Interactions between malaria parasites and avian hosts

I use dual RNA-sequencing of birds infected with malaria parasites. Because I'm sequencing the blood, this allows me to analyse not only the transcriptome of the host, but also the transcriptome of the parasite simultaneously. This gives 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 use 16S rRNA Illumina MiSeq to characterize the gut microbiome over time and associate its various components with growth and survival.
