Dr. Kaitlyn Sadtler is a scientist and chief of the Section on Immunoengineering at the National Institute of Biomedical Imaging and Bioengineering (NIBIB), focusing on the immune response to traumatic soft tissue injury and subsequent reconstruction.
She began her lab at NIBIB after a postdoctoral fellowship at the Massachusetts Institute of Technology (MIT) in the Department of Chemical Engineering, working on the molecular mechanisms of immune activation in the foreign body response. She completed her Ph.D. at the Johns Hopkins University School of Medicine, where her research showed a role for immune cells in biomaterial-mediated muscle regeneration.
Dr. Sadtler has led research that has been published in journals such as Science, Nature Communications, Nature Materials, and Science Translational Medicine. She was recognized as a TED Fellow and delivered a TED talk that was listed as one of the top-viewed talks of 2018. She was selected for the Forbes 30 Under 30 Science List, the MIT Technology Review’s 35 Innovators Under 35, the World Economic Forum’s Young Global Leaders, the TIME100 Next List, and the National Academies of Science Engineering and Medicine’s New Voices Program. She also received the 2021 Outstanding Recent Graduate Award from Johns Hopkins University and an honorary doctorate from her undergraduate institution, the University of Maryland, Baltimore County (UMBC).
At NIH, Dr. Sadtler lent her lab’s expertise to the fight against COVID-19, leading a study that detected 16.8 million undiagnosed SARS-CoV-2 infections in the United States after the first pandemic wave in the country. She continues her work on immunoengineering in the context of traumatic injury, focusing on the balance of tolerance and autoimmunity during tissue reconstruction. In 2023, her group published a study implicating a new immune cell type in self-tolerance after volumetric muscle loss.
