Joscha Legewie received his Ph.D. in Sociology from Columbia University in 2013. Prior to Harvard, Joscha was an Assistant Professor of Sociology at Yale University. His research focuses on social inequality/stratification, education, race/ethnicity, quantitative methods, urban sociology, and computational social science. He is especially interested in understanding social processes, mechanisms and patterns of social organization that lead to inequality related to race/ethnicity, gender, and socio-economic status. His current work focuses on the broader implications and social costs of law enforcement activity. As part of this research, he has looked at the effect of extreme violence against police officers on the use of police force against racial minorities in NYPD stop-and-frisk operations. Currently, he is working on various projects that examine the effect of policing on the educational outcomes and health of minority youth using large-scale administrative data. Other research focuses on the temporal and spatial dynamics that explain ethnic/racial relations and discrimination. As part of this work, he designed a natural experiment to examine the influence of terrorist events on the perception of immigrants across nine European countries. More recently, he used data from 7.7 million time and geo-coded 311 service requests to examine when and where New Yorkers complain about their neighbors making noise, blocking the driveway, or drinking in public to understand the conditions under which conflict emerges. His work builds on rigorous causal inference based on innovative, natural or quasi-experimental research designs with a keen interest in "big data" as a promising source for future social science research. It was published in the American Journal of Sociology, the American Sociological Review and other major journals. His work has received multiple awards from the American Sociological Association including the Outstanding Article in Mathematical Sociology and the Distinguished Contribution to Scholarship in Population award.
