Neha Lalchandani has a background in Food Science and Nutrition and is currently in her final year of studying for the Doctor of Philosophy (Public Health). She is working on a research project that explores the nexus between waste and nutrition in schoolchildren’s lunchboxes to improve dietary patterns while impacting the environment positively. This project has involved a mixed methods research design to review the literature, analyse school policies and programs, characterise lunchbox contents for food and packaging waste, and understand familial perspectives and practices. She has built a working collaboration with stakeholders from the Department for Education and environmental agencies like KESAB environmental solutions. This applied public health research project will serve as an evidence base to improve school food environments in South Australia and inform future policies and programs in this area. Neha is broadly interested in the socio-ecological influences on food choices and health behaviours, alongside pro-environmental behaviours for improving public health and sustaining planetary health.
