ejuurista

Could you clarify what "ejuurista" refers to? I want to ensure I write an accurate, neutral, wiki-style article. For example, is it a real term in Finnish (or another language), a place, a surname, a concept in a specific field (linguistics, biology, technology, etc.), or a fictional/creative topic? Any context or sources you can provide will help, and I can tailor a concise entry under 300 words once clarified.
