As an agricultural, environmental and food scientist, Galanakis' work is mainly focused on innovation and sustainability in the food industry, particularly more in the activity of "food waste recovery." The same research aims to high added-value compounds from wasted by-products in different stages of food production, re-utilize them in the food chain, and make bigger impact in achieving the Sustainable Development Goals (SDGs)—such as SDGs 2, 3, 6, 12, 13 and 15. This concept of "food waste recovery" was greatly highlighted in the advent of the COVID-19 pandemic which had greatly affected—among others—various global food production chains, food safety, food security, and environmental impacts caused by unsustainable food production around the world.
