Serbia spent 0.9% of GDP on scientific research in 2017, which is slightly below the European average. Serbia was ranked 53rd in the Global Innovation Index in 2020, up from 57th in 2019. Since 2018, Serbia is a full member of CERN. Serbia has a long history of excellence in maths and computer sciences which has created a strong pool of engineering talent, although economic sanctions during the 1990s and chronic underinvestment in research forced many scientific professionals to leave the country. Nevertheless, there are several areas in which Serbia still excels such as growing information technology sector, which includes software development as well as outsourcing. It generated over $1.2 billion in exports in 2018, both from international investors and a significant number of dynamic homegrown enterprises. Serbia is one of the countries with the highest proportion of women in science.
