Georgia O'Callaghan

Director Analyst

I am a Director Analyst with the Analytics & AI team, lead by Carlton Sapp, specializing in business intelligence (tooling, self-service architectures, data literacy, self-service governance, etc.) and feature stores (a tool used in ML model development).

Previous experience

As a Data Officer at the National Institutes of Health I devised and implemented research and clinical data management procedures to increase research efficiency and ensure data integrity for high quality healthcare research. I provided leadership, management and training to a highly motivated team of research assistants and clinicians, instituting a cultural shift to adopt data governance procedures. In addition, I made weekly presentations to stakeholders about participant recruitment, study progression and patient treatment outcomes, leveraging insights from data through the coding of an automated reporting system in R.
