Dr Grace Joshy

Fellow

Biography

Dr Grace Joshy is a Fellow within the Epidemiology for Policy and Practice Group at the National Centre for Epidemiology and Population Health. A biostatistician by training, she is experienced in population health research, and has high level technical expertise in analysing large population based studies and complex linked administrative datasets. She has particular interest in causal modelling and cohort studies, in particular survival models. Her current research focuses on chronic diseases, Aboriginal health, health service use and healthy ageing using the 45 and Up Study and its linked datasets. Recent projects include work with the Global BMI Mortality Collaboration (Lancet 2016), a landmark study on smoking and mortality in Australia (BMC Medicine 2015) and a commissioned project on the estimation of life expectancy of Australian men by age and health status for the Cancer Council Australia and Prostate Cancer Foundation.

She graduated with a PhD in Medicine in 2010 from the University of Auckland. Her PhD thesis, “Linking Existing Databases to Monitor and Improve Diabetes Care”, included a range of research projects including Ethnic Disparities in Causes of Death, Retention of Patients in the “Get Checked” Annual Review Program and Progression of Renal Disease among Indigenous and non-Indigenous People with Diabetes; her distinction in research led to awards including Kudos Hamilton Excellence in Research Award 2009 for Emerging Scientist Finalist and New Zealand Society for Study of Diabetes Professional Development Award 2008.

She is a chief investigator on four grants totalling nearly $1.3 million, an associate investigator on an NHMRC partnership grant worth $0.5 million and currently engaged in consulting work worth over $87,000. She also plays a major role in mentoring and capacity-building at the ANU through research supervision, postgraduate and short course teaching in Biostatistics and Epidemiology.
