Mosquitoes are extremely good at finding and biting people, spreading various diseases in the process. But how exactly do they do this? While almost everyone has had mosquito bites, we know surprisingly little about this insect's behaviour. Biophysicist Felix Hol uses different approaches and techniques to better understand the mosquito and its interactions with parasites and viruses. He explores such questions as: how do malaria parasites move in the skin? How does a mosquito taste blood? Do viruses change the mosquito’s behaviour? Finding answers to these questions will help fight the diseases transmitted by mosquitoes.
