Centre for Integrative Biodiversity Discovery

My research focuses on ichthyology, freshwater biodiversity, conservation, and ecology, but I also work actively in urban biodiversity and bioeconomy. Browsing through my publications will give you an idea about some parts of my interests and expertise.
