Diāna Ruska Academic position Associate Professor / Leading researcher Dr. agr. Field of research 2. Preservation of biological diversity in agro- and forest biocenoses, ecosystem protection and services 4. Development and adaptation of technologies for obtaining high-value agricultural and forest products, as well as in veterinary medicine E-mail diana.ruska@lbtu.lv Telephone +37129533945 Obtained doctoral degree in agriculture, sub-division livestock at Latvia Universoty of Life sciences and technologies. After 15 years working in the industry, she returned to the University and defended her doctoral thesis on 2014. She is an active senior researcher at the Institute of Animal Sciences in the field of cow milk production and quality since 2018. Her first leaded research project continued to explore previous fields of interest and was related to studies on nutrient conversion and optimal crude protein levels in dairy cow rations to reduce environmental contamination levels. In 2019 she was involved in ERA-NET cofounded the project “Climate care cattle farming systems”, and led of project in Latvia. Her interest in the full cycle of the milk production process and its impact on the environment become wider and more deeply studied. She is the author or co-author of 13 peer-reviewed publications indexed in SCOPUS, with an h-index of 3.
