Vessen Vassilev serves as an Associate Professor in the Department of Microtechnology and Nanoscience at Chalmers University of Technology, Sweden, where he has been affiliated since 1998. His academic journey began at Sofia Technical University before transitioning to Chalmers for advanced degrees and his current research leadership role. His educational qualifications include: M.Sc. in Radio Communications, Sofia Technical University, Bulgaria (1995) M.Sc. in Digital Communications, Chalmers University of Technology (1998) Ph.D., Department of Radio and Space Science, Chalmers University of Technology (2003) Professor Vassilev's research focuses on pioneering Monolithic Microwave Integrated Circuits (MMIC) for frequencies exceeding 100 GHz, with dual emphasis on circuit design and specialized packaging technologies. His work extends to millimeter-wavelength sensor development, most notably an automotive polarimetric radar system validated in real traffic conditions for road surface characterization—a breakthrough enabling differentiation between wet, icy, and dry pavement through advanced electromagnetic sensing. Analysis of his recent publications (2021-2025) reveals concentrated expertise in D-band/E-band communications, automotive radar applications, and innovative packaging solutions. Key thematic threads include road surface sensing using polarimetric techniques, high-speed wireless data transmission above 100 GHz, and gap waveguide antenna integration—demonstrating consistent contributions to next-generation millimeter-wave systems for both communication and safety-critical applications. He maintains active research within Chalmers' Microwave Electronics Laboratory, driving projects that bridge theoretical circuit design with practical implementation in radio astronomy heritage systems and emerging automotive technologies.
