Introduction and Current Research
I joined the faculty at UNL in 2013, shortly after receiving my Ph.D. from Duke University. I am also affiliated with the Rural Drug Addiction Research Center (RDAR) at UNL. My research interests include social networks, quantitative methods, inequality and drug use. I have done methodological work on network sampling and missing data, as well as more substantive work on network processes like homophily and status. My work has been published in the American Sociological Review, Sociological Methodology, Social Networks, Social Science & Medicine, as well as other venues. You can find detailed information on my publications (including links to the papers) on my website, as well as from my Google Scholars page. My website also includes information about the courses I have taught, including all of the materials from a recent seminar on network analysis.
My research explores methodological and substantive problems related to networks, individuals, and the broader social context. Methodologically, my work centers on a core problem in network studies: how can network structure be measured when there is incomplete information, either because there is missing data or because the data itself come from a sample. The larger agenda is to make it easier to specify and test theories based on a network view of the social world—where the complex interdependencies between actors are explicitly mapped, even with limited data. For example, I am currently working on a project that uses sampled network data to make inference aboutdiffusion processes. Substantively, my work pushes a contextual approach to studying social networks. The key question is how network features, like hierarchy, cohesion or group structure, vary across contexts, such as schools or neighborhoods. The larger goal is to analyze contexts, networks and individuals holistically: where contextual features, like demographic composition and economic inequality, shape network features, which, in turn, shape outcomes at the individual-level, like deviance or health.
I am also currently working on a new project on rural drug-use and networks. The NIH funded project will study the risk factors associated with rural drug use, looking at the social network dynamics and behavioral contexts that contribute to overdose risk and increased risk of addiction.
I am always looking for students to act as collaborators on projects related to networks, methods and social inequality. For example, I am currently collaborating with one graduate student (Sela Harcey) on a project that explores the effect of racial/ethnic classification on measures of stratification. We are also working on a project (with Robin Gauthier) on the relationship between isolation, cohesion and adolescent outcomes. I am also interested in collaborating with students with an interest in studying rural drug use, health risks and social networks.
I have taught a number of different courses at UNL, many of them core methods courses: Introduction to Social Research II (an introductory, undergraduate statistics course); Advanced Regression Analysis (a graduate level course covering categorical models); Social Networks: Theory, Methods and Applications (a graduate level course in networks); History of Social Theory (a graduate theory course) and Social Inequality (an undergraduate course on inequality). These courses include a diverse set of students, ranging from undergraduates only (Introduction to Social Research II), to a mix of undergraduate and graduate students (Social Inequality), to graduate only (History of Social Theory). The courses I have taught are also quite diverse in terms of material: from very technical classes to very theoretical classes to substantive courses to a mixture.
