The Virginia Tech National Security Institute (VTNSI) seeks applications for a Postdoctoral Associate to conduct research in computational modeling and uncertainty quantification as part of a multidisciplinary research program. The successful candidate will help develop surrogate models of computational systems via both reduced-order and machine learning approaches and leverage Bayesian and other methods to estimate parameters, quantify uncertainty, and recommend new points for training or full-order model evaluation to improve models. The candidate will also contribute to the preparation of peer-reviewed publications and scientific presentations and will assist in mentoring students involved in related research activities. There will also be opportunities for travel to present in conferences and to participate in collaborations.

The position will contribute to a multi-institution, National Institutes of Health (NIH)- funded research project to better understand and predict women’s health outcomes by investigating how hormones shape the structure and function of vaginal tissue across the lifespan. The successful candidate will have the opportunity to collaborate with researchers in Mathematics and Mechanical Engineering at Virginia Tech as well as from several other institutions.

• Ph.D. in Applied Mathematics, Computational Science, Mechanical Engineering, Aerospace Engineering, Engineering Mechanics, or a closely related field. PhD must be awarded no more than four years prior to the effective date of appointment with a minimum of one year eligibility remaining.
• Due to the senstitivity of the work performed by the institute, position is restricted to US Citizens.
• Demonstrated experience in Bayesian inference, parameter estimation, uncertainty quantification.
• Demonstrated experience with computational modeling of physical or engineering systems.
• Experience with scientific programming using Python, MATLAB, Julia, C/C++, or similar computational tools.
• Demonstrated record of scholarly research, including peer-reviewed publications.

• Experience building and training artificial intelligence and machine learning models.
• Experience with common machine learning software packages such as PyTorch, Hugging Face, Jax, etc.
• Experience with active learning or Bayesian optimization.
• Experience with surrogate modeling of physical systems.
• Ability to work independently, take ownership of research activities, and contribute effectively to collaborative research.
• Ability to work effectively with undergraduate and graduate students and contribute to their research training and mentoring.
