CREAM cows at the farm

Please contact me for additional information. 

The Barlow Lab conducts research on dairy cattle health and disease. We conduct laboratory and on-farm experiments ranging across molecular, cellular, and population levels. Examples of the techniques we use include: basic microbiology, mammalian cell culture models, mathematical epidemiologic models, immunologic and molecular diagnostics, nucleic acid sequence analysis, whole genome sequencing, next generation sequencing, and bioinformatics.

Research:

In the Barlow lab, we study host-pathogen interactions and the impact of infectious disease control interventions (e.g. vaccination and antimicrobial use) on cattle health. Our work is motivated by practical concerns of dairy cattle health on food production, and encompasses epidemiology, molecular genetics, microbiology and immunology. We are interested in economically significant diseases of dairy cattle that affect productivity and ultimately human health and well-being through food availability. We also study epidemiology and host specificity of infectious diseases at the human-animal interface. Broadly, my research interests involve the intersection between epidemiologic and molecular genetic approaches to understand the population biology of host-pathogen relationships. Recently, our lab is exploring the use of next generation sequencing approaches (whole genome sequencing and metagenomics) in epidemiological studies of mastitis pathogens, antimicrobial resistant pathogens, and zoonotic pathogens on small to medium sized farms, including dairy farms that make farmstead and artisan cheeses.
