Raphael Tizianis´ current research includes the development of novel diffusive gradient in thin film techniques for sampling and localizing root exudates from soil grown plants (DGT EXUDATES project). Moreover, he studies crop/model plants adaptations to abiotic stresses (e.g. iron or phosphorus deficiencies, copper contamination, microplastic stres) focusing on the interaction between the root, root exudates and the rhizosphere, as well as on the plants´ C fractionation. He is also involved in studying the soil carbon cycle in relation to the application of cover crops in apple orchards to increase the carbon sequestration potential of agricultural soils and their biological ecosystem services (SCOOP project). Furthermore, he is involved in studying the effect of microplastics on plants and soil, as well as extreme areas such as high mountains or the Galapagos Islands. 

He has also been involved in two Horizon Europe Mission Soil Projects, HuMUS – Healthy Municipal Soils (https://humus-project.eu/) and ECHO – Engaging Citizens in Soil Science: The Road to Healthier Soils (https://echosoil.eu/). In HuMUS he was mainly involved in the development and writing of “factsheets” with quick and easy methods to carry out soil health assessments as well as the development of a "territorial management agreement" about soil health; whereas in the ECHO project he was mainly involved in the co-creation workshops and in the development of the ECHO Soil Kit and Handbook writing.

He also actively engages in third mission dissemination by translating academic research into accessible formats for public policy makers and community stakeholders, considering also young citizen (<18).
