Biostatistician & Nutritional Epidemiologist | R, Stata, Epidemiology, Health Data Analysis

Profile Summary

I am a public health researcher and biostatistician specialising in nutritional epidemiology and population health research. I hold a PhD in Public Health (Nutrition/Epidemiology) and have experience delivering rigorous, publication-ready analyses for academic, NGO, and policy-focused clients in Australia and low- and middle-income settings. My research focuses on dietary patterns, nutritional status, obesity, and nutrition-related non-communicable diseases, particularly among women and children. I have worked extensively with large-scale datasets such as DHS and NHANES, applying robust epidemiological methods to examine dietary diversity, anthropometric indicators (including MUAC), and malnutrition across populations. I bring strong expertise in biostatistics and health data analysis, with advanced proficiency in R and Stata for data management, survey-weighted analyses, multivariable and survival modelling, meta-analysis, and reproducible reporting. I have authored and contributed to peer-reviewed publications and collaborate effectively with multidisciplinary teams to translate findings into policy- and programme-relevant outputs. On Kolabtree, I provide support in: Nutritional epidemiology and population health research Biostatistical analysis and health data analysis (R, Stata) Systematic reviews and meta-analyses Study design, epidemiological methods, and protocol development Manuscript preparation, results interpretation, and reviewer-response support I am committed to delivering: Methodologically rigorous and transparent analyses Clear, publication-ready outputs Timely delivery aligned with client objectives and deadlines
