Personlig profil
Forskningsintressen
I am a paleoentomologist with a broad interest in the evolutionary history of insects, particularly their morphological evolution, using techniques such as geometric morphometrics.
My current research investigates the evolutionary history of Lepidoptera (moths and butterflies) and Trichoptera (caddisflies), including their extinct stem-relatives. The project I am part of, as a post-doctoral researcher, seeks to unravel the diversification processes of these sister groups—one terrestrial and the other with aquatic larvae—and their responses to major historical events.
My previous research focused on the impact of biological crises on another aquatic insect order, the Odonata (dragonflies, damselflies, and their stem relatives), analyzing their morphological disparity patterns over time.
