Instructors

Joshua Santarpia, PhD

Dr. Santarpia is the Research Director for Counter WMD programs at the National Strategic Research Institute,
Associate Professor of Microbiology and Pathology, and Program Director for Biodefense and Health Security
Degree Program at the University of Nebraska Medical Center. Dr. Santarpia is trained in aerosol physics,
atmospheric chemistry, and microbiology. His peer-reviewed research focuses largely on the fate of biological
aerosols in the atmosphere, detection of biological aerosols and atmospheric chemistry of biological and
anthropogenic particles. He has worked extensively to understand optical and other signatures that can
be used to detect and identify biological aerosol and studied how those signatures change over time. He
has developed novel methods to study bioaerosol hazard in medical environments, and studies for private
companies to determine potential aerosol hazards of medical devices in operating rooms. Most recently, he
has applied these methods to characterize SARS-CoV-2 aerosol in the patient environment and characterize
aerosol risk in public spaces.

Shanna Ratnesar-Shumate, PhD

Dr. Ratnesar-Shumate is an Associate Professor in the Department of Pathology and Microbiology at the
University of Nebraska Medical Center and is a Fellow of the National Strategic Research Institute for the
United States Department of Defense. Shanna has expertise on a range of topics including development
and assessment of bioaerosol sensors for early warning and detection; development of field portable and
autonomous bioaerosol sampling devices for collection of infectious pathogens in clinical and outdoor
settings; fate, persistence, transport, and dispersion of infectious aerosols in the environment; risk assessment
of biological agents; and evaluation of personal protective equipment for prevention of infection. Recently, she
has published several papers on the characterization of the SARS-CoV-2 in aerosols and droplets on surfaces.
She received her BS and ME in Environmental Engineering Sciences at the University of Florida and a Ph.D. in
Environmental Engineering Sciences at the University of Maryland Baltimore County.
