EMERGE: Enabling Medical Research Growth in Emergency Medicine


2013 - 2015

Mucio Kit Delgado, MD, MS

Dr. Delgado is an Instructor in the Department of Emergency Medicine and a Faculty Fellow in the Center for Epidemiology and Biostatistics at the University of Pennsylvania.  He was previously an Instructor in the Division of Emergency Medicine, Department of Surgery at Stanford University, as well as Affiliated Faculty in the Center for Primary Care and Outcomes Research at Stanford where he completed a fellowship and Masters of Science in health services research.  Dr. Delgado’s goal is to become an independent clinician-investigator in patient-oriented health services research with a focus on improving emergency care outcomes.  He will be working with robust mentoring team at University of Pennsylvania to develop expertise in: 1) identifying ways to improve the detection and resuscitation of traumatic hemorrhagic shock in the prehospital and emergency department setting; and 2) identifying geographic disparities in traumatic shock outcomes in order to design population and systems level approaches to improve outcomes.  He will also continue previous work to identify emergency department patients at highest risk for clinical decompensation and adverse outcomes if not admitted to intensive care.  In this work, he will focus on non-ventilated patients with dyspnea due to pneumonia or chronic obstructive pulmonary disease as well as patients with sepsis without shock since his previous research demonstrated that these patients are the most likely to be transferred to intensive care shortly after admission to the hospital ward from the emergency department.

Dan Holena MD

Dr. Holena completed his undergraduate work at McGill University in 1996. He then went on to obtain his MD from SUNY Stony Brook School of Medicine in 2002. He then completed his General Surgery residency at the Weill-Cornell New York Presbyterian Hospital program in 2007, followed by a Trauma and Surgical Critical Care fellowship at the University of Pennsylvania. Since 2009, he has been Assistant Professor in Surgery, Division of Traumatology, Surgical Critical Care, and Emergency Surgery at the University of Pennsylvania Perelman School of Medicine.

Dr. Holena’s current research interests involve time-sensitive surgical disease states and the development of posttraumatic organ failure. He is currently working with multidisciplinary teams examining the distribution of trauma care systems throughout the US. Using trauma as a model, he hopes to work toward the development of a similar system of care for emergent and urgent surgical conditions. Dr. Holena has additional interest in the association between baseline anthropomorphic metrics and the development of post-traumatic organ failure, and hopes to examine the relationship between central sarcopenia and the development of acute lung injury.

Tiffani Johnson, MD

Dr. Johnson graduated from Trenton Central High School at the age of 16, and completed her undergraduate education at Xavier University of Louisiana at age 19. She received her Medical Degree from UMDNJ-Robert Wood Johnson Medical School in 2006, followed by Pediatric Residency in the Community Health Track at Children's National Medical Center. After spending one year working for the Emergency Medical Services for Children National Resource Center, she completed her Pediatric Emergency Medicine Fellowship at the Children's Hospital of Pittsburgh. Her clinical fellowship was combined with a T32 research training program at the University of Pittsburgh. Dr. Johnson came to Penn in July 2013 as an Attending Physician in the Division of Emergency Medicine at the Children's Hospital of Philadelphia, Instructor in Pediatrics at the University of Pennsylvania Perlman School of Medicine, and EMERGE K12 Scholar.

Dr. Johnson's long-term research goal is to address racial/ethnic disparities in pediatric emergency care through three sequential phases of research that involves 1) identifying, 2) exploring the root causes of, and 3) reducing disparities. Her current research projects seek to determine patient-, parent-, provider-, and system-level factors that contribute to racial/ethnic disparities in the emergency department management and clinical outcomes of injured children. This research is being conducted with a multi-disciplinary team with content expertise in the areas of racial/ethnic healthcare disparities, epidemiology, biostatistics, and injury research. She hopes to generate new insight into the underlying sources of disparities that she will use to develop interventions to improve the equity of care for pediatric injuries and other conditions.
