We’re looking for a Co-op in Applied Materials Research!

 About the Position:

This is a six-month co-op starting in July 2026 in the Research and Advanced Development group.  The Co-op will work directly with our scientists and will have the opportunity to get substantial research experience and to work independently on projects.

In this role, the candidate will contribute to the development of a comprehensive, physics-informed model that captures the behavior of electrophoretic pigments in next-generation ePaper systems. The primary objective is to build models that approximate:

• The dynamics of pigment motion under applied electrical waveforms (voltage vs. time)
• The resulting optical properties across different particle configurations and device states

This work will involve combining coarse-grained modeling approaches with data-driven techniques, including neural networks, to bridge multiple length and time scales. The candidate will collaborate closely with scientists to integrate simulation, theory, and experimental validation.

Tasks will be varied and include opportunities to learn about encapsulation technologies, make/modify pigments and test some of the display components as well as work with the final devices using the latest E Ink technology. 

The co-op must exhibit safe lab practices at all times and be capable of continuously learning new equipment and laboratory techniques. 

 Responsibilities:

• Develop multiscale and coarse-grained models to describe pigment behavior in electrophoretic systems
• Build physics-informed or data-driven models (e.g., neural networks) to capture pigment dynamics under applied electric fields
• Perform force field parameterization and optimization for particle-level simulations
• Simulate and analyze electro-optical responses as a function of waveform and material properties
• Conduct wet chemistry experiments to formulate and encapsulate ink systems (coacervation, UV-curable polymers, etc.)
• Test electrical and electro-optical performance of polymers
• Organize chemical property data of materials and work with scientists to design and carry out experiments
• Document the results of project landmarks and deliver project presentations to a technical community

Qualifications:

• Student pursuing a Master’s or Ph.D. in Physics, Polymer Science, Chemical Engineering, Chemistry or Material Science
• Strong background in physics-based modeling and simulation
• Experience with coarse-graining or multiscale modeling techniques
• Familiarity with neural networks / machine learning for physical systems
• Experience in force field development or parameter optimization
• Strong data analysis and programming skills (e.g., with Python, MATLAB, or similar)
• Strong materials characterization and data analysis skills
• Good technical writing and oral communication skills
• Good organization skills and the capacity to manage own schedule

Preferences:

• Understanding of colloids, soft matter physics, and surface science
• Experience with electrokinetics, colloidal transport, or particle dynamics under external fields (electric, magnetic, or flow fields)
• Hands-on experience with wet lab experiments and materials characterization
• Familiarity with electro-optical measurements or display technologies

 Benefits:

• Medical coverage
• 3.08 hours of ITO (Intern time off) per payroll
• 401(k)
• Casual day to day work environment
