Introduction
PhD student in mass spectrometry and computational chemistry in the SACS team, at Institut de Chimie Radicalaire (ICR), supervised by Pr. Laurence Charles. I work on ion mobility for encoded polymers (on the mass spectrometry and computational side).
Master 2 Analytical Chemistry, Physics and Theory student since September 2020 at Sorbonne Université (ex-UPMC) (78%). Previously at Aix-Marseille Université, Master 1 in Analytical Chemistry and Spectroscopy (85%).

In the liquid state, vicinal J couplings (3J) have been extensively used for conformational analysis of organic compounds, peptides and proteins through the use of empirical Karplus equations. Contrastingly, there are essentially no examples of the use of 3J for quantitative structural investigation of solids. With the support of DFT calculations,...
The photodetachment energy threshold, as well as vibrationally-resolved spectral signatures of the lower lying excited states and dipole bound states in model aromatic phosphonate, sulfonate and phosphate oxyanions have been investigated using a photofragmentation spectrometer equipped with a cold ion trap. The effect of the laser excitation was mo...
Sequenced-defined poly(amino phosphodiester)s containing main-chain tertiary amines were synthesized by automated solid-phase phosphoramidite chemistry. These polymers were prepared using four monomers with different substituents. The formed polymers were characterized by...
The use of sequence‐defined polymers is an interesting emerging solution for materials identification and traceability. Indeed, a very large amount of identification sequences can be created using a limited alphabet of coded monomers. However, in all reported studies, sequence‐defined taggants are usually included in a host material by non‐covalent...
Solid‐state NMR spectroscopy can be used as a molecular goniometer for organic solids. In their Communication (DOI: 10.1002/anie.201906359), G. Mollica and co‐workers show that dihedral angles in organic solids are related to three‐bond 13C‐13C scalar couplings through a simple Karplus equation, thereby allowing molecular conformation in the solid...
Festkörper‐NMR‐Spektroskopie kann als molekulares Goniometer für organische Feststoffe eingesetzt werden. G. Mollica et al. zeigen in ihrer Zuschrift (DOI: 10.1002/ange.201906359), dass Diederwinkel in organischen Festkörpern durch eine einfache Karplus‐Gleichung mit dreibindigen skalaren 13C‐13C‐Kopplungen in Beziehung stehen, wodurch die Molekülk...
Konformationsanalyse per NMR: J-Kopplungen über drei Bindungen, die durch Festkörper-NMR-Spektroskopie organischer Feststoffe zugänglich sind, sind über eine einfache Karplus-Beziehung mit den Torsionswinkeln verknüpft. Diese Funktion stellt ein einzigartiges Werkzeug zur Untersuchung der Konformation organischer Materialien dar und sollte die Best...
Vicinal scalar couplings (3J) are extensively used for conformational analysis of organic compounds in the liquid state through the use of empirical Karplus equations. Contrastingly, there are no examples of such use for structural investigation of solids. With the support of first principles calculations, we demonstrate here that 13C‐13C 3J (3JCC)...
