Graduate medical education

The Donald and Barbara Zucker School of Medicine at Hofstra/Northwell offers a two-year clinical fellowship training program in pediatric surgery at Cohen Children’s Medical Center. Fellows are surrounded by faculty and staff committed to comprehensive care of children, from infants to young adults. Trainees learn to take responsibility for the preoperative, operative, and postoperative management of neonates and children with pediatric general surgery challenges and work with multiple subspecialty colleagues.

The Trauma Research Program focuses on the epidemiologic, clinical and behavioral study of childhood injury, injury prevention and trauma clinical care, with the ultimate goal of informing and guiding improved clinical practices. The group has multiple Institutional Review Board approved research study protocols and has published numerous peer-reviewed publications. We also participate in several national multi-institutional research trials.

The program currently leads or participates in a number of research initiatives, including:

  • Inflammatory response to injury
  • Car seat and vehicle safety
  • Clinical Practice Guideline development
  • Role of phlebotomy in solid organ injury
  • Team dynamics and communication
  • Pedestrian safety
  • Optimal resuscitation in pediatric trauma
  • Spinal Cord Injury Simulation-based team training/education
  • Trauma System development

Partnerships are fundamental to the program. Existing partnerships with the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell and the Feinstein Institutes for Medical Research enable our patients and community to benefit from our scientific advances in care.

The research team is dedicated to the education and development of new clinical scholars. We provide opportunities for research education to students, physician residents and interns from the Zucker School of Medicine. In addition, the team provides extensive educational support in the conduct of research to clinical staff at Cohen Children’s with the goal of improving clinical knowledge and best practice utilization.


Ping Wang, MD

Dr. Wang’s main research is focused on understanding the mechanisms responsible for cell and organ dysfunction after injury and sepsis, as well as their correction. More specifically, Dr. Wang is focused on the improvement of organ function after severe hypovolemia, or a state of decreased blood volume, and the role of sympathetic nervous system and parasympathetic nervous system in sepsis.

Ona Bloom, PhD

Dr. Bloom’s lab focuses on understanding biological responses to traumatic spinal cord injury. Her research addresses the urgent, unmet need to predict and promote functional recovery after traumatic spinal cord injury (SCI), a devastating injury affecting approximately 12,000 Americans annually. The long-term goal of the research conducted at the Bloom Lab is to identify cellular and molecular responses that promote successful functional recovery from SCI. 

Asha Varghese, PhD

Dr. Varghese earned her PhD in cellular and molecular biology. Over the past 20 years, she has been conducting research regarding signaling and acute inflammation relating to trauma, especially hemorrhagic shock and ischemia-reperfusion injury. Recently, her area of focus extended to neonatal sepsis research.

Jose M. Prince, MD

Dr. Prince is the director of the Laboratory of Pediatric Injury and Inflammation in The Feinstein Institutes' Center for Immunology and Inflammation. As a practicing pediatric surgeon, he focuses on translational research directed to understanding and regulating the injury response of children.

Francesca Bullaro, MD

Dr. Bullaro is a pediatric emergency physician and the associate trauma medical director of the trauma program. Her work focuses on the use of simulation to improve trauma care.
