Title: Fighting COVID-19 at Cornell University

Abstract
Universities around the world faced a challenging decision during the summer of 2020: whether to reopen for in-person instruction despite the pandemic and how to protect campus populations if they did. Operations research and data science were a fundamental part of these decisions at Cornell University in the USA. First, models developed by Cornell’s COVID-19 Mathematical Modeling Team were used to design the testing interventions that are a cornerstone of Cornell’s COVID-19 control strategy: targeted asymptomatic screening that tests all undergraduates twice per week and an adaptive testing program that goes beyond traditional contact tracing to test the full social circle of positive cases. Second, these same models were the basis for Cornell’s decision to reopen for a fall semester with in-person instruction. They showed that reopening with aggressive mandatory testing was surprisingly less risky than virtual instruction. Data suggested that thousands of students would return to the area whether in-person instruction was offered or not, and a weaker ability to enforce mandatory testing for these students risked being unable to control clusters in that population. Reopening with asymptomatic screening was successful, with only 0.5% of students, staff and faculty infected over the semester. This talk will share insights from this experience and explain practical tools that supported this work.
