Research and development (R&D) projects, national assessments and information for reporting directives (HD, BD, WFD, MSFD, MSP) related to marine biodiversity, marine spatial planning and marine protected areas, project leader and research coordinator. Leads international and national research projects on biodiversity, ecosystem services, marine spatial planning, identification and mapping of marine protected areas, alien species and the Ballast Water Convention.

Solvita Strāķe is Senior Researcher, chairperson of the Scientific Council and head of the Hydrobiology Laboratory of the Marine Monitoring Department. Solvita started her career at the foundation of LIAE, obtaining a BSc and MSc in Marine (Plankton) Biology. In 2009, she defended her PhD thesis on biodiversity and ecology of marine zooplankton at the Faculty of Biology of the University of Latvia and obtained a PhD in Hydrobiology. At the Latvian Institute of Aquatic Ecology (over 25 years of experience) as a senior researcher and international project manager, she has acquired deep knowledge in the fields of marine biodiversity, environmental monitoring, marine protected areas, non-indigenous species in Baltic Sea, biodiversity and marine spatial planning.
