Welcome!

We study how global change factors alter interactions among ectothermic organisms (microbes, plants, invertebrates) and the implications on the structure and function of populations and communities.

Our research spans various organizational and trophic levels. Employing an integrative and interdisciplinary approach, our work encompass molecular biology, physiology, behavioral analysis, population and community ecology, as well as electrical engineering. Our results play a pivotal role in informing ecosystem management strategies.
