A GT CampusLife research team led by Profs. Munmun De Choudhury, Thomas Ploetz, Gregory Abowd, and other faculty members. As you may know, the GT contact tracers, the volunteer GT staff, are working hard to reduce the spread of COVID-19 in our community. They have explored new technologies that help contact tracers and found GT Eduroam Wifi log data can be useful for contact tracers. They are developing a prototype that can show the trajectory of places where a person who tested positive visited and the anonymized others who could have been in close contact with that person. The tool will only be used for contact tracing efforts and only when a person who tested positive agrees to the use of their Wifi log data.


They are aware of the sensitive nature of Wifi log data so they have closely worked with the GT Institutional Review Board (IRB) to assure that 1) the data is only used for research purposes; 2) the data is anonymized and 3) the research team will be able to identify individuals only if they consent to participate in this research. Please reach out to the Principal Investigator of this study, Prof. Munmun De Choudhury (, or the student-lead of this study, Dong Whi Yoo ( if you have any questions or concerns regarding this study.


They are seeking student volunteers who can act as mock COVID-19 positive cases so GT contact tracers can evaluate their prototype. The volunteer students will be asked to join a phone call lasting no more than 30 minutes with a GT contact tracer and another 30-minute follow-up remote interview with a research team member. To thank you for your time and effort, they will provide a $15 gift card.


In order to participate:

  • You must be 18 years old or older
  • You must be a Georgia Tech student
  • You must regularly use Eduroam when you come to campus
  • You must regularly come to an in-person class in February and March 2021


Please fill out this screening survey if you’re interested in participating in their research. Based on the screening survey results, they will reach out to you via the email address that you will leave at the end of the survey.
