Sergio Leos studies the shifting intellectual perspectives in the early-modern era, especially throughout the Iberian Atlantic world of the 16th and 17th centuries. His current research focuses on the ways Europeans interpreted and accommodated the unfamiliar realities of the New World. Other interests include the practice of ethnography and the effects of migration on individual and collective senses of identity. Prior to entering the Ph.D. program at Harvard, Sergio completed his B.A. in History with a certificate in Latin American Studies at Princeton University in 2017.
