Research Interests

Most recently, my work has explored the ties between the environment, social factors and respiratory health. Two of my primary active projects include a study examining the association between stress and asthma among middle-schoolers, as well as the use of health applications for medication adherence for latent tuberculosis infection. My focus has primarily been on vulnerable populations, both in the US, on the border, and globally, in Vietnam, Mexico and Ghana. In my previous life in government, I conducted epidemiologic investigations to support disease control and outbreak management; and evaluated the effectiveness of disease surveillance activities.

Our expertise spans the following areas:

  • Infectious disease epidemiology
  • Tuberculosis (both active disease and latent infection)
  • Respiratory Health
  • Molecular epidemiology
  • Epidemiology in public health practice
  • Surveillance systems
  • Assessment of new technologies
  • Social epidemiology and health disparities
  • Global  and border health
  • Program evaluation, Monitoring & Evaluation
  • Climate change and respiratory health outcomes
  • Clinical trials
  • Multilevel/Hierarchical Models
  • Pilot & Feasibility studies
  • Systematic Reviews and Meta-Analyses

Current Project Areas

  • Feasibility of latent tuberculosis screening among migrant farmworkers
  • Adherence to Latent TB Infection among at-risk populations
  • Perceptions and social indices of walkability in Tucson, AZ
  • New technologies for latent tuberculosis infection
  • Climate change and respiratory health
  • Helicobacter pylori in Arizona
  • Stress and asthma in public schools
  • Biosurveillance and multi-drug resistant pathogens
  • Role of social media in infectious disease outcomes
