Research interest

  • Conservation Biology
  • Nutritional Ecology
  • Population Genetics
  • Global Change Biology
  • Biodiversity Sciences

My main research interest is how human activities affect biodiversity in agricultural landscapes and how we can design practices to improve conservation. 

To address these questions I mainly work with insects, among them bees, fruit flies and aphids, studying their interactions with plants such as pollination and herbivory.

The main focus of my current work is:

  • How do wild bees and cultured honeybees health differs based on the type of wild flowers they consume?
  • How can we design better agro-ecological landscapes that support a healthy and large pollinator community?
