Angeliki's research focuses on the role of food and nutrition in supporting health, independent living and healthy ageing, with particular expertise in food support within adult social care and in traditional dietary patterns. Her work spans public health nutrition, social care and gerontology, with a strong emphasis on translating research into policy and practice.

A major strand of her research examines food support for adults with care and support needs, using Meals on Wheels as an important lens through which to understand how food provision can support nutrition, wellbeing, social connection and independence. She leads an interdisciplinary programme investigating service provision, access, experiences and outcomes, inequalities in provision and unmet need, and how food support services can be strengthened and developed for the future. Her research combines qualitative and quantitative methods, evidence synthesis, co-production, intervention development and knowledge mobilisation.

Angeliki established Meals on Wheels UK, a national evidence, information and service-mapping platform designed to improve public access to services and connect research with providers, commissioners, policymakers and people with lived experience. Her research has informed local service decisions and national policy discussions and is increasingly developing international collaborations around food support and Meals on Wheels.

Her second major research area concerns Mediterranean and other traditional dietary patterns. Her work examines their definition and measurement, determinants of adherence, health and sustainability implications, and the development and evaluation of interventions to support dietary behaviour change. This research includes international collaborations and work on Mediterranean, Mexican, Chinese and African dietary patterns.
