Research Interests

I am interested in almost all areas of biostatistics and epidemiology, and their applications in health and medicine. I particularly enjoy working with large, complex datasets such as longitudinal datasets, large scale genomics data and linked administrative data.

Why did you get into research?

Since childhood, I have had a passion for both mathematics and medicine. When I discovered the field of biostatistics, it was an obvious choice. I love the constant challenge of this job. Researchers have a way of always bringing us new and interesting problems, requiring a combination of logical reasoning and lateral thinking to find optimal solutions.

What would be the ultimate goal for your research?

My core vision is to promote statistical excellence in medical research. When used appropriately, statistical approaches can provide valid answers to important questions. Alternatively, inappropriately used or selectively reported statistics can yield distorted or misleading results. It is rewarding to be part of large, collaborative teams committed to delivering quality answers to important health questions.

Biography

Dr Elizabeth Holliday is a Senior Lecturer in Biostatistics in the School of Medicine and Public Health at the University of Newcastle. She has training in mathematics and molecular bioscience (BSc Hons I), biostatistics (MSc) and genetic statistics (PhD).

Dr Holliday has a significant track record spanning genetic statistics and biostatistics. She has attracted $2.5 million in nationally competitive research grants/fellowships and produced over 100 peer-reviewed publications. She has strong expertise in large scale genetic studies of complex traits and has both led and contributed to international genetic studies, resulting in discoveries published in Nature (x3), Nature Genetics (x11) and Science (x1), plus a range of other quality journals.
