Idelle Cooper

Professor Cooper is interested in the evolution and ecology of phenotypic variation, particularly the selection pressures that lead to variation between sexes and between species. To study this, she investigates color and behavior of species in two damselfly genera, Megalagrion (an endemic Hawaiian radiation) and Calopteryx (Jewelwing damselflies of the mainland US and Canada).

Alongside studying the evolution of color and form in nature, Cooper also explores such variation through visual art, including painting and printmaking. She considers how the fields of visual arts and sciences have the potential to complement and enrich discoveries in each other.
