Fabian Crespo is a biological anthropologist specialized in human immunology. His main research goal is the study of the immune system, and how different forces (especially infectious diseases) have shaped the inflammatory responses and the overall immune competence in different human populations. He explores how different past epidemics and pandemics reshaped immunological and biosocial landscapes in human populations. His general approach to study the heterogeneous immunological landscapes observed in past populations involves a multidisciplinary approach combining experimental immunology, bioarchaeology, and history. His current projects are studying how chronic infections such as tuberculosis, leprosy, and syphilis reshape systemic inflammation; and how different skeletal inflammatory lesions/alterations can be used to reconstruct skeletal inflammatory phenotypes. All projects involve collaborations with different researchers from national and international institutions. Locally, he is currently working with colleagues from University of South Carolina; Ohio State University; Mississippi State University; George Mason University; and University of Georgia; and internationally with colleagues from Durham University (England); National Institute of Anthropology (Argentina); and University of Buenos Aires (Argentina).
