MARK T. HERNANDEZ is a professor in the Department of Civil, Environmental, and Architectural Engineering at the University of Colorado at Boulder. His research interests lie at the cusp of molecular biology and civil engineering, including biological air pollution, sustainable industrial green chemistry, and biogenic acid production. Recent work has focused on tracking bioaerosols in the quarantined Katrina flood zone and in observing seasonal variation in biogenic aerosols in the urban Northeast and Mountain West United States. He attained his professional engineering registration after receiving all of his degrees and serving a post-doctoral tenure at the University of California’s Engineering College on the Berkeley campus. Dr. Hernandez currently serves as an editor of the Journal of Aerosol Science and Technology, and is the director of the Colorado Diversity Initiative.


BARBARA JOHNSON has over 15 years of experience in the U.S. Government in the area of biosafety, biocontainment, and biosecurity, and is president of the consulting company Barbara Johnson & Associates, LLC. She has managed the design, construction, and commissioning of a BSL-3 Aerosol Pathogen Test Facility, and launched the U.S. Government’s first chemical and biological counterterrorism training facility. Research areas include biological risk assessment and mitigation, testing the efficiency of respiratory protective devices, and testing novel decontamination methods against biological threat agents. In the private sector she pioneered the development of the first joint biosafety and biosecurity programs between the United States and institutes in the former Soviet Union.
