Dr. Lauren Charles is a Veterinarian with a Data Science PhD trained in public health, epidemiology, and zoonotic diseases as well as mathematics, biology, environmental and geographic information science, plant pathology, and bioinformatics.
As a data scientist, her interests lie in identifying connections between living things and the environments they share through quantifiable data to promote public health security, environmental awareness, early warning, and understanding of infectious disease processes.

General Research / Expertise
Dr. Charles is a Veterinarian with a multidisciplinary Data Scientist PhD background with training in Mathematics, Biology, Environmental Science, Geographic Information Science, Plant Pathology, and BioInformatics. Current research combines statistics, machine learning, and deep learning methods for developing systems that support integrated, early warning for chemical and biological surveillance of humans, animals, and plants.
Her past research has focused on wildlife population health, epidemiology and ecology, and the interface between wildlife, humans, domestic, and agricultural animals. Dr. Charles’ current research integrates heterogeneous data sources, such as disease reporting with social and news media, natural disasters, meteorological and climatic data, behavioral and cultural factors, into complex epidemiological models to advance current biosurveillance through a one health approach. Her most recent work at Pacific Northwest National Laboratory focuses on One Health and National Security solutions in support of non-governmental organizations, the Washington Department of Health and the U.S. Departments of Energy, Health and Human Services, Agency for International Development, Defense, and Homeland Security.

Improving biosurveillance for human, animal, and plant health. In effort to improve biosurveillance for actionable decision making, my contribution has been to evaluate new data sources, integrate traditional and non-traditional sources, and develop new biosurveillance tools with cutting-edge analytics. Among my publications, I highlight a literature review showing promise for social media data as a “soft” data source to increase the speed of disease detection within a population. Building upon this, my colleagues and I have shown that social media data can be used to understand the health of populations. By combining social media information with other data, such as clinical diagnoses from medical reports (US Military) or disease case counts and natural disasters (Philippines), an analytic tool can identify when and where an outbreak may occur. In conjunction, I have focused research efforts on refining text analytics for biosurveillance from concept extraction to anomaly detection using various types of text-based data, e.g., news, online articles, social media, medical reports. These research efforts have founded open source global surveillance tools for human, animal, and plant health covering the biological and chemical domain.
Environmental and physiological influences on animal movements and disease patterns. In my research, I investigated the disease prevalence of Cryptosporidium in an enclosed, zoological population of Sifaka with known environmental, social, and physiologic factors. Here, environmental factors (i.e., temperature and seasonality) and physiological factors (i.e., age) correlated with oocyst shedding. In effort to understand environmental and physiological influences on cross-species disease transmission, I designed a database management integration system that utilized existing collared wildlife movement data (i.e., GPS and activity monitors), integrated it with weather station, drought, and severe weather reports, and overlaid it on a geospatially defined landscape map with geospatial analysis tools. This tool was utilized to understand how weather affected deer and coyote use of lowland cover and water resources and how weather, physiologic, and landscape correlated with their intra- and interspecies interactions. Also, I used the tool to identify relationships between specific weather conditions and aggressive interactions between wild mesocarnivores and humans, domestic, and/or agricultural animals.
Identifying factors that reduce nematode parasitism. My earliest work aimed to understand nematode-plant interactions and identifying methods to naturally protect important crop species from nematode invasion. The two biological control methods that I focused my attention on were 1) identifying natural resistance genes in plants to nematode invasion, and 2) characterizing the pathogenicity of a natural pathogen of nematodes. The work on plant resistance has led to the discovery of and characterization of root-knot nematode resistance in plants, which has been utilized in focused breeding efforts to naturally overcome nematode parasitism in important crop species, such as tomato, pepper, and soybean. Outcomes from research on the bacterial pathogen of root-knot nematodes led to 1) the discovery of new methods in bioinformatics for phylogenetic analysis (e.g., the advantage of multiple housekeeping genes over single 16S rRNA sequences for bacterial characterization), 2) the identification of the nematode parasite, Pastueria penetrans, as an ancestor to Bacillus sp., and 3) the identification of collagen-like motifs that could be key factors in bacteria-nematode pathogen interaction.
