Background

Jenna Reps holds a PhD (University of Nottingham 2014) in Computer science, a MSc (University of Bath 2010) in Mathematical Biology and a BSc (University of Bath 2009) in Mathematics. Jenna’s PhD work focused on developing novel data mining solutions to identify adverse drug reactions in a large UK general practice database.

After her PhD Jenna was a researcher and lecturer at the University of Nottingham and then joined Janssen R&D in 2016.  Jenna Reps has over a decade of experience developing prediction models using large observational databases.  She is an active collaborator in the OHDSI (ohdsi.org) community, co-leads the PatientLevelPrediction workgroup and maintains a number of OHDSI R packages (https://github.com/OHDSI/PatientLevelPrediction , https://github.com/OHDSI/EnsemblePatientLevelPrediction  , https://github.com/OHDSI/OhdsiShinyModules ).  Her current focus is on researching best practices for prediction model development in large observational data and investigating ways to improve model transportability.

In the Health Data Science group Jenna is working on 1) large scale empirical investigations into the impacts of model design choices, 2) ways to improve model transportability and 3) counterfactual prediction methods.
