Biography
Elka Georgieva Nadjakova-Nikolova

Donation

Born

Elka Nadjakova was born in Sofia (21.05.1936)

She is the daughter of Georgi Nadjakov and Vera Postompirova-Nadjakova

Education

She graduated from the Russian High School in Sofia (1954) with a gold medal

She graduated cum laude from an industry oriented profile of physics at Sofia University (1954–1959)

She spent nine months specializing in the laboratory of solid state physics at the Paris Faculty of Science (1966-1967)

In 1967, she began to work as a volunteer at the Institute of Solid State Physics. In 1974 she started working on a dissertation on the subject of the Twyman effect and some of its applications. She received a PhD degree in physics in 1978

Professional Experience

Department of Physics, Technical University, Sofia

Assistant professor (1960-1964)

Senior Assistant Professor (1964-1973)

Chief Assistant Professor (1973-1979)

Associate Professor (1979–1996)

Donation

Professor Dr. Elka Nadjakova-Nikolova was the founder of the museum of physics at the Institute of Solid-State Physics. She and her husband Professor Nikola Nikolov made significant contributions to its present state. They have donated all personal documents and apparatus used by acad. Georgi Nadjakov, so that the legacy of the founder of the first Institute of Physics at the Bulgarian Academy of Sciences can be preserved forever. In 2014 the Museum of Physics was recognized as a historical site by the European Physical Society. Elka Nadjakova has also donated a large number of physics textbooks, reference materials and books

Teaching Experience

She has given lectures in physics to foreign students at the Higher Mechanical and Electrical Engineering Institute (Technical University) in Sofia

Awards

She has received an award for her activities as a member of the Society of Physicists in the People’s Republic of Bulgaria
