Thrassos Panidis studied at the Department of Mechanical Engineering of the University of Patras, Greece, where he received his Diploma (1980) and Doctorate (1991). He worked in the same Department from 1980 initially hired as a Scientific Associate and was gradually promoted to the rank of Professor (2018). He also worked as a Visiting Researcher for one semester at Martin Luther University, Merseburg, Germany (1995). Since his retirement in 2023, he is an Emeritus Professor of the University of Patras.

For over 30 years, he taught courses in the fields of Mechanical Engineering and Aeronautics, focusing on fluid mechanics, heat transfer and turbulence, as well as experimental techniques and measurements, introducing new subjects based on the Department’s needs. He supervised a large number of undergraduate and diploma theses, while under his supervision, ten doctoral dissertations were completed, and two more are in the final stage.

His research interests focus on issues related to multiphase flows and heat transfer, turbulence, and combustion using experimental and computational techniques, with applications in energy, environmental, and aeronautical problems. He established the service laboratory of the Laboratory of Applied Thermodynamics in the field of material reaction to fire testing, accredited by the Hellenic Accreditation System, according to ISO/IEC 17025.

He has participated as a coordinator and researcher in a large number of research projects funded by Greek and International public and private entities, in collaboration with universities, research institutions, and companies in Greece, Europe, China, and Canada.

His research output includes more than 150 publications in international scientific journals and conference proceedings. His work on the development of a system of multiple microsensors thermal anemometer for measuring the velocity and vorticity vectors of flows led to a corresponding patent in collaboration with EADS.

He has organized and participated in the organization of numerous international and national scientific conferences and has served as a Guest Editor for two international scientific journals, and as peer reviewer for many other. He acted as Greek delegate in the European Committee EUROTHERM and was one of the founding members of the international associations ECATS AISBL (Environmentally Compatible Air Transport System) and EASN (European Aeronautics Science Network). He is a member of ERCOFTAC, EUROMECH, the Combustion Institute, and ELIPYKA (Hellenic Institute for the Fire Protection of Structures).

In addition to his administrative responsibilities at the Laboratory of Applied Thermodynamics, he has served the Department and the University in various leadership roles, such as Director of the University Lifelong Learning Center, member of the University Senate, Division Director, Laboratory Director, and member of numerous committees within the Department of Mechanical and Aeronautical Engineering and the University of Patras.
