In 1970, Albertas Čaplinskas began working at the Institute of Physics and Mathematics, LSSR Academy of Sciences (later State Institute of Mathematics and Informatics, now Institute of Data Science and Digital Technologies, Vilnius University), to which he remained faithful to the end. Started as a senior engineer, he became chief research fellow, head of the Software Engineering department. Prof. Albertas Čaplinskas wrote close to 200 scientific articles; is the author of 5 books.
