Ashley Hill, DVM, PhD 

Assistant Professor 


Ashley Hill is an Assistant Professor in Epidemiology in the Faculty of Veterinary Science at Colorado State University and an adjunct Assistant Professor in the Colorado School of Public Health.  After finishing veterinary training at the University of California at Davis (UCD) in 1998, she completed a Master’s degree in Preventive Veterinary Medicine (MPVM) in 1999, and a PhD in Epidemiology in 2003, both at UCD, both with emphasis on the epidemiology of breakdown injuries in Thoroughbred racehorses.

Her research interests are varied and currently include the effects of herd health programs on health and productivity in dairy cows, risk factors for racehorse injuries, antimicrobial use in dairy cows, infectious diseases in small ruminants, beef food safety, and simulation modeling of infectious and non-infectious animal diseases. 

Research Interests:
  • Veterinary Epidemiology
  • Stochastic Simulation Modeling
  • Injury Epidemiology & Prevention - Race horse injuries
  • Infectious Disease Epidemiology
  • Zoonotic Diseases
  • Food Safety
Courses Taught:
  • Epidemiologic Simulation Modeling
  • Veterinary Epidemiology
  • Preventive Veterinary Medicine
Current Research Projects:
  • Efficient Management Strategies for a Contagious Animal Disease Outbreak: Probability Distributions of Economic Impacts from Foot-and-Mouth Disease: Stochastically simulate outbreaks of Foot and Mouth Disease in the central United States, and use the range of outputs to describe the range of economic impacts that could result from FMD outbreaks in this region.
  • Description of interstate poultry movements for improved simulation modeling of highly-pathogenic avian influenza: Describe the frequency and distance that live poultry are shipped into Colorado from other states.  The information will be used to better parameterize simulation models for infectious avian diseases.
  • Indices for health and antimicrobial use in Danish dairy cattle participating in the New Herd Health Program: Use existing data to record morbidity, mortality, and medicine use parameters in dairy herds participating in the New Herd Health Program.  Combine these parameters into indices summarizing health and antimicrobial use that can be used to compare herds, and to track progress in herds over time.
  • Zoonotic disease and infection control training for animal shelter workers: Report animal shelter worker knowledge about infection control; zoonotic disease signs and transmission; and zoonotic disease signs and transmission before and after a training program.
