Cornell Lab of Ornithology
College of Agriculture & Life Sciences
Cornell University
Ithaca NY
The College of Agriculture and Life Sciences (CALS) is a pioneer of purpose-driven science and Cornell University’s second largest college. We work across disciplines to tackle the challenges of our time through world-renowned research, education, and outreach. The questions we probe and the answers we seek focus on three overlapping concerns: We believe that achieving next-generation scientific breakthroughs requires an understanding of the world’s complex, interlocking systems. We believe that access to nutritious food and a healthy environment is a fundamental human right. We believe that ensuring a prosperous global future depends on the ability to support local people and communities everywhere. By working in and across multiple scientific areas, CALS can address challenges and opportunities of the greatest relevance, here in New York, across the nation, and around the world.
The Cornell Lab of Ornithology is a global leader in ornithological research and biodiversity conservation and hosts a vibrant community of more than thirty postdoctoral associates working across a range of topics and scales. We strive to provide a supportive postdoctoral environment that fosters scientific discovery, collaboration, and professional development. The postdoctoral associate will be affiliated with the Center for Avian Population Studies (CAPS, https://www.birds.cornell.edu/home/center-for-avian-population-studies/), one of six programmatic units at the Cornell Lab. CAPS is the home of the eBird project, one of the largest sources of avian biodiversity information in the world. The eBird team is a collaborative and innovative group that includes staff with deep expertise in bioinformatics, statistics, and ornithology.
The postdoctoral associate will be advised by Dr. Laurel Symes (symes@cornell.edu), and will also have the opportunity to work closely with colleagues from other programs at the Lab of Ornithology and across Cornell University.
With over two billion observations from hundreds of thousands of participants globally, eBird is the world's largest community science initiative for biodiversity monitoring. eBird observations are used to infer relative abundance at scale, key for ecological study and conservation efforts. Audio recordings of bird calls and song, both from cell phones and dedicated recording devices, are also growing in scale, creating the potential to complement, extend, and expand human observations. However, a key challenge is translating imperfect, behaviorally-mediated acoustic observations into estimates of the number of individuals present.
We seek a postdoctoral associate to collaborate with us on developing approaches that translate acoustic observations into calibrated estimates of relative abundance and assessing how those estimates can complement eBird-based monitoring. The specific methodological direction will be shaped jointly, drawing on the successful candidate’s interests and expertise as well as the data and perspectives of collaborating teams. We are particularly interested in approaches applicable to single-channel recordings at broad scales, while recognizing that integrating multielement microphones, acoustic arrays, and other approaches may provide valuable calibration and validation. Together, we will evaluate approaches based on inferential validity, uncertainty, transfer across species, sites, and recording systems, and comparison with independent benchmarks.
The following examples illustrate potential avenues of research rather than a required work plan. They may be pursued individually or in combination, and we welcome other creative and strategic approaches.
We do not expect any single method to perform equally well across all species, environments, recording systems, or density ranges. We recognize that acoustic-based abundance estimation may ultimately require multiple complementary approaches that address different components of the acoustic observation process and provide different levels of precision across contexts. Identifying where and why different approaches succeed or fail—and determining the level of inference that different data can support—will itself be an important research contribution.
The incumbent will have access to multiple datasets, including passive acoustic data accompanied by strong labels, acoustic data from areas with substantial eBird activity, and the option to collect additional acoustic data if needed. In addition to these core resources, the postdoctoral associate will have access to raw eBird data (> 2 billion observations), the ability to engage with the eBird Status and Trends modeling team, access to high-performance computing resources, and opportunities to collaborate with researchers from other programs at Cornell University. In the proposed approach, we encourage applicants to draw on their demonstrated skills. Please reach out as needed with questions about available training data or other resources required for your proposed approach.
The postdoctoral associate will be a key contributor to envisioning and advancing biodiversity monitoring, particularly the ability to maximize the impact of acoustic data in the eBird monitoring framework. This position will help define the Cornell Lab's long-term research agenda at the intersection of community science, acoustic monitoring, and statistical ecology.
This is a one-year appointment, with extension for an additional year contingent upon available work and performance. This position is funded for 2 years. Additional extensions are possible contingent upon additional funding, work and performance. Funding will be provided for conference participation and other professional development activities.
As part of the training, the postdoctoral associate will gain experience working with researchers from different disciplines and will receive training in proposal writing, collaborative science, and translating research to application.
Working collaboratively, we will establish a focused and achievable set of research goals for the appointment, tailored to the successful candidate’s interests and expertise. Anticipated outcomes include a framework for benchmarking and validating acoustic estimates of abundance or density; the development and evaluation of one or more promising, scalable approaches; characterization of uncertainty and transferability across relevant species, sites, and recording systems; and reproducible code or analytical workflows. The postdoctoral associate will also lead or contribute substantially to peer-reviewed manuscripts, presentations, and practical recommendations for integrating acoustic information with eBird-based monitoring. The precise balance among these outcomes will be determined jointly as the project develops.
The incumbent will have opportunities to engage in undergraduate mentorship. There are no supervisory responsibilities with this position.
CALS hiring rate for this position is $65,000.
The position is based in Ithaca, NY, where personnel will have the flexibility to work on a hybrid schedule (4 days on site) with opportunities to work on-site and from home.
Benefits provided by Cornell include a broad range of comprehensive health care options, generous paid leave provisions: 3 weeks of vacation, 13 holidays (including end of year winter break), paid family leave, and superior retirement contributions. Additionally, Cornell provides access to professional development initiatives, wellness programs, and employee discounts with local and national retail brands.
