Life scientists manage quality assurance programs and lead research related to human health protection. They study the effects of stimuli and other environmental factors on physiological processes, and the impact of microorganisms on human bodily functions and overall human health. They perform sanitation inspections to ensure military food safety, and provide consultation on issues regarding microbiological effects on subsistence. They assist in epidemiological investigations and direct training on food safety.

Military Training

Officers typically enter the Military after they have completed a four-year college degree; enlisted service members can transition to officer positions through a variety of pathways and earn a degree while serving. Job training for life scientists primarily consists of classroom instruction and on-the-job learning in various training environments. Like other officers, they complete a comprehensive training program covering responsibilities, military structure and etiquette, traditions, and leadership development. Job-specific training content may include:

  • Altitude physiology
  • Aero medical aspects of flight
  • Sensory physiology
  • Emergency egress
  • Water survival
  • Life support systems
