The anthropophilic Anopheles gambiae, opportunistic Anopheles arabiensis and zoophilic Anopheles quadriannulatus: Why do these sibling species display such different host preferences? Are the answers in their genome?


I am a postdoctoral researcher in the Disease Vector Group, led by Rickard Ignell and Sharon Hill in SLU Alnarp. I joined the group in 2018 and I am currently working on understanding the molecular mechanisms that underlie the divergence of host selection within Anopheles mosquitoes. I have had six years of research experience in the areas of cellular, receptor and molecular biology.


My research interest primarily focuses on the evolution of host preference within the Anopheles gambiae family complex. I am very interested in understanding how minor genotypic differences in odorant receptor genes between sibling species can alter the subsequent protein structure and cause a shift in host preference.

To expand our knowledge of the functional response of odorant receptors, I am interested in:

(i)   Studying the molecular mechanism of odorant receptors in response to host odours.

(ii)  Comparing the molecular profiles of odorant receptors between sibling species.

(iii) Identifying the functional sites that give rise to shifts in host preference.


I obtained my BSc in Plant Biotechnology from the University of Nottingham in 2010, where I performed research on the design and optimization of a novel method for quantifying transgene expression. I continued my research into the field of receptor biology, studying the signal transduction pathways of G-protein coupled receptors (GPCRs) in response to various chemical compounds. I earned my PhD in Biomedical Sciences in 2016 from the same university.
