PhD position in the development of life-like materials that learn, remember, and forget for use in soft robotics

Synthesize libraries of single-, dual-, and triple-switch polyurethanes (Stenhouse salt, DASA, and Spiropyran) via copolymerization and post-polymerization functionalization, and validate backbone integration by NMR, GPC, DSC, DMA, tensile testing, UV-Vis spectroscopy, and pump probe characterization. Design and characterize synergistic switching cascades (collaborative, competitive, and interdependent pathways) using time-resolved and spatially resolved spectroscopy, patterned illumination, and pH/thermal stimuli. Develop and validate logic maps for memory formation, consolidation, and selective forgetting, and translate these into training-recall-forgetting cycles on physical polymer films and bilayer actuators. Contribute to integrating learning materials into soft robotic bilayer actuators and, together with the wider team, demonstrate behavioral adaptation in autonomous soft robots. Collaborate with international partners

• Strong background in Organic Chemistry, Polymer Chemistry, Materials Science, or a closely related field

• Highly motivated, curious person who enjoys working at the interface of synthetic chemistry, materials science, and soft robotics

• Comfortable in a multidisciplinary, collaborative environment

• Highly proficient in spoken and written English

• Master's degree

• Previous experience in one or more of the following areas is required: Polymer/polyurethane synthesis and characterization, Molecular switches (e.g., photochromic, halochromic, or thermochromic systems), Standard analytical methods (NMR, UV-Vis, FTIR, and related techniques), Thermomechanical characterization of polymers (DSC, DMA, tensile testing)

• Experience with soft actuators or soft robotic systems is a plus but not required.
