Objective: We seek to hire an outstanding researcher at the Ph.D. level to join our laboratory at the Institut de Chimie de Nice, Université Côte d’Azur. The successful candidate will be proposed and supported for a Ph.D. project on the emergence of homochiral biomolecules funded by a doctoral fellowship of the French Ministry of Higher Education, Research and Innovation.

Abstract: What is responsible for the emergence of homochirality, the almost exclusive use of one enantiomer over its mirror image? And what led to the evolution of life’s homochiral biopolymers, DNA/RNA, proteins and lipids, where all the constituent monomers exhibit the same handedness?

Our team is developing a synergistic methodology to build a unified theory for the origin of all chiral biological building blocks and their assembly into homochiral supramolecular entities. Multidimensional gas chromatographic analyses of astrophysical-relevant samples including interstellar ice analogues and meteorites will be combined with asymmetric photochemistry triggered by circularly polarized synchrotron and laser sources. To investigate the potential chirality transfer from chiral photons to prebiotic molecules, chiroptical data will be recorded in close collaboration with our colleagues at the Danish synchrotron facility ASTRID2. A unified theory on the asymmetric formation and self-assembly of life’s biopolymers will impact the conceptual foundation of the origin of life.

Background: Recent work central to the proposed research: i) Chiroptical activity of hydroxycarboxylic acids: implications for the origin of biological homochirality. Communications Chemistry 4, (2021); ii) Origin of alkylphosphonic acids in the interstellar medium. Science Advances 5 (2019); iii) Photon-energy-controlled symmetry breaking with circularly polarized light. Angew. Chem. Int. Ed. 53 (2014)
