Prof. Darius Viržonis has been a leading figure in micromachining, nanofabrication, MEMS, and MOEMS research since 2004. His early work focused on developing surface micro- and nanomachining technologies, particularly for capacitive micromachined ultrasonic transducers (CMUTs) and sub-wavelength optical microstructures. In 2008, he co-founded Lithuania’s first semi-private, publicly accessible academic micro-nano fabrication lab at Panevėžys Mechatronics Center. At the time, it housed the most advanced cleanroom facilities in the country and became the technological foundation for his research group at Kaunas University of Technology. Presently, prof. Darius Virzonis is co-founder and CSO of Orius Tech Ltd and a professor at Vilnius Gedimino Technical University.
