Sabrina Marie Asturias Simons is the Chief of Trauma and Emergency Surgery at Roosevelt Hospital, the busiest trauma center in Guatemala and an NIH-funded investigator in trauma systems. She completed her medical and surgical training in Guatemala, including a Masters in Medical Science, before completing a fellowship in trauma surgery at the Los Angeles County Trauma Center 2015. She has extensive experience in managing transnational collaborations in injury and prevention. As a Co-Principal Investigator on a NIH Fogarty Institute grant, she developed Guatemala’s first trauma registry. Through an NIH R25 mechanism, she used information and communication technologies to further advance Guatemala's capacity for trauma information systems.  She now leads the CrashSavers Hemorrhage Control team that spans Guatemala, Chile, and the United States. Every day, she operates on patients in severe hemorrhagic shock after trauma. She is grateful to the Global Surgical Training Challenge for funding her team to develop an intervention that will directly improve these patients’ chances of survival.
