Postdoctoral Scholar in Hyperspectral Remote Sensing of Invasion Ecology


Open June 12th, 2020 through Monday, Jul 20, 2020 at 11:59pm (Pacific Time)


A full-time postdoctoral scholar position in hyperspectral remote sensing of invasion ecology is available at the University of California Merced. The focus of this research is to study the ecosystem engineering impacts of water primrose (Ludwigia spp.) in the Sacramento-San Joaquin Delta, the landward end of the San Francisco Estuary. Water primrose is a highly invasive, non-native floating macrophyte in that, in recent years, has extended its niche into marsh habitat, causing extensive mortality of marsh vegetation. The goals of the project are to understand how water primrose invades and overtakes marsh as well as the factors that make marshes vulnerable to invasion. Hypothesized mechanisms include water primrose traits associated with growth strategy, its allelopathic properties, or factors related to marsh community structure. A main deliverable of the study is to identify and map the marshes most vulnerable to loss due to invasion and quantify the spatial trajectory of marsh loss due to invasion during the past 15 years. The postdoctoral position will be in the Earth Observation and Remote Sensing Lab in the Department of Civil & Environmental Engineering at UC Merced. The postdoctoral scholar will be based in Merced, California and will work under the supervision of the PI, Dr. Erin Hestir, in close collaboration with Dr. Shruti Khanna from California Department of Fish and Wildlife (CDFW) and scientists from the United States Geological Survey (USGS).

The postdoctoral scholar is expected to conduct field sampling for plant traits and community structure as well as analyze hyperspectral imagery collected from both piloted aircraft and UAV platforms. The postdoctoral scholar is expected to carry out research to map and quantify the spatial trajectory of marsh loss due to invasions and implement and develop research ideas to model and map landscape-level marsh loss vulnerability due to invasion with the guidance of the PI and Science Team. The postdoctoral scholar is also expected to write research articles aimed at disseminating the results obtained from the research and present results to the scientific community and other stakeholder groups at regional and national meetings. The postdoctoral scholar is expected to participate in team-based collaborative science with project partners including the CDFW and the USGS, play an important role in mentoring undergraduate and graduate students, and undertake professional development activities in consultation with the PI to further the training and career advancement of the postdoc.


A Ph.D. (at the time of appointment) in the physical sciences (ecology, plant biology, geography, environmental science, etc.) or engineering (environmental, aerospace, optical) with a focus on ecological remote sensing, geospatial analytics or modeling. Expertise in hyperspectral remote sensing, landscape ecology, and spatial modeling is ideal. The successful candidate will have demonstrated strong collaborative skills and will have at least 1-2 first author peer review research papers.

Technical skills include proficiency in programming for remote sensing image analysis, statistical modeling, graphics and visualization (e.g., Python, R, javascript), shell scripting and Linux command line tools. The ideal candidate will have experience with high performance computing for image processing, particularly for imaging spectroscopy, and geospatial analysis.

Interested applicants are required to submit 1) a cover letter indicating research interests and experience, 2) curriculum vitae, and 3) a list of three references with contact information including mailing address, phone number and e-mail address submitted through AP Recruit during the application process.

Salary is based on the University of California Academic Salary Scales. This is a full-time, one-year appointment with the possibility of renewal based on availability of funding, ongoing operational needs and satisfactory performance. Review of applications will begin immediately; position is open until filled with a final closing date of 07/20/20. Starting dates are negotiable but aims for August 1, 2020.
