  • BRIEF CV

Dr. Dimov, Dimo Todorov was born in Bulgaria, in 1949.

He obtained his master in Cybernetics engineering at the Technical University of Sofia in 1973, his extra qualification in Applied Mathematics at the same University in 1974, and his Ph.D. degree in Informatics in 1979.

From 1979 to 1982 he was an employ of the Central development institute for computer science, in Sofia. From 1982 he works in the Bulgarian Academy of Sciences (BAS) in the areas of Computer Graphics and Databases (1982-1989), Informatics and Ecological Engineering (1989-1994), Image Processing and Pattern Recognition (1994-...). In 1991 he was elected as an Assoc. Prof. on Informatics, which position he holds in the Institute of Information and Communication Technologies (IICT) of BAS till now.

Besides his duties in the IICT research, he is also a visiting lecturer of the State University of Sofia (in spring semesters) and the New Bulgarian University in Sofia (in autumn semesters), in their master and/or bachelor programs, concerning the area of Image Processing and Recognition, since 1995 and till now.

Dr. Dimov is member of the Bulgarian Association of Pattern Recognition (since 1994), member of the editorial board of Cybernetics & Information Technologies J. of IICT-BAS (since establishing in 2000), and the scientific secretary of the international conference CompSysTech (since 2002), annually organized by Bulgarian Association of Lecturers in Computing, since 2000.

He is also Bulgarian representative in the South East European Transport Research Forum (SETREF), since establishing in 1997.

More than 100 publications in English, Russian or Bulgarian and, more than 20 successful projects are in his research and scientific activities in the areas of Image & Speech & Signal Processing, Pattern Recognition, Content Based Image Retrieval, Content Based Object Retrieval, Multimedia Databases, Medical Imaging, Computer Graphics, Data Mining & Information Retrieval Systems, etc.
