Research Program:

What are your research interests?

I am interested in a broad range of statistical topics including:

  • Clinical trial design
  • Analysis of randomised trials with multiple outcomes
  • Regression modeling with applications in health systems
  • Statistical inferences
  • Longitudinal data analysis

Why did you get into research?

If you look at the social networks such as Instagram and Facebook, you would be able to find numerous pages advertising, and perhaps dangerously, prescribing non-scientific methods for weight loss, hair growth, increasing height, among other bizarre claims. Statistical research enables us to rigorously evaluate scientific hypotheses and generate evidence that allows consumers to have an informed decision.

The most succinct but elegant definition of statistics that I have seen is in the title of a book by J. Tall: “Statistics is reading between numbers.” I believe that statistics is a fascinating science that can help us to extract precious information hidden within the multitude of numerical data available to us.

My motivation in getting into research, particularly biostatistics research, is that I enjoy being able to use my data analytic and problem solving skills to help improve health and wellbeing in the community.

What would be the ultimate goal for your research?

My goal for research at HMRI is to support HMRI-affiliated researchers to design better studies, analyse their experimental data, decide how best to visualize and interpret the results, and collaborate in writing articles to describe the results of medical research.

I believe that real world problems give inspiration for academic research. My ultimate goal for research is to develop new statistical solutions to complex medical problems.


Sima has a long interest in statistical modelling and data analysis. She holds an undergraduate degree in Statistics majoring in Biostatistics. She is currently studying in Master of Medical Statistics at the University of Newcastle, expecting to graduate by the end of 2019.

In July 2019, Sima joined HMRI as a statistician for the Clinical Research Design, IT and Statistical Support (CReDITSS) Unit where she provides statistical consulting to HMRI affiliated researchers. 

Future Focus

As a biostatistician, my future focus is to progressively implement and develop statistical solutions to support researchers in the area of health and medical sciences.
