Research interests

My research interests are in the understanding the relations between coevolving host and microorganisms. I work on invertebrate models across different types of interactions, from mutualism (mitochondria-host cell interaction) to parasitism (fungal and viral pathogens), using experimental approaches and next-gen sequencing.

Synthesis of transcriptome response of honeybees to fungal and viral pathogens:

My current project at sDiv consists on a synthesis of the transcriptomic response of honeybees to pathogen infections, using published and unpublished datasets. I explore the commonality in host responses, with the aim of understanding the role of pathogens in bee decline. To conduct this project, I organized two workshops (10th-11th October 2013; 28th-29th April 2014) where I invited bee scientists and bioinformaticians at sDiv, Leipzig. This project is coordinated by Prof. Robert J. Paxton (MLU Halle-Wittenberg) and Prof. Christina M. Grozinger (PennState University). Link to the project webpage: Trans-Bee   .

Ecology and evolution of host-pathogen interactions in the honeybee:

I am also interested in the dynamics of host-pathogen interactions in the honeybee, using both fungal (Nosema spp.) and RNA viruses. I am looking at the rapid adaptation of RNA viruses and their impact on honeybee decline. I also look at the impact of pathogen co-infections on host’s fitness and pathogen evolution and epidemiology. I also investigated the impact of pesticides on host-pathogen dynamics in the honeybee, and the effect of pesticide-pathogen interactions (additive, synergistic or antagonistic) on honeybee survival and colony decline.

Mito-genomics of Crustacean:

My PhD research was focused on the evolution of the mitochondrial DNA (mtDNA) of terrestrial isopods. This mtDNA present an atypical structure, including linear molecules, which is related to an exceptionally inherited heteroplasmy (co-occurrence of several mitotypes in the same individual), located on a transfer RNA gene, alloacceptor for two amino-acids. I studied the architecture, evolution and transcription of this exceptional mtDNA model.
