Research Quality and Impact

Describe  how your research has demonstrable quality and impact

''My h-index is 14 which is an author level metric to measure my productivity as a researcher and citation impact of my publications as a researcher. My top h cited research is my systematic literature review on ‘’Food environment interventions to improve the dietary behaviour of young adults in tertiary education settings’’ published in the Journal of the American Academy of Nutrition and Dietetics in August 2015. I have published in 'top' journals in the field of public health nutrition and they largely have impact factors between approximately 2.5 and 4.31. According to ResearchGate, I have an Research Interest Score of 410.7 which is higher than 85% of all ResearchGate members and higher than 92% of all members who first published in 2012. The Research Interest Score is an indicator of citations and social media generated regarding research publications and commentary.  Currently, there are 537 citations of my research outputs. 

I have presented my research, including as an invited speaker, at both national and international conferences, notably the Sydney Local Health District Allied Health Research Forum (2015), Dietitians Association of Australia Conference (2013, 2014, 2015, 2016, 2017, 2018 and 2019),  Dietitians New Zealand Conference (2017, 2018, 2019, 2020, and 2021), International Congress on Obesity (2014, and 2016), International Society of Behavioural Nutrition and Physical Activity Conference (2015, 2019, 2020, 2021 and 2022), European Congress on Obesity (2018) and International Congress of Dietetics (ICD 2020, postponed to 2021 due to COVID-19). Most recently, I was an invited speaker at the General Practice Continuing Medical Education conference in 2022. 

My main research focus is the development of public policy to support healthy eating, and my research has mainly focused on the food environment and its effect on young adult overweight and obesity. I have been responsible for a range of strategic research outputs which have underpin policy discussions and advocacy efforts around the improvement of food environments in tertiary education settings. I have led many projects that have made original contributions to the literature and expanded knowledge and practice in the area of population nutrition research. My research on food environments and its impact on energy-dense, nutrient-poor food consumption is widely cited within the nutrition community. I developed an online resource for broad dissemination, to large employers, governments, academic and vocational training institutions. This resource included simple, valid and reliable measurement tools and indicators to enable ‘health checks’ of organisational settings and a detailed and professional toolkit for implementing positive changes to organisational food environments. Outcomes of my research have been extensively reported on in print, radio and online media (for example, the Sydney Morning Herald, NZ Herald, the Australian, the Age, Radio NZ,, The Conversation and others).
