Analyzing the pathways of people who earned interdisciplinary research doctorates in the United States in 2010, we generate three main findings while controlling for gender, ethnicity, discipline, and age. First, individuals who complete an interdisciplinary dissertation display near-term income risk since they tend to earn nearly $1,700 less in the year after graduation. Second, students whose fathers earned a college degree demonstrated a .8% higher probability of pursuing interdisciplinary research. Third, the probability that non-citizens pursue interdisciplinary dissertation work is 4.7% higher when compared with US citizens. Our findings quantify the risks of interdisciplinary work and contribute to policy debates.
