S. Scott Collis Fellowship in Data Science

The S. Scott Collis Fellowship in Data Science seeks applicants with a demonstrated background and interest in the interdisciplinary domain of data science. Collis Fellows in Data Science work at the junction of cutting-edge data science techniques and Sandia’s national security mission and application space. Data science at Sandia emphasizes the analysis and interpretation of scientific, engineering, and observational (sensor) data, including development of scientific models, pattern identification, prediction, and knowledge extraction. Relevant analysis techniques range from artificial intelligence to advanced statistical methods, to optimization techniques, to methods designed for specialized hardware, and beyond. Examples of the scientific and engineering applications relevant to Sandia’s diverse missions include nuclear deterrence and nonproliferation, numerical modeling and scientific simulation , energy systems and power grid, cyber security, operations research, geospatial analysis, neuromorphic computing , quantum computing, and many other national security domains.

The focus on data-driven insight through development of novel methods is central to the Collis Fellowship. We seek Fellows who will emphasize foundational data science research over work for which advances in data science are incidental to other topics.  For example, development of new data-driven methods to improve the quality of numerical simulations, or methods for analyzing quantum entanglement data, are both in scope for the Collis Fellowship.  However, applicants primarily interested in traditional computational and mathematical modeling should instead consider Sandia’s John von Neumann Fellowship, while those focused on development of quantum algorithms or architectures should consider the Gil Herrera Fellowship.

The S. Scott Collis Fellowship in Data Science is a prestigious postdoctoral fellowship that provides opportunities for highly motivated researchers to address challenging problems in national security applications. Scott Collis was the director of Sandia’s Center for Computing Research from 2017 to 2022.  Due in large part to his recognition of and advocacy for data science as a pivotal research area for impacting problems of national importance, the Sandia Data Science Postdoctoral Fellowship was created in 2021 to attract the best and brightest postdoctoral researchers in data science. The fellowship was renamed the S. Scott Collis Fellowship in Data Science in honor of Scott, who passed away in 2022 after battling cancer.  Scott’s vision will continue to be carried out through the innovative research of selected fellows working at the intersection of academic excellence and impactful applications.

Collis Fellows pursue a combination of both self-directed research in topic areas that they select, and integration with existing Sandia R&D projects, all under the guidance of Sandia staff mentors.   Collis Fellows are expected to publish the results of their work in leading journals and present research at top-tier conferences. Selected Fellows will receive a two-year appointment with the potential option for a third year, which includes a highly competitive salary, moving expenses, and a generous professional travel allowance.

Sandia National Laboratories is dedicated to nurturing a culture compatible with a broad group of people and perspectives. Consistent with this dedication, we seek applicants from a wide range of backgrounds, and we foster a research community of belonging.

To be considered for this fellowship, applicants must have completed, or be pursuing, a Ph.D. in a data science related area, including but not limited to mathematics, computer science, statistics, or engineering. The Ph.D. must have been conferred within the past three years or be completed by commencement of appointment. Furthermore, applicants must have appropriate research experience in one or more areas of data science. Evidence for expertise in data science may include a combination of formal academic training, research publications and presentations, development of open source or sharable software packages, and professional experience. Applicants should also have no previous postdoctoral appointments at a national laboratory and must be eligible to acquire a DOE security clearance, which requires US Citizenship.

Application process

Applicants should submit a one- or two-page summary, excluding references, of a data science research problem and proposed approach. We are interested in understanding the types of problems, data, and techniques that candidates hope to pursue during a potential fellowship.  Insights into how the proposed work may relate to national security problems are welcomed but not required.  If selected for the fellowship, the candidate will work with a Sandia staff mentor to align the proposed work to Sandia’s mission needs and expand the summary into a formal proposal for the funding that will support the next two years of their research at half-time.   The other half of the selected fellow’s time will come from an existing Sandia R&D project, giving the fellow the opportunity to collaborate on a research team.

To apply to the S. Scott Collis Fellowship in Data Science, please complete the following steps:

  • Read the complete Fellowship job description, including required and desired applicant qualifications.
  • Submit a single PDF file containing your cover letter, CV, and a 1-2 page research proposal when applying to Job ID 698738
  • Have three letters of recommendation sent to datasciencefellow@sandia.gov with “Collis DS Fellowship” as the subject line.

Applicants who are selected for on-site interviews should be available to travel during the weeks of January 18 and 25, 2027.

Complete applications received through November 30, 2026 will receive full consideration.

The S. Scott Collis Fellowship in Data Science is supported by Sandia’s Computing and Information Science Research Foundation (CIS RF). The CIS RF advances research and development in computing, mathematics, and information sciences to position Sandia at the frontiers and intersection of science, engineering, and national security. Collis Fellows work on interdisciplinary teams that span the CIS research areas and have access to cutting-edge computational resources.

Current Collis Fellows in Data Science

Eduardo Ortega, 2026 Collis Fellow

Eduardo Ortega is the S. Scott Collis Postdoctoral Fellow in the Scalable
Computer Architecture group at Sandia National Laboratories. His work focuses
on scalable resilient computing. His research interests lie at the intersection of
hardware and software for system-level robustness with a focus on efficiency and
scalability. His PhD dissertation focuses on lifecycle robustness and scalability throughout the computational stack, delving into a range of topics from circuits,
systems, to machine learning. He received his B.S./B.A. degree in Integrated
Engineering from the University of San Diego and his M.S./Ph/D in Computer
Engineering from Arizona State University (ASU).

During his Ph.D., Eduardo completed internships with Synopsys, Intel (x2), and Sandia National Labs. Eduardo has been awarded as the 2021 Sloan Scholar, 2022 National Science Fellow Graduate Honorable Mention, 2023 Fulton Fellow, 2023 Semiconductor Research Corporation TechCon Outstanding PhD presenter, 3x ASU outstanding research award winner, 2023 IEEE CAI Best Paper Nominee, 2x TVLSI impactful article, 2024 ASU ECEE outstanding graduate researcher, 2025 Qualcomm Innovation Fellowship runner-up, and the 2025 IEEE Circuits and Systems Society’s Outstanding Young Author.

As a S. Scott Collis Fellow, Eduardo is broadly interested in developing anomaly driven
monitoring systems to aid in runtime performance or quality control. With this project, he will develop and evaluate kernel-based learning methods for scalable image-based anomaly detection. The target application use-case is a resource-efficient anomaly detection to work in-situ for additive manufacturing process. Conventional deep-learning approaches, such as neural networks, typically require large datasets to learn and generalize effectively. In contrast, kernel-based methods can perform well in data-scarce, low-sample regimes. By leveraging existing kernel methods and developing new kernel similarity techniques, his work will construct unsupervised representations of known-good manufacturing processes. These “golden” process representations can then be compared with deployed processes at scale to assess manufacturing quality in
existing and emerging products.
