Olsson presently works close with the centre’s leadership on organizational issues. His research focuses primarily on marine ecology, including research seabirds and marie ecoystems in the Baltic Sea and in polar areas.
Olsson holds a PhD in population ecology from Uppsala University (1995), with a thesis on king penguins’ breeding and feeding ecology at South Georgia in the Southern ocean.
Olsson was managing director of the Stockholm Resilience Centre between 2009 and 2019. He was interim CEO at EAT in Oslo parts of 2019 and 2020 and interim director at Global Resilience Partnership (GRP) parts of 2018 and 2019.
Between 2003 and 2008, he worked as programme director at Mistra (the Foundation for Strategic Environmental Research) where he coordinated funding and evaluation of programmes focusing on natural resources management. He also led Mistra’s work on generating new ideas and intelligence work.
Prior to his work for Mistra, Olsson have worked at several nation research councils in Sweden and for the Swedish Government Office as senior advisor to the Environmental Advisory Council (Miljövårdsberedningen).

Foraging behaviour in the Razorbill Alca torda during breeding was similar to that found elsewhere, aside from dive shape. The aim of this study is to investigate the foraging behaviour of Razorbills during the breeding season at the largest colony in the central Baltic Sea. We used a combination of global positioning system (GPS) and time-depth recorder (TDR) devices were used on Razorbills breeding on the island of Stora K...

Reproductive timing in many taxa plays a key role in determining breeding productivity, and is often sensitive to climatic conditions. Current climate change may alter the timing of breeding at different rates across trophic levels, potentially resulting in temporal mismatch between the resource requirements of predators and their prey. This is of particular concern for higher-trophic-level organisms, whose longer generation t...

They studied the at-sea distribution of two auks (Common Murre Uria aalge, Razorbill Alca torda), two gulls (Lesser Black-backed Gull Larus fuscus, Herring Gull Larus argentatus), and Great Cormorant Phalacrocorax carbo during the peak breeding season of 2014 around Stora Karlsö, the main Baltic Sea seabird colony. Simultaneously, they quantified forage fish abundance and distribution using hydro-acoustics and pelagic trawli...

The island of Stora Karlsö hosts the largest colonies of fish-eating seabirds in the Baltic Sea. However, recent and reliable estimates of the number of breeding pairs of the main species have been missing. Based on a complete census in 2014, we estimated the number of Common Guillemots Uria aalge to 15 700 pairs, more than half (up to 70%) of the Baltic Sea population. The number has almost tripled since the early 1970s and t...
