After several stops at universities in Germany and abroad, I am a highly motivated engineer who loves to get to the bottom of things and does not lose sight of the practical side and applications. Transferring the knowledge and developing my staff and students in my courses and research activities are the most lovely thing in my heart. I love teaching and research is my best hobby. I have an excellent social intelligent and my communication skills are rather advanced. I have more than 60 international publications and I have supervised several PhD and M.Sc. successive students. I have chaired and co-organized several IEEE conferences and invited as keynote speaker as well. I am reviewer for several IEEE transactions and conferences in Antennas and Propagationa, Vehicles Technology and Communication societies.
