Overview Join the HJF Team! HJF is seeking a Physiological Data Modeling Computational Research Scientist II to support the Biotechnology High-Performance Computing Software Applications Institute (BHSAI). The mission of the BHSAI is to perform interdisciplinary research, combining physical, computational, and life-science research, to improve the efficiency and efficacy in the development of militarily relevant medical products for Force Health Protection. Research in this area focuses on the development of individual-specific mathematical models and artificial intelligence (AI) algorithms for preventing non-battle injuries, optimizing and enhancing Soldier performance, and optimizing casualty care. Research efforts in this area support military operational medicine and combat casualty care missions. For operational support, we are developing phenomenological, first-principle, and data-driven adaptive mathematical models to reduce the risk of heat injuries and improve mental activity in response to sleep deprivation. For casualty care, we are developing hardware and software platforms, as well as artificial intelligence-based decision-support algorithms, to improve the management of combat casualties in pre-hospital and in-hospital settings.
