* Predictive Risk Modelling.

## Current research projects

Since 2014, Vaithianathan's research has had a strong focus on predictive-risk modelling. Current projects include:
* Allegheny Family Screening Tool: Rhema leads the international research team that has developed this predictive-risk modelling tool which is used as a decision support tool by child welfare call screeners in Allegheny County, Pennsylvania, US.
* Douglas County Decision Aid: Rhema is leading the research team developing this predictive-risk model which will be used during child-welfare decision making. Unlike the Allegheny Family Screening Tool, this tool will not use fully integrated data.
* Health Education England Working Across Wessex MyDay Survey: Vaithianathan is overseeing the development and implementation of MyDay, a purpose-built online survey that collects anonymous data from up to 2100 trainee doctors about their workplace wellbeing.
