Dr. Raul Chavez-Valdez is an assistant professor in the Department of Pediatrics with great interest in the mechanisms of delayed injury and repair/regeneration in the developing neonatal brain following injury, specifically following hypoxic-ischemic encephalopathy (birth asphyxia). He collaborates with Dr. Frances Northington (Pediatrics) and Dr. Lee Martin (Pathology/Neuroscience) in unveiling the importance of programmed necrosis in the setting of brain injury induced by birth asphyxia. He is especially interested in the role of brain derived neurotrophic factor and neurotrophin-4 following birth asphyxia and the changes that may explain the suspected excitatory/ inhibitory (E/I) imbalance particularly in the hippocampus. His work is highly translational since delayed hippocampal injury due to E/I imbalance may explain memory deficits observed despite therapeutic hypothermia in neonates suffering birth asphyxia. All of these aspects of developmental neuroplasticity are the base of his Career Development Award (NIH/NINDS-K08 award) and applications to other agencies. Additionally, he is part of multiple clinical efforts as part of the Neuroscience Intensive Care Nursery (NICN). He has been a Sutland-Pakula Endowed Fellow of Neonatal Research since September 2013.

Research in the Patrick Breysse Lab seeks to better understand the biological, chemical and physical factors that can impact a patient’s health. Our team is currently studying the effects of indoor and outdoor air pollution on childhood asthma, respiratory tract infections, chronic obstructive pulmonary disease (COPD) and other respiratory conditions. We also conduct research on secondhand smoke exposure around the world and have participated in a range of health and exposure studies in Peru, Nepal, Mongolia, Columbia and India.

The Jonathan Walsh Lab is currently researching longitudinal trends of diagnostic and procedural utilization in pediatric patients with head and neck complaints.

Research in the Jennifer Lee-Summers Lab explores cerebrovascular autoregulation, particularly during anesthesia. Our previous studies have examined cerebrovascular autoregulation and blood flow in patients with hypothermia, in neonatal patients with hypoxic-ischemic encephalopathy and in pediatric patients with moyamoya disease.

The Joanne Shay Lab primarily conducts research on pediatric pain management techniques. Our studies have explored pain management in special-needs children and patients, and we have studied non-traditional pain management methods, such as regional anesthesia and peripheral nerve blocks in children, medical acupuncture, and remote anesthesia services. We also have an ongoing interest in the business of medicine.

Work in the Courtney Robertson Lab is focused on identifying interventions that could minimize the neurological deficits that can persist after pediatric traumatic brain injury (TBI). One study used a preclinical model to examine potential disruption of mitochondrial function and alterations in cerebral metabolism. It was found that a substantial amount of mitochondrial dysfunction is present in the first six hours after TBI. In addition, we are using nuclear magnetic resonance spectroscopy to evaluate global and regional alterations in brain metabolism after TBI. We're also collaborating with researchers at the University of Pennsylvania to compare mitochondrial function after head injury in different clinically relevant models.

The Constance Monitto Lab conducts clinical research on pediatric pain management as well as basic science studies on chemotherapy resistance. In our pediatric pain management research, we work to assess the impact of low-dose opioid antagonism on opioid-related side effects, such as nausea and vomiting. We also analyze data on current methods of pediatric pain management in the United States. In addition, our team uses basic science studies to assess the success of epigenetic gene regulation on the development of resistance to chemotherapeutic agents in cancer.

Research in the Deborah Schwengel Lab focuses on perioperative care of pediatric patients with obstructive sleep apnea as well as anesthetic care for patients undergoing ethanol embolization of vascular malformations. Our team also explores topics within graduate medical education. In this field, our work has involved evaluating both an educational curriculum and a disaster preparedness curriculum for anesthesiology residents. We also have a long-standing interest in international adoption medicine.

Work in the Donald Shaffner Lab investigates several topics within critical care medicine. Our team conducts research on the mechanisms involved in neurologic injury from global ischemia as a result of cardiac arrest and resuscitation. We also study neurologic outcomes of pediatric patients who experience cardiac arrest.

Researchers in the Elizabeth Hunt Lab study innovative ways to improve the care quality and clinical outcomes of children who suffer cardiopulmonary arrest. Our work includes implementing rapid-response systems, capturing and analyzing cardiac-arrest data, and redesigning medical devices and simulators. We've introduced novel simulation approaches to education, including data-driven debriefing and the Rapid Cycle Deliberate Practice approach.
