Dr. McCullough has an active research, extension and teaching program in forest entomology. She works closely with natural resource agencies, Christmas tree growers and private landowners to identify impacts and contributing factors associated with damaging forest insect populations, and to develop long-term management strategies to conserve or enhance forest health. Research interests include invasive forest insect ecology, impacts and management; dynamics of forest insect populations; silvicultural and biological control of forest insect pests; and effects of disturbance on forest insect communities.

Current research projects
Emerald Ash Borer Biology, Ecology and Methods to Enhance Survey and Containment Efforts
Our studies address (1) the beetle’s life cycle including factors that influence larval development rate; (2) dispersal distance and pattern; (3) population dynamics and rate of spread; (4) host range and host preference; (5) effectiveness of insecticides for control of adult and larval beetles; (6) detection, survey and trapping technology; and (7) survival of life stages following treatments such as chipping, debarking and heat.
Spread and Impact of Beech Bark Disease
Objectives include (1) Annual field surveys identify the advancing fronts of beech bark disease in lower and upper Michigan; (2) Monitoring dynamics of beech scale populations; (3) Development of models to predict rate of spread of beech scale over time; (4) Long-term assessment of impacts of beech bark disease on species composition and wildlife habitat in affected stands.
Jack Pine Ecology and Management
Projects underway address the (1) influence of jack pine budworm defoliation and stand-related factors on jack pine mortality, volume and accumulation of coarse woody debris in northern Michigan; (2) abundance and diversity of carabid ground beetles in young, pole-sized and mature jack pine regenerated after fire, conventional harvest or whole-tree harvest.
Economic and Ecological Impacts of Invasive Forest Insects and Pathogens
Member of multi-disciplinary working group assigned to identify nonindigenous forest insects and pathogens established in the U.S., the economic impacts associated with major forest pests and effects of invasive forest pests on ecosystem services.
