During the COVID-19 pandemic, Joanna pivoted to work on risk analysis for test and trace programs, with a particular interest in digital tracing/notification strategies, and their potential for sophisticated risk analysis. The Masel lab is open to new students who want to work in this area, whether in preparation for the next pandemic, developing strategies for current endemic diseases (e.g. quantifying the circumstances under which non-pharmaceutical interventions could have advantages for specific subpopulations even when relatively ineffective at a whole-population level), or just intellectual interest.
As well as academic research, Joanna wrote some pieces and did interviews for the general public:
2022: Interview about COVID-19 risk assessment on Wharton Moneyball
2021: Blog post on "Health Equity and Exposure Notification Technology"
2021: Blog post on "How Effective is Exposure Notification in the United States?"
2021: Blog post on "What does the success of the NHS app tell us about other EN apps?"
2021: Blog post on "How many people need to use exposure notification for it to work?"
2021: Blog post on "Why do we believe that our exposure notification app will help?"
2021: Blog post on "How should exposure notifications account for new, more infectious strains?"
2021: Blog post on "Will exposure notification apps be useful for anything post-pandemic?"
2021: Blog post on "Now that vaccines are coming, is it still worth bothering with exposure notifications"
2020: Article with Peter Singer on "To Fight Covid-19 We Need Flexible Technology, Not Rigid Rules" Project Syndicate
And strange as it may be, I think the most-read thing I wrote at this time was a viral twitter thread about manuscript clearance processes and data use agreements at the CDC.
