Our Polymer Digital Engineering Lab at the University of Wisconsin–Madison Department of Mechanical Engineering is expanding! We are seeking a talented postdoctoral researcher to develop and apply multiscale modeling approaches for polymers and polymer composites, spanning all-atom simulations, coarse-grained modeling, mesoscale methods, and potentially continuum-scale descriptions. Multiscale simulation has become an essential strategy for linking molecular-level chemistry and morphology to macroscopic mechanical, transport, and functional properties in polymeric materials and composites.
This role will focus on advancing predictive computational frameworks that connect molecular interactions, mesoscale structure formation, and bulk material performance. The successful candidate will work at the interface of polymer physics, computational mechanics, and data-driven materials modeling to understand structure–property relationships and accelerate the design of next-generation polymer systems.
Key Responsibilities
Perform multiscale simulations of polymers and polymer composites using all-atom, coarse-grained, and mesoscale modeling approaches.
Develop scale-bridging workflows to connect molecular structure, interfacial interactions, morphology evolution, and macroscopic material properties.
Investigate key phenomena such as chain dynamics, reinforcement effects, interphase behavior, transport, deformation, failure, and processing–structure–property relationships.
Build or integrate continuum-level constitutive or homogenization models informed by lower-scale simulations where appropriate.
Collaborate with experimental and computational researchers to validate models and guide the design of advanced polymer and composite materials.
Communicate findings through high-impact publications and presentations.
Preferred Qualifications
Education: Ph.D. in mechanical engineering, chemical engineering, materials science, physics, chemistry, engineering mechanics, or a related discipline.
Technical expertise: Strong background in molecular simulations, polymer physics, computational materials science, or mechanics of polymers and composites. Experience with atomistic simulation, coarse-grained modeling, mesoscale simulation, or continuum modeling is highly desirable.
Computational skills: Experience with simulation tools and scientific programming for multiscale modeling and analysis. Familiarity with data-driven modeling or machine learning is a plus.
Skills: Excellent problem-solving abilities, strong written and verbal communication skills, self-motivation, and a solid publication record.
Application Process
Interested candidates should provide:
Curriculum Vitae outlining academic background, research experience, and publications.
Cover Letter detailing your interest in multiscale modeling of polymers and polymer composites and highlighting relevant expertise across atomistic, mesoscale, and continuum simulations.
References for at least three professional contacts.
Please send your application materials to yli2562[A.T.]wisc.edu with the subject line “Postdoctoral Application – Multiscale Polymer Modeling”. We will begin reviewing applications immediately and will continue until the position is filled. Current UW–Madison postdoctoral openings commonly use titles such as Research Associate, Postdoctoral Fellow, or Postdoctoral Trainee, depending on appointment type.
Join us in advancing multiscale simulation frameworks for polymers and polymer composites, and in developing predictive tools that connect molecular design to bulk material performance. We look forward to welcoming a passionate researcher to our dynamic team at UW–Madison Mechanical Engineering!
