We anticipate opening up to two postdoctoral research positions in the Alaska Observatory funded by the Department of Defense. Each appointment will be for 2 years, with the possibility of an extension of an additional year, depending on performance. Following are some of the tasks anticipated to be undertaken by the postdoc
1. InSAR Data Processing and Analysis:
o Lead the acquisition and processing of spaceborne Interferometric Synthetic Aperture Radar (InSAR) data.
o Develop and apply advanced multitemporal InSAR techniques to monitor land subsidence and uplift with millimetric precision.
o Integrate InSAR data with Global Navigation Satellite System (GNSS) measurements for high-resolution deformation mapping.
2. Infrastructure and Hazard Mapping:
o Generate maps of infrastructure vulnerability and coastal inundation risks using InSAR-derived subsidence data.
o Assist in creating infrastructure damage exposure models, particularly focusing on permafrost degradation and its impact on DoD assets.
3. Coastal Inundation Risk Projection:
o Perform inundation modeling using coastal subsidence rates, sea-level rise projections, and high-resolution LiDAR topographic data.
4. Groundwater Storage and flow modeling:
o Use InSAR and hydrogeological data in combination with poromechanical models to estimate groundwater storage and flow changes.
5. Data Validation and Benchmarking:
o Validate subsidence models using independent GNSS observations and assess the accuracy of deformation maps.
6. Dissemination of Results:
o Prepare publications and presentations for national and international conferences.
o Collaborate with DoD personnel and stakeholders to ensure the effective application of the developed tools and data.
Ph.D. in civil and environmental engineering, mechanical engineering, mathematics, physics, earth sciences, or related fields.
Knowledge of SAR interferometry and application in permafrost and cryosphere studies.
The knowledge of inverse theory and signal processing.
Also, the candidate must have strong skills in technical programming languages such as MATLAB, PYTHON, or C++.
The successful candidate will be required to have a criminal conviction check.
