Postdoctoral Scholar - Arizona Tree Stress Explorer and Alert System - Computer Scientist
Job ID: 607103
Full/Part Time: Full-Time
NAU aims to be the nation's preeminent engine of opportunity, vehicle of economic mobility, and driver of social impact by delivering equitable postsecondary value in Arizona and beyond.
This position will primarily require working indoors at a computer. The position will require travel to present findings at research meetings, and to provide training sessions to stakeholders of the project, including ADFFM.
This position is renewable up to 3 years subject to availability of funding and performance.
This position is subject to the availability of funding. The incumbent is not eligible for Service Professional non-renewal notice, or Classified Staff layoff or recall status.
The Arizona Tree Stress Explorer and Alert System will provide near-real time, high spatio-temporal resolution assessments of tree health across all of Arizona. To provide this first-of-its-kind service at high spatial and temporal resolutions, the system requires high-throughput modeling of large amounts of satellite data daily to make tree stress predictions across a large spatial area. The models underlying the system will rely on in situ ecophysiological measurements of tree stress and leaf optical reflectance. The system will provide analytic results to the public and the Arizona Department of Fire and Forest Management (ADFFM) through interfaces designed by a leading firm. Use cases of the system will include early interventions for stressed forest stands and academic research on the determinants of tree stress, vulnerability, and intervention success. The successful candidate will be a member of a team composed of two postdoctoral scholars and one PhD student in addition to faculty mentors and participants.
The Gowanlock Lab at the School of Informatics, Computing, and Cyber Systems (SICCS) at Northern Arizona University's Flagstaff campus seeks a 3-year Postdoctoral Scholar to conduct research that will underlie the Arizona Tree Stress Explorer and Alert System. To enable near-real-time and high spatio-temporal resolution assessments of tree health in Arizona, the system must be capable of rapidly ingesting data and then performing in-memory parallel processing in shared-memory and distributed-memory environments. This computational infrastructure will be critical to realizing the near-real-time and high-resolution capabilities of the system. From a computational standpoint, the system will transcend the capabilities of other modern tree stress prediction systems and will lead to new and interesting computational challenges.
The successful candidate will be focused on parallel and distributed computing; we will also hire a postdoctoral scholar and PhD student focused on the ecological and remote sensing aspects of the project (see job 607104). The successful candidate will work closely with both the ecology postdoctoral scholar and PhD student. The successful applicant will have the opportunity to develop collaborations with ADFFM and other state actors in addition to the NAU community.
The postdoctoral scholar will serve as scientific lead on the parallel and distributed computing aspect of the project, with primary responsibility for guiding the intellectual development of the software infrastructure. Key activities will include: (a) work with the ecology postdoctoral scholar to ingest data from PlanetScope, ECOSTRESS, Sentinel-2, and Landsat, (b) work with co-PI Gowanlock on the design of the system, which will include performing parallel I/O in MPI, and designing scalable approaches for the data-intensive application, (c) assess scalability of the system as a function of several parameters, such as time between updates to global maps of model outputs, (d) incorporate features beyond the baseline components, including performing spatiotemporal queries on the data, (e) participate in marshalling the data into formats needed by the ecology team and public-facing interface.

. The report is a result of a federal law known as the Clery Act. The report includes Clery reportable crime statistics for the three most recent completed calendar years and discloses procedures, practices and programs NAU uses to keep students and employees safe including how to report crimes or other emergencies occurring on campus. In addition, the Fire Safety Report
is combined with the Annual Security Report for the NAU Flagstaff Mountain Campus as this campus has on-campus student housing. This report discloses fire safety policies and procedures related to on-campus student housing and statistics for fires that occurred in those facilities. If you would like a free paper copy of the report, please contact the NAUPD Records Department at (928) 523-8884 or by visiting the department at 525 E. Pine Knoll Drive in Flagstaff.
Salary range begins at $54,799. Annual salary commensurate with candidate's qualifications and related experience.
This position is exempt from the overtime provisions of the Fair Labor Standards Act (FLSA) and therefore will not earn overtime or compensatory time for additional time worked.
