in Rwanda.

Developing a low-cost high flow nasal cannula system for resource-limited settings.

Developing a clinical research curriculum for faculty and trainees, Changsha, China.

Use of bedside ultrasound in resource-limited settings.

Pediatric curriculum development for University for Global Health Equity, a new medical school established by Partner in Health in Rwanda

Clinical Care


Lei Chen, MD, MHS, specializes in pediatric emergency medicine and treats children in the hospital suffering from trauma, seizures, asthma, abdominal pain and other conditions.

Dr. Chen is interested in adapting existing technologies to better care for children in developing countries. Calling the 2003 book, Mountains Beyond Mountains: The Quest of Dr. Paul Farmer, A Man Who Would Cure the World an inspiration, Dr. Chen is focused on “global health efforts to improve emergency and critical care of children in resource-limited settings.” He says, “I am currently mentoring a group of students to build a low-cost respirator for the developing world.”

Dr. Chen is an associate professor of pediatrics (emergency medicine) and of emergency medicine at Yale School of Medicine.
