A number of years ago, while making house calls as a nurse practitioner to homebound, low-income elderly patients in West Baltimore, Sarah Szanton noticed that their environmental challenges were often as pressing as their health challenges. Since then she has developed a program of research at the Johns Hopkins School of Nursing on the role of the environment and stressors in health disparities in older adults, particularly those trying to “age in place” or stay out of a nursing home. The result is a program called CAPABLE, which combines handyman services with nursing and occupational therapy to improve mobility, reduce disability, and decrease healthcare costs. She is currently examining the program's effectiveness through grants from the National Institutes of Health and the Innovations Office at the Center on Medicaid and Medicare Services. She is also conducting a study, funded by the Robert Wood Johnson Foundation, of whether food and energy assistance improve health outcomes for low-income older adults. A former health policy advocate, Dr. Szanton aims her research and publications toward changing policy for older adults and their families.

Jordi Torrelles

Tuberculosis researcher and scientist

Texas Biomedical Research Institute

Tuberculosis, lung microbiome

Dr. Torrelles’ research is focused on the study of the human lung environment and its effect on the outcome of TB disease due to Mycobacterium tuberculosis (M.tb) infection. He also aims to improve the diagnosis of susceptible and drug resistant TB in high burden areas.

Beyond the diagnosis of TB, Dr. Torrelles and his team aim to understand the impact of the human lung mucosa in TB pathogenesis. He and his team have found that there are enzymes in the human lung mucosa that modify the bacteria prior to infecting host cells, thus, potentially redefining the M.tb pathway of infection and disease outcome.

Dr. Torrelles is originally from Catalonia, Spain. He received his Ph.D. in biochemistry/ microbiology in 2003 from the Autonomous University of Barcelona. During his graduate studies, he moved to Fort Collins, Colorado to serve as a visiting scientist at Colorado State University. He finished his Ph.D. and became a research associate and lab manager before moving to The Ohio State University for his postdoctoral fellowship, where over the years he became independent and obtained the appointment of tenured Associate Professor.

Joanne Turner, Ph.D., is the Vice President for Research at Texas Biomedical Research Institute. In addition to her administrative role, where she oversees the research functions of Texas Biomed, she also manages a research program. Her research focuses on immunology of Mycobacterium tuberculosis infection and immunology of aging. More specifically, she studies the changes that take place in the immune system during the natural aging process and how those changes can influence both innate and adaptive immune function when infected with M. tuberculosis. She also studies immune responses that correlate with an individual’s susceptibility to reactivate a previously latent infection with M. tuberculosis. Dr. Turner received her Ph.D. in Immunology from the London School of Hygiene and Tropical Medicine. She started with Texas Biomed this past summer, having previously served as a Professor and Biosafety Level 3 Program Director at The Ohio State University.
