Birgit Koehler, PhD

Jag är miljövetare och arbetar med ekosystemanalys, ofta relaterad till klimatförändringar. För närvarande arbetar jag med olika frågor som rör Östersjöns och andra marina områdens tillstånd, hälsa och förvaltning, inklusive storskaliga mönster i biodiversitet i mänskligt påverkade ekosystem, hållbara akvatiska livsmedelssystem, havsbaserad vindkraft samt ekologisk design av artificiella strukturer i akvatiska ekosystem.
