Rickard Ignell
The overall aim of my research group is to understand the chemical ecology, ethology and evolution of disease vectors.


We plan and promote basic research on the chemical ecology of disease vectors in accordance with societal needs, nationally and internationally, and apply this know‐how to develop novel surveillance and control tools. 

We use a multi-disciplinary approach to study how odour-mediated behaviours of disease vectors are modulated by external chemosensory cues and internal physiological states.


I obtained my MSc and PhD at the Department of Ecology at Lund University in 1996 and 2001, respectively. After 2 years as a postdoc associate/fellow at John Carlson's lab at Yale University, I obtained an Assistant Professorship through the Scientific Council (Vetenskapsrådet) and joined the Unit of Chemical Ecology at the Department of Plant Protection Biology. I became an Associate Professor in 2008 and was appointed Professor in 2011. As of 2012 I am the Head of Department of Plant Protection Biology.


I have supervised 10 PhD students to completion from 2008, and currently supervise 3 PhD students, Anais Tallon, Yared Desta (Addis Abeba University), Annika Hinze
