Postdoctoral application in soft matter physics: Liquid crystals with a twist

Research subject: Physical design of twisted liquid crystals, optical properties and applications in biomimicry

We seek a highly motivated applicant interested in questions about the research topics “Physics of chiral cholesteric liquid crystals: design, optics and structure” and “Biological liquid crystals with their biomimetic versions”.The experimental methods include a strong effort in the physical design of cholesteric samples with a complex twist by soft matter methods, associated with spectrophotometry, advanced optical microscopy and image analysis.

The post-doctoral work’s will consist of creating artificial versions comprising singular twisted structures with a: non-monotonous pitch; variable orientation of the axis of symmetry; double helicity; combination of several of these geometries. This development work will be accompanied by the study of the optical properties of biomimetic films and their small-scale structure, by electron or near-field microscopy in collaboration with experts in the field. 

At the end of her/his post-doctoral period, the researcher will be able to master the full chain: design of optical films of complex-twisted liquid crystals, elucidation of their chiro-optical properties and their structure determined by different microscopy techniques, by himself and in relation with specialists in the field. Depending on the progress of the research work, the activity may extend to prototyping in conjunction with researchers specializing in optical sensors and robotics. The research project is a multi-faceted research topic, the results of which could lead to an applied and topical problem, that of guiding a fleet of autonomous vehicles, with strong potential for valorization in academic and industrial circles.

The applicant must be strongly interested about experimental work and possess tenacity. (S)he will be autonomous and communicative, combining curiosity with a thorough education in physics, physical chemistry, or materials science. Prior knowledge and experience in soft matter physics or chemistry are solid assets. Knowledge in liquid crystal science is welcome but not required (the supervisor will provide the appropriate training). Prior quantitative research methods and practical work in labs would be beneficial. Good knowledge and understanding of materials physics and chemistry, including polarized light optics, spectrophotometry, and light–matter interactions are assets. 

Our offer:

Duration: 12 months (extendable period).

Work hours: Full time (35.0 Hours per week).

The earliest starting date for this position is Oct. 01st, 2024. 

The deadline to apply is 15th June 2024 but may be closed in advance as soon as an applicant corresponding to the expectations of the position would be selected. Applicants who have decided to apply are advised to do so without delay.

Please request detailed details by email to the supervisor.
