معرفی
Rimantas Pupeikis is an Associate Professor and Affiliated Scientist at Vilnius University's Institute of Data Science and Digital Technologies (DMSTI), formerly known as the Institute of Mathematics and Informatics (MII). He is affiliated with the Global Optimization Group within the institute and has maintained a long-standing academic career spanning several decades.
Dr. Pupeikis graduated in 1969 from the Faculty of Mechanical Technology at the Vilnius Branch of the Lithuanian State Industrial University, specializing in Complex Mechanization and Automation of Machine Production. He earned his Doctor of Technical Sciences degree in 1979 from the Scientific Council of KPI and was awarded the pedagogical scientific title of Associate Professor in 2000 by the Scientific Council of VGTU (Vilnius Gediminas Technical University).
His research focuses on recursive identification of feedback dynamic objects, nonlinear systems, Wiener systems, delay identification, and dynamic object management. His work centers on the development and applications of the theory of identification and control of technological processes. Dr. Pupeikis has published extensively on system identification, signal processing, and control theory, with particular emphasis on adaptive tracking methods, convolution algorithms, and identification of nonlinear systems.
His publication record shows a consistent research trajectory with significant contributions in the 2010s and 2020s, particularly in the areas of adaptive joint tracking of system parameters, revised convolution methods, and identification of nonlinear systems with time delays. His work demonstrates a strong mathematical foundation combined with practical applications in signal processing and control systems.
Dr. Pupeikis has also been involved in pedagogical activities, teaching Digital Signal Processing and Databases at the VGTU Faculty of Electronics, delivering both lectures and exercises in English and Lithuanian.
His professional career includes positions as Junior Researcher, Postgraduate Student, and Researcher at the Institute of Physical and Technical Energy Problems (1969-1979), work at the Department of Technological Process Control at MII starting in 1980, research at the Department of Mathematics, Institute of Mathematics, University of Bayreuth (1996-1998), and research at the Department of Automatic Control and Communication Systems at Linköping University (2002-2003).
