About me
I am an Associate Professor in Nature and Environmental Management, with a focus on Sustainable Development, here at the Department of Physical Geography.
My scientific interest lies in biodiversity and conservation challenges in a human-impacted, changing world. My main research focus lies in assessing how climate change and human activities alter structural, species and functional biodiversity of flora and fauna in natural and agro-ecological systems. I investigate plant-animal interactions and animal population management, human-wildlife coexistence and livestock impacts on rangelands across the world. I am interested in the shifts in nutrient cycling, carbon stocks as well as plant and animal species diversity and invasiveness in landscapes of various human land use pressure (e.g., corridors, buffer zones, protected lands and cultivated lands) that are also facing weather extremes triggered by climate change. I include socio-ecological aspects in my research as sustainable human-wildlife coexistence can only be achieved when local stakeholders are informed and participate in the decision-making process on resource use.
With my research projects, I address human-wildlife coexistence globally, particularly focusing on wild mammal species but also investigating livestock populations and their movement patterns in and around protected areas. My research spans across various spatial and temporal scales and addresses ecosystem functions and processes in temperate climates (Germany, Sweden, Italy), desert environments (Mongolia, Saudi Arabia), savanna systems (eastern and southern Africa), mountain regions (Andes) and tropical forests (China, Vietnam, Thailand, Tanzania).
