  摘 要  

The COVID-19 pandemic has incurred an immense human cost and socio-economic impact across the globe. It also demonstrated the importance of preparing for public health emergencies by harnessing the power of data, in particular, human mobility data that is strongly tied to the spatiotemporal spread of infectious diseases due to human contacts. Mobility data is sensitive and considered as personal identifiable information, Privacy enhancing technologies (PETs) become key enablers for developing data-driven solutions for pandemic preparedness via privacy-preserving data sharing and analytics.  In this talk, I will introduce several of our recent and ongoing efforts for supporting pandemic preparedness via PETs: 1) privacy-enhanced mobility tracking and contact detection to enable digital contact tracing; 2) mobility data collection with local differential privacy to enable accurate mobility pattern analysis; 3) mobility data synthesization to enable a variety of downstream epidemic modeling applications (with a highlight on our joint effort in generating synthetic datasets for supporting the 2023 US-UK PETS challenge for pandemic).  I will conclude with a set of open research questions.
