Predrag Mrdja actively participated in the international university competition Formula Student as a member of the University of Belgrade team in 2012, 2013, 2014, and 2016. In the early stages of developing the vehicle's powertrain, he was the chief engineer responsible for setting up the test bench systems and for testing and optimizing the engine control parameters. During the 2013 competition season, as mentor of the powertrain subteam, he led a group of students in designing and building the drivetrain system. In 2014, he served as leader of the University of Belgrade Formula Student team. During his involvement in the project, the team competed in the following events: Formula ATA, Italy (2012, 2013, 2014, and 2016) FS Czech, Czech Republic (2013) FSH, Hungary (2013 and 2016) FSA, Austria (2014) He also participated in the NI LabVIEW programming competition at the School of Electrical Engineering, University of Belgrade, in 2011 and 2012. Since 2016, he has been actively involved in international cooperation projects with AVL (Graz, Austria), the world's largest independent company for the development of powertrain systems. This collaboration enables the Department of Internal Combustion Engines at the Faculty of Mechanical Engineering to contribute to the development of future powertrain systems and to take part in research on a global scale. With funding approved by the United Nations Development Programme (UNDP), a gas supply station was commissioned in 2023, enabling the testing of engines fueled by gaseous hydrogen. As a result, the laboratory facilities of the Department of Internal Combustion Engines at the Faculty of Mechanical Engineering, University of Belgrade, are unique in Serbia and the wider region. From December 2021 to January 2025, he served on the exam scheduling committee of the Faculty of Mechanical Engineering, University of Belgrade. He has long served as Secretary of the Department of Internal Combustion Engines and as a member of the Department's inventory commission. He is also deputy coordinator of the Department of Internal Combustion Engines Alumni Club within the Faculty of Mechanical Engineering Alumni Foundation. His original professional contributions, including project leadership and participation, are reflected in his involvement in 20 international cooperation projects and 5 projects funded by the Ministry of Education, Science and Technological Development of the Republic of Serbia. As author or coauthor, he has published 6 papers in the M22 category, 24 papers in the M33 category, and 2 papers in the M34 category. He is the author of the supplementary textbook Mixture Formation and Combustion in Internal Combustion Engines: A Practical Guide (2025; ISBN 978-86-6060-219-2; 445 pages).
