Research Biography
I am a nutritional epidemiologist. I have a clinical background (BSc, 2009) and quantitatively focused training in public health (MPH, 2012). I further expanded my expertise with degrees in nutrition (MPH, 2018), nutritional epidemiology (PhD, 2018), and Statistics and Data Science (MSc, 2024). Following my doctoral studies, I completed postdoctoral training in nutrition and sleep epidemiology from 2019 to 2021. I possess strong research and analytical skills, strengthened by extensive coursework, research experience, and short-term training in quantitative epidemiological methods, causal inference, data science, and biostatistics. My research in nutritional epidemiology aims to deepen our understanding of how diet influences population health, uncover causal dietary risk factors for chronic diseases, and inform targeted prevention strategies by leveraging advanced statistical, data science, and causal inference methods. I am currently an NHMRC Emerging Leadership Fellow (EL1), with a focus on the application of causal inference and machine learning in nutritional epidemiology.
