Return to Tulane Doctors


Dr. Schieffelin received his medical degree from Tulane University School of Medicine in 2001. He continued his training (2001-2005) in a combined Internal Medicine and Pediatrics Residency at Tulane University.  Dr. Schieffelin went on to complete a combined fellowship training program in Adult and Pediatric Infectious Diseases at Louisiana State University Health Sciences Center in New Orleans and Tulane University (2005-2009).  In 2009, Dr. Schieffelin joined the Tulane University School of Medicine faculty in the Departments of Medicine & Pediatrics and is currently an Associate Professor of Pediatrics and an Adjunct Associate Professor in the Department of Medicine.

Dr. Schieffelin devotes a significant amount of time to the laboratory. His research focuses on the natural history, clinical care and immunology of viral hemorrhagic fevers (VHFs). Currently he is involved in both basic science and clinical research on Flaviviruses, such as dengue and Zika, as well as  Lassa fever virus and Ebola virus. His laboratory studies how antibody-virus interactions can have both protective and pathogenic effects. He is also involved in several clinical, translations and epidemiological studies of SARS-CoV-2.

As a faculty member, he has been Principal Investigator and Co-Investigator on several NIH-funded grants and contract investigating Lassa fever. This research has laid the groundwork for the proposed work by developing necessary clinical and laboratory infrastructure and data collection tools. In addition, it established strong ties with the staff of the Sierra Leone National Lassa Fever Program. He has successfully administered the projects (e.g. staffing, human subjects protections, budget), collaborated with a diversity of other stakeholders, and produced several peer-reviewed publication and several more in preparation.  During the Ebola Outbreak, he served as a consultant to the WHO Global Outbreak Alert and Response Network in Sierra Leone participaing in both clinical care and local staff training.  He continues to follow a cohort of Lassa Fever and Ebola Virus Disease survivors and their household contacts in Sierra Leone.  The long-term goal of his research program is to develop and test new supportive care and therapeutic strategies for VHFs.
