He employs various economic valuation methods, including the revealed preference (RP) method and the stated preference (SP) method. To date, he has worked intensively on more than 20 different international competitive and multidisciplinary research projects (e.g., H2020, Horizon Europe, Marie Skłodowska-Curie Actions, PRIMA, Interreg, EFSA, etc.) and more than 20 national and local projects. Based on his research findings, Dr. Rahmani published 20 scientific articles and a book chapter in various high-impact international journals.
