The Eastwood laboratory aims to investigate the complex interactions between disease vectors, hosts, and their environment using a One Health lens.
Areas of Expertise
Field- and laboratory-based studies of vector-borne disease ecology. Enzootic transmission cycles of mosquito- and tick-borne pathogens. Vector ecology and surveillance. Sero-surveillance. Vector manipulation in BSL3 containment. Arboviral vector competency and transmission analysis. Ecological drivers of emerging infectious disease.
Eastwood’s area of expertise is the ecology of vector-borne disease, with a key focus on the transmission cycles of arboviruses and the emergence of infectious zoonotic diseases. She is passionate about One Health and approaches that recognize the integration of human health with animal, wildlife, and environmental health. Her current research interests include the host and vector ecology of novel arbovirus lineages; the vectorial capacity of invasive mosquito and tick species; and, the influence of tropical forest degradation on vector species diversity and pathogen dynamics.
· Emergence and spread of vector-borne pathogens.
· Co-infection of tick-borne pathogens.
· Arbovirus ecology, including (mosquito-borne) La Crosse virus and (tick-borne) Powassan virus.
· Ecological association of invasive disease vectors
· Drivers of emerging infectious disease, and impact of ecosystem changes such as deforestation.

ENT 6004 – Field Entomology Skills
With experience in vertebrate and arthropod fieldwork investigations, Dr. Eastwood co-instructs a graduate course on field entomology skills incorporating both field and lab-based elements. The course is hands-on, with a focus on study design, sample collection, sample processing, and data analysis as it relates to entomological surveys. Skills acquired during the class can be applied to research such as surveillance of disease vectors, crop insect monitoring, urban pest management, diversity index quantification and spatial distribution analyses.
