Presentation
I am an ecologist with broad interest in biodiversity and the interactions of animals with their environment, including humans. I enjoy linking ecological and evolutionary theory with data, developing new analytical and data collection methods, and improving visualization of ecological data. I currently work with species such as large ungulates, saiga, eagles, swifts, elephants, zebras, bears and seals.
I also work on conservation issues worldwide, assisting with science and ground based conservation. Some of the agencies i regularly work with are UNEP-CMS, IUCN Species Specialist Groups, Saiga Conservation Alliance (SCA), UNDP, Snow Leopard Trust and many more. I am also the Coordinator of SILVA - The Faculty of Forest Science's Doctoral Research School.
