Creative Achievements
Developed a statistical model incorporating variability in work habits among workers and for an individual worker from day to day to achieve better respiratory protection for workers. Federal OSHA incorporated this framework for analyzing data and deriving assigned protection factors into their final rule on respiratory protection.
