My clinical passion is in the care of children in resource-limited, particularly tropical, settings. As such, my primary interests within Emergency Medicine are diarrhea, respiratory distress, sepsis, shock, and trauma. I am also very interested in the application of bedside ultrasound to patient care, both in resource-rich and underserved settings. Within Infectious Diseases, my primary interests are in fevers of unknown origin, HIV/AIDS, malaria, neglected tropical diseases, parasitic infections, travel medicine, and tuberculosis.
My overall career goal is to contribute to a substantive improvement in childhood morbidity and mortality on a global level. To address this, my major research interests are in the development of a better understanding of the pathophysiology underlying chronic and acute childhood malnutrition, improving the diagnosis and treatment of malnourished children, and improvements in the diagnosis and management of tropical infectious diseases. The majority of my experience in these domains has come in the conduct of large clinical trials in rural Malawi as well as in smaller hospital-based cohort studies to complement my clinical experience caring for children and adults in austere settings around the world.
After several years in a purely academic position, as of January 2017 I have moved abroad full-time to become more engaged in direct patient care in the tropics, educate local health care workers, conduct field research, and to help strength local health systems. I maintain a part-time academic appointment at Washington University in St. Louis in order to improve patient care, research, and education in global health.
