Rheanna Mainzer

I am a Postdoctoral Biostatistician in the Clinical Biostatistics and Epidemiology Centre (CEBU) at the Murdoch Children's Research Institute (MCRI).

I research how to handle pesky missing data in observational studies. I also collaborate on research to improve the health and development of individuals born preterm.

Prior to MCRI, I was a Melbourne Early Career Academic Fellow at The University of Melbourne. I have a PhD in Statistics (inference after model selection), completed under the supervision of A.Prof. Paul Kabaila and Dr. Davide Farchione, and a Bachelor of Finance / Bachelor of Science (honours) from La Trobe University.

I have taught statistics courses across all tertiary year levels, and been involved with various outreach events and workshops.
