Petrovsky, Alexander Alexandrovich

A. A. Petrovsky graduated from Snovskaya Secondary School in 1970 ^[1] and entered the Minsk Radio Engineering Institute (MRTI), where he graduated with honors in 1975 with a degree in Electronic Computing Machines ^[2] . He began his career at MRTI as a junior research fellow ^[3] . Then he worked as an assistant in the department of computers. In 1977, he began his postgraduate studies at MRTI and three years later defended his thesis under the leadership of Alexander Efimovich Leusenko . Over the next 9 years (1981-1990), he held the position of assistant professor of computer engineering ^[4] . In 1985, he took over the management of the research laboratory of real-time microprocessor systems (MRTI). In 1989 he defended his doctoral dissertation on the topic “Construction of microprocessor systems for processing vibroacoustic processes in real time” (the defense took place at the G.E. Pukhov Institute of Modeling in Power Engineering, Kiev ). In 1990, he was elected head of the Department of Electronic Computing Tools of BSUIR , which he headed until 2017 ^[5] .

In 1983-1984 held an internship at Imperial College London (England). In 1994, he improved his qualifications at the Aachen Technical University (Germany). In 2000-2001 As a visiting professor, he worked at the University of Applied Sciences ( Mitweida , Germany). ^{[ significance of fact? ]}
