Current Research
As an entomologist, my primary focus lies in understanding how insects generate and use vibroacoustic signals and the various functions that these signals serve. Currently, I am investigating a species of caterpillar that initially lives in groups but eventually becomes solitary. Specifically, my postdoctoral research aims to understand how vibrations help these tiny caterpillars form groups, keep them together, and eventually split up. Additionally, I’m looking into how (or whether) these vibrations help caterpillars coordinate their activities when they’re in these temporary groups. By studying these aspects, I hope to not only learn more about how caterpillars communicate but also gain insights into broader questions about how insects interact socially.
