Job summary

Culmen International is seeking a Senior Research Physiologist - Environmental Physiology and Data Science to turn research questions into executable protocols and lead analyses of multimodal datasets for government missions.

The role blends environmental physiology, wearable sensors, metabolic testing, and statistical programming to produce reproducible insights and scientifically meaningful findings for field deployments.

Qualifications

• Ph.D. in Environmental Physiology.
• Expertise in physiological responses to heat, cold, and high terrestrial altitude.
• Proficiency in R, SPSS, and/or MATLAB; ability to work with other languages.
• Experience designing or executing human-subjects field studies and collecting physiological data in environmental extremes.
• Experience with wearable sensors, large time-series datasets, data synchronization, data cleaning, and reproducible analysis.
• Experience with exercise/metabolic measurement and blood-gas analysis.

Responsibilities

• Assist principal investigators with protocol design, study methods, data-analysis plans, regulatory documentation, and responses to scientific or human-use review comments.
• Plan and support field studies in heat, cold, altitude, subterranean, and other operational environments, including site readiness, team assignments, equipment, communications, safety, and data-management procedures.
• Identify, configure, calibrate, and operate wearable physiological sensors and coordinate real-time collection and streaming of large datasets.
• Conduct or support maximal and submaximal exercise testing, metabolic measurements, resting ventilation, pulmonary-function testing, and sterile collection procedures for genomic testing.
• Operate clinical blood-gas analyzers such as NOVA Profile Plus, Radiometer, i-STAT, or comparable systems.
• Develop and maintain reproducible R, SAS, SPSS, or MATLAB programs for data curation, time alignment, cleaning, outlier assessment, analysis, and iterative dataset updates.
• Manage datasets containing millions of observations per participant while preserving raw data, device metadata, data rights, version history, and secure transfer requirements.
• Interpret results using environmental-physiology expertise and literature review, distinguish physiological signal from sensor artifact, and support development or validation of predictive models.
• Prepare written data analyses, journal-ready tables and figures, technical reports, manuscripts, posters, presentations, and briefings for scientific and operational audiences.
• Coordinate and lead multidisciplinary investigator teams during military field studies and mentor staff in approved collection and analytic procedures.
