My research area is conservation and management of marine mammal populations. The research includes all fields of basic biology and ecology of marine mammals, and applied science where I develop and test new methods to address anthropogenic threats such as fisheries bycatch. The aim is to find practical solutions to marine mammal conservation problems. My research focuses on populations of harbour porpoises, several dolphin species and humpback whales.

Research Interests

Examples of research activities:

1. Field and laboratory analyses to monitor marine mammal populations
I am involved in developing and using line transect and photographic identification methodology to study distribution, abundance and population size of cetaceans (porpoises, dolphins and whales). I conduct research to determine population structure using both biological and ecological markers (skull morphometrics, DNA analyses and pollutants). I also investigate the growth, reproduction and ecology of small cetaceans using biological data and stomach contents analyses. I am further involved in research studying behaviour of dolphins.

2. Develop methods to assess and mitigate anthtropogenic effects from fisheries and tourism activities on marine mammal populations (incorporating socio-economic issues).
The research involves both to identify the scale and impact of bycatch and to develop mitigation measures to solve the bycatch problem (e.g. by testing acoustic alarms on gillnets). The research is focussed on harbour porpoises in European waters, and several dolphin species and humpback whales in East Africa. I also study the potential effects from dolphin tourism activities on local populations of Indo-Pacfic bottlenose and humpback dolphins off Zanzibar and work on creating a sustainable dolphin tourism activity in this area.

Current Work

1. Conservation biology and ecology of the harbour porpoise and other marine mammals in the North Sea and adjacent waters.

2. Conservation biology and ecology of marine mammals (Indo-Pacfic bottlenose, humpback and spinner dolphin, and humpback whales) off Zanzibar, East Africa.

3. Conservation biology and ecology of sharks and other elasmobranchs off Zanzibar, East Africa.
