Privacy-protecting methods

TIDE’s portfolio of privacy-protecting analytic and data-sharing methods research, led by Sengwee Darren Toh, ScD, focuses on developing and applying cutting-edge analytic and data-sharing methods that integrate epidemiology, biostatistics, data science, and informatics to improve the validity, feasibility, and efficiency of multi-center studies, particularly in distributed data network studies that leverage routinely collected electronic health data.

Many of these methods support robust multivariable-adjusted statistical analysis without the need to share individual-level data, thereby providing better protection for patient privacy and confidentiality in multi-database studies.

Our guiding principles are:

  • Sending analysis to the data
  • Getting more (info) by asking for less (data)
