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 malaria 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-seq to characterize the gut microbiome over time and associate its various components with growth and survival.

Other research projects

In addition to my PhD work, I'll also mention briefly some of the collaborating projects I'm involved in:

  • Transcriptome differences between urban and rural birds - (Watson et al. 2017)
  • Dual RNA-seq of mosquitoes infected with avian malaria parasites 
  • Expression of MHC genes using different techniques
  • Great Reed Warbler genome assembly
  • Sex-specific avian gene expression using transcriptomics

Previous research

  • Transcriptomics of outcrossing Arabidopsis lyrata - (Videvall et al. 2016)
  • Transcriptomics of the hessian fly - (Andersson et al. 2014)
  • Molecular identification of blood meals in biting midges - (Pettersson et al. 2013)
  • Monitoring butterflies using grid-based sampling - (Videvall et al. 2016)
