CIRES / Chu Research Group, Postdoctoral Associate in Atmosphere-Space Lidar and Ionosphere-Thermosphere-Mesosphere Physics

About the Role

The Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder seeks a Postdoctoral Associate for the Chu Research Group. This role involves conducting interdisciplinary research using advanced resonance-fluorescence lidar observations and physics-based numerical modeling to investigate thermosphere-ionosphere metal (TIMt) layers and the coupled ionosphere-thermosphere-mesosphere (ITM) system. The position supports long-term observational programs at Boulder, Colorado, and McMurdo Station, Antarctica, aiming to advance the understanding of plasma-neutral coupling, atmospheric dynamics, meteoric metal transport, and upper-atmospheric variability.

This role integrates lidar observations with regional TIMt model development to explore metallic neutral and ion layers over polar and midlatitude regions. Research activities include scientific analysis of atmospheric observations, numerical model development, comparisons with whole-atmosphere and ionospheric models, publication in peer-reviewed journals, and presentations at national and international conferences. Opportunities exist to contribute to lidar instrumentation development, mentor students, and participate in field campaigns and proposal development.

Who We Are

CIRES is an internationally recognized leader in environmental science, partnered with NOAA since 1967. With over 900 professionals, CIRES advances understanding of the Earth system, including weather, climate, polar changes, air quality, and more. The Chu Research Group is a global leader in resonance-fluorescence lidar technologies, operating world-class lidar systems in Boulder and McMurdo Station, Antarctica. The group’s work focuses on atmospheric dynamics, plasma-neutral coupling, and long-term atmospheric variability.

Responsibilities

• Conduct independent research on thermosphere-ionosphere metal (TIMt) layers and the coupled ITM system using lidar observations, numerical modeling, and interdisciplinary analysis. (30%)
• Develop, improve, and apply physics-based regional TIMt models, integrating observational results with whole-atmosphere and ionospheric models. Publish findings in peer-reviewed journals and present at conferences. (30%)
• Contribute to the development, testing, deployment, and operation of advanced resonance-fluorescence lidar systems and field campaigns, including maintenance of the Golden Lidar Facility. (20%)
• Mentor graduate and undergraduate students and contribute to future research proposals. (15%)
• Engage in outreach activities and perform other relevant duties as necessary. (5%)

This is a one-year position with possible extension based on funding availability. Candidates must start by September 1, 2026, or as soon as possible thereafter. Opportunities may exist for field campaigns at McMurdo Station, subject to project needs and NSF requirements. The role involves collaboration with national and international researchers and occasional travel to conferences and meetings. A hybrid work arrangement may be available, though regular in-person participation is expected.

Requirements

• Ph.D. in Atmospheric Science, Space Physics, Physics, Aerospace Engineering, Electrical Engineering, Geophysics, or a closely related field. Candidates nearing completion of their degree will also be considered.
• Demonstrated research experience in upper atmospheric physics, ionospheric physics, atmospheric dynamics, remote sensing, meteoric metal layers, or related fields.
• Experience with scientific programming and data analysis using MATLAB, Python, or comparable languages.
• Experience analyzing large scientific datasets or developing physics-based numerical models.
• Record of publishing scientific research in peer-reviewed journals and strong communication skills.
• Ability to work collaboratively in interdisciplinary environments while conducting independent research.

Qualifications

• Strong knowledge of atmospheric and space physics, including the coupled ionosphere–thermosphere–mesosphere (ITM) system and upper-atmospheric dynamics.
• Expertise in scientific programming (MATLAB, Python) for processing, visualization, and interpretation of large datasets.
• Strong quantitative and analytical problem-solving skills for interpreting observational and modeling results.
• Ability to conduct independent research while collaborating in interdisciplinary teams.
• Excellent written and verbal communication skills for publications, proposals, and presentations.
• Strong organizational and project management skills to prioritize research activities and meet deadlines.
• Commitment to mentorship, teamwork, and fostering an inclusive research environment.

Preferred Qualifications

• Experience with resonance-fluorescence lidar systems, including observations, instrument operation, or data analysis.
• Familiarity with long-term lidar observations and analysis of TIMt layers or meteoric metal datasets from Boulder or McMurdo Station.
• Research experience in ITM coupling, upper-atmospheric dynamics, plasma-neutral interactions, or atmospheric remote sensing.
• Experience developing or applying regional/global atmospheric and ionospheric models (e.g., WACCM-X, TIEGCM).
• Experience integrating observations with numerical simulations to investigate atmospheric or space physics processes.
• Participation in field campaigns, instrumentation operation, or remote observations.

Benefits

• Comprehensive medical, dental, and retirement plans.
• Generous paid time off and tuition assistance for employees and dependents.
• ECO Pass for free local transit access.
• Robust training, professional development, and mentorship programs.

Pay

Annual salary range: $65,000 - $66,000, commensurate with education and experience.
