My focus is on how people live different aspects of their daily lives in Brazil’s present and past. My recent projects analyze how patients, health care professionals, and policy makers interact with each other and the built environment. I am particularly interested in how people live and work within rigid social and material structures that often misattribute the relationship between cause (culture) and effect (disease), leading to enduring health issues. Many of my previous projects examined the constructions of identities, especially how ethnic groups like Asian-Brazilians, Arab-Brazilians, and Jewish-Brazilians understand their own and national spaces. My research is important to my teaching, and many of my classes include oral and digital history projects. See, for example, Pauliceia 2.0, Windows into English Avenue and Vine City, and Nikkei Identity in Oizumi, Japan.
Books

My most recent book is Living and Dying in São Paulo: Immigrants, Health, and the Built Environment in Brazil (Duke University Press, 2025/Viver e morrer em São Paulo: Imigração, saúde e infraestrutura urbana (século XIX até o presente) (São Paulo: Editora UNESP, 2025). The book stresses how the state and residents engage with everyday health practices, health spaces, and health imaginaries and highlights material, political, and social residues, persistent structures of repetition. Material residues that structure well-being are and were omnipresent as textile workshops discard piles of strips of cloth on the streets where they collect water and become mosquito breeding grounds. The residues of clogged and overflowing sewers do the same. Identifying and studying health residues demands the diverse approaches, sources, and methods that generated the data for Living and Dying In São Paulo. Residues thus both create and are created in the daily lives of people during their cycles of health crises, visits with medical professionals, and in their quotidian discussions of everything from gun violence to human and non-human animal borne diseases.

Immigration, Ethnicity and National Identity in Brazil (Cambridge University Press, 2013; Editora UNESP, 2015) examines the immigration to Brazil of millions of Europeans, Asians, and Middle Easterners from the nineteenth century to the present.
I am interested in how these newcomers and their descendants adapted to their new country and how national identity changed as they became Brazilians along with their children and grandchildren. I argue that immigration cannot be divorced from broader patterns of Brazilian race relations, as most immigrants settled in the decades surrounding the final abolition of slavery in 1888 and their experiences were deeply conditioned by ideas of race and ethnicity formed long before their arrival.

I am also the author of A Discontented Diaspora: Japanese-Brazilians and the Meanings of Ethnic Militancy (Duke University Press, 2007; Editora Paz e Terra, 2008). This book investigates broad questions of ethnicity, the nature of diasporic identity, and Brazilian culture. I do this by exploring particular experiences of young Japanese Brazilians who came of age in São Paulo during the 1960s and 1970s, an intensely authoritarian period of military rule. The most populous city in Brazil, São Paulo was also the world’s largest “Japanese” city outside of Japan by 1960. Believing that their own regional identity should be the national one, residents of São Paulo constantly discussed the relationship between Brazilianness and Japaneseness. As second-generation Nikkei(Brazilians of Japanese descent) moved from the agricultural countryside of their immigrant parents into various urban professions, they became the “best Brazilians” in terms of their ability to modernize the country and the “worst Brazilians” because they were believed to be the least likely to fulfill the cultural dream of whitening. My research analyzes how Nikkeiboth resisted and conformed to others’ perceptions of their identity as they struggled to define and claim their own ethnicity within São Paulo during the military dictatorship.
For this project I used a wide range of sources, including films, oral histories, wanted posters, advertisements, newspapers, photographs, police reports, government records, and diplomatic correspondence. I focus on two cultural arenas—erotic cinema and political militancy—to highlight the ways that Japanese Brazilians imagined themselves to be Brazilian. Young Nikkeiwere sure that their participation in these two realms would be recognized for its Brazilianness, but they were mistaken. Whether joining banned political movements, training as guerrilla fighters, or acting in erotic films, my research subjects militantly asserted their Brazilianness only to find that doing so reinforced their minority status.
A Discontented Diaspora: Japanese-Brazilians and the Meanings of Ethnic Militancy was awarded the 2010 Roberto Reis Prize (Honorable Mention), Brazilian Studies Association.

Negotiating National Identity: Immigrants, Minorities and the Struggle for Ethnicity in Brazil (Duke University Press, 1999; Editora UNESP, 2001; Akashi Shoten, 2016) analyzes why, despite great ethnic and racial diversity, ethnicity in Brazil is often portrayed as a matter of black or white, a distinction reinforced by the ruling elite’s efforts to craft the nation’s identity in its own image—white, Christian, and European. I explore the role ethnic minorities from China, Japan, North Africa, and the Middle East have played in constructing Brazil’s national identity, thereby challenging dominant notions of nationality and citizenship.
By employing a cross-cultural approach, I examine a variety of acculturating responses by minority groups, from insisting on their own whiteness to becoming ultra-nationalists and even entering secret societies that insisted Japan had won World War II. I show how various minority groups engaged in similar, and successful, strategies of integration even as they faced immense discrimination and prejudice. Some believed that their ethnic heritage was too high a price to pay for the “privilege” of being white and created alternative categories for themselves, such as Syrian-Lebanese, Japanese-Brazilian, and so on. By giving voice to the role ethnic minorities have played in weaving a broader definition of national identity, this book challenges the notion that elite discourse is hegemonic.
Negotiating National Identity: Immigrants, Minorities and the Struggle for Ethnicity in Brazil was awarded the Best Book Prize, Latin American Studies Association-Brazil in Comparative Perspective Section.

Welcoming the Undesirables: Brazil and the Jewish Question(University of California Press, 1994; Imago Editora, 2005; Tel Aviv University Publishing Projects, 1997) tells the poignant and puzzling story of how, in spite of the power of anti-Semitic politicians and intellectuals, Jews made their twentieth century exodus to Brazil, “the land of the future.” What motivated the Brazilian government to create a secret ban on Jewish entry in 1937 just as Jews desperately sought refuge from Nazism? And why, just one year later, did more Jews enter Brazil legally than ever before? The answers lie in the Brazilian elite’s radically contradictory images of Jews and the profound effect of these images on Brazilian national identity and immigration policy.
