About this position

PhD position at Empa in Switzerland on life-like polyurethane materials for soft robotics. The project sits at the interface of organic chemistry, polymer chemistry, materials science, and robotics, with a focus on designing mechanically robust, multi-responsive polyurethane elastomers that can learn, remember, and forget through engineered molecular switching.

The successful candidate will synthesize and characterize semi-crystalline polyurethane elastomers containing backbone-integrated molecular switches such as Stenhouse salts, DASA, and spiropyran. The work includes copolymerization, post-polymerization functionalization, and validation using NMR, GPC, DSC, DMA, tensile testing, UV-Vis spectroscopy, and pump-probe characterization.

Research tasks also include designing synergistic switching cascades, studying collaborative/competitive/interdependent pathways, building logic maps for memory formation and selective forgetting, and translating these behaviors into training-recall-forgetting cycles on polymer films and bilayer actuators. The project further aims to integrate the materials into soft robotic bilayer actuators and demonstrate adaptive behavior in autonomous soft robots.

The position is hosted in the group of Dr. Luciano Boesel at Empa, under the direct supervision of Dr. Livius F. Muff, and the PhD student will be affiliated with ETH Zürich (Prof. René Rossi, D-HEST). The project is part of an SNSF Ambizione grant.

Eligibility highlights: a Master’s degree is required, along with a strong background in Organic Chemistry, Polymer Chemistry, Materials Science, or a closely related field. Applicants should be highly proficient in spoken and written English and have prior experience in polymer/polyurethane synthesis, molecular switches, analytical characterization, and thermomechanical testing. Experience with soft actuators or soft robotics is advantageous.

To apply, use the provided application portal and submit your materials through the Refline link. No deadline is stated in the post.

What's required

Applicants should have a Master's degree and a strong background in Organic Chemistry, Polymer Chemistry, Materials Science, or a closely related field. Strong spoken and written English is required. Prior experience in polymer/polyurethane synthesis and characterization, molecular switches (photochromic, halochromic, or thermochromic systems), standard analytical methods such as NMR, UV-Vis, and FTIR, and thermomechanical characterization such as DSC, DMA, and tensile testing is required. Experience with soft actuators or soft robotic systems is a plus but not required.
