Aveliina Helm is an ecologist and conservation biologist with interests in development, persistence and protection of biodiversity. Her research focuses on (1) dynamics of biodiversity and provision of ecosystem services, (2) temporal delays in response of biodiversity to global changes, (3) species susceptibility to global changes based on their life-history traits and functional role in ecosystems, and (4) conservation and restoration of biodiversity and related ecosystem services. She actively participates in the initiation and development of habitat restoration and conservation projects in Estonia, provides scientific counsel for Estonian Ministry of Environment and Ministry of Rural Affairs regarding biodiversity-related issues and puts a lot of effort into communication of scientific and conservation topics to wider audiences in Estonia and abroad. Aveliina Helm also started and runs University of Tartu start-up company Nordic Botanical Ltd. that focuses on applying ecological knowledge for developing nature-friendly and sustainable landscape and urban design.
