Evolutionary genomics of host-microbe interactions

My PhD thesis included ten papers in two different projects:
1. Genomic interactions between malaria parasites and avian hosts
2. The gut microbiome's influence on avian fitness and survival

Genomic interactions between malaria parasites and avian hosts

I used dual RNA-sequencing of birds infected with malaria parasites. Because I sequence the blood, this allowed me to analyse not only the transcriptome of the host, but also the transcriptome of the parasite simultaneously. Resulting in an unprecedented opportunity to evaluate real-time interactions between hosts and parasites.

The gut microbiome's influence on avian fitness and survival

Ostrich chicks can experience dramatic mortality rates due to disease. The development of a healthy gut microbiome seems to be a crucial step in the first three months of an ostrich.

I used 16S rRNA Illumina sequencing to characterize the gut microbiome over time and associate its various components with growth and survival.
