My scientific endeavors delve into the intricate relationships between environmental change, biodiversity, wildlife health, and the emergence of zoonotic diseases, guided by a holistic One Health perspective. Through meticulous investigation of anthropogenic activities, my research aims to elucidate how human-induced stressors impact species community assemblages, influence wildlife health, and shape the transmission dynamics of zoonotic pathogens.

Using a comprehensive approach, I evaluate the complex interplay between environmental change and biodiversity, including shifts in species community assemblages, genetic variations, and microbial diversity. Our findings underscore the pressing need for proactive measures to bolster ecosystem resilience and mitigate anthropogenic impacts on wildlife health.

One of my primary projects centers on understanding the effects of coronavirus infections on the microbiome in an African bat species complex. Through extensive collection efforts spanning thousands of bat tissue and fecal samples from caves across Ghana, we investigate gut microbiome composition and metagenomic functional diversity. By accounting for genetic background, co-infections, and environmental factors, we aim to discern the phylogenetic, environmental, intrinsic, and virus-related impacts. (Project: 'Effects of Corona and Astrovirus infections on the gut microbiomes of bats: the Hipposideros species complex as a model for virus-induced increase of pathogenic bacteria in highly gregarious mammals', DFG SO 428/17-1)

Through collaborative interdisciplinary efforts and the promotion of awareness regarding the interconnectedness of human, animal, and environmental health, we strive to advance our understanding of One Health principles and contribute to the development of sustainable solutions for global health challenges.
