A senior restorer and document restoration expert at the Document Conservation and Restoration Unit of the National Library’s Information Resources Department. She graduated in Chemistry from Vilnius University in 1979. From this University, she obtained a doctorate degree in Chemistry in 2010 (the dissertation “The investigation of the degradation of inked paper and the evaluation of new conservation techniques”; supervisor Prof. Dr. Aldona Beganskienė).

She is interested in issues of written heritage preservation. The scope of her research involves reasons for the degradation of long-term preservation paper documents and the possibilities of stabilising paper by using alkaline compounds and antioxidants.

Currently she is involved in the study for determining the amount of alkaline material inserted during different alkalisation procedures and changes of this amount after the paper’s artificial aging.

She has published more than 20 articles on issues of conservation, restoration and care of library and archives collections.
