Research in the O'Donnell lab addresses questions at multiple levels of biological organization (individuals, social groups, and ecological assemblages) and across levels of causation (genetics, organismal and social physiology, nervous system development and plasticity, and the evolution of brains and behavior). Much of our work involves a strong field component; recent tropical field research sites include Costa Rica, Ecuador, and Taiwan. The lab uses a diverse array of social insects (army ants, paper wasps) and Neotropical birds as study organisms. Ongoing projects include:
Neurobiology and behavior- comparative analyses of brain evolution in arthropods; social insect caste differences in brain development
Thermal physiology of social insects- species and population differences in temperature tolerances across landscapes; individual differences within social groups; group-level thermoregulation
Ecology & behavior of mixed-species foraging groups- species differences in bird attendance of army ant raids; social and ecological interactions among birds at shared resources
Population genetics of the army ant Eciton burchellii, examining gene flow and landscape effects
Thermal and sensory physiology in alternative-tactic mating systems (Meghan Barrett, Ph.D. research)
Nutritional physiology and chemical signalling in social insects (Katherine Fiocca, Ph.D. research)
Human- and mammal-safe insect control- testing effectiveness of the polyalcohol sweetener erythritol as an ingested insecticide in social and solitary insects
Mathematical models of communication and division of labor in organized biological systems

O'Donnell lab news
New PhD student Karmi Oxman will be joining the lab this fall through the BEES department.
PhD students Meghan Barrett is conducting field research in the Sonoran desert on the physiology of alternative mating strategies in male bees.
Sean recently returned from teaching a Drexel field ecology course in Ecuador, followed by work with a natural history film crew in amazonian Peru.
Sean was awarded a Stein Fellowship to conduct thermal ecology research in the Negev Desert in Israel, summer 2019. He will be collaborating with Itamar Giladi at Ben Gurion University.
PhD students Virginia Caponera (talk) and Katie Fiocca (poster) presented at the 2019 Drexel Emergring Graduate Scholars Conference.
