Tyldum is a Research Professor at Fafo, with more than 20 years of experience from both applied and more academically oriented research projects. She has a particular interest in international migration and what shapes migration decisions, and she has worked extensively in Russia, Ukraine, and other countries in Eastern Europe.
Tyldum has published widely on migration in refugees populations, labour migration, and human trafficking, and has several publications on ethical and methodological challenges in research on vulnerable and hard-to-reach populations. She has led several major studies addressing policy responses and adaptations to high arrival numbers of refugees from Ukraine, with a particular focus on the interplay between the state, county, and municipal levels.
Since the full-scale invasion in February 2022, she has led several research projects aimed at understanding Ukrainian refugees and Russian migrants experiences in exile.
Tyldum is proficient in Norwegian, Russian, and English as working languages.
Labour migration | Poverty, vulernability and migration | Human trafficking | Political mobilisation and participation | Russia, Central and Eastern Europe | Survey design and sampling methods | Data collection for hard-to-reach populations
The project examines how municipalities, NAV employees, and the County Governors understand and implement regulations that restrict refugees’ ability to move during the first five years after settlement, and what consequences this has for refugees’ access to the Introduction Programme and social services.
This project aims to provide a better understanding about conditions for the "new Russian diaspora” – the large groups that have left the Russian Federation after the 2014 invasion of Crimea and, in particular, following the 2022 full-scale invasion of Ukraine.

Fafo will research the living conditions of unaccompanied minors in reception centres and how their care needs are met. The project will lead to recommendations on how UDI can ensure that all unaccompanied minors in reception receive proper care.
Fafo and Oslo Economics are conducting a project that will provide better insight into the causes and consequences of secondary migration among refugees settled in Norwegian municipalities. In general, we want to shed light on the connections between refugees‘ migration decisions, managed and dispersed settlement, and the municipalities’ integration measures.
Fafo will investigate the possibilities and limitations municipal authorities have for influencing the situation of migrants without legal residence, in five Norwegian cities.
In this project, MARE, we look at Europe's role in the management of migration and refuges in 4 areas, Amman in Jordan, the Bequaa Valley in Lebanon, Agades in Niger and Nakivale refugee camp in Uganda.
The phenomenon of EU migrants who go abroad to beg, collect bottles, trade and do other types of informal “street work” (Adriaenssen 2011) has featured on the political agendas of most European countries over the last decade.
