Mon activité de recherche actuelle vise à caractériser certaines propriétés de la dynamique stochastique d’objets complexes
(polymères, interfaces, assemblées de moteurs moléculaires) ou d’objets simples se mouvant en environnement complexe (comme un traceur dans un milieu hétérogène). L’approche développée est théorique, principalement au moyen de calculs analytiques, complétée par des simulations numériques et la résolution numérique des équations. Jusqu’à présent, les thèmes suivants ont été abordés:

– Dispersion dans les milieux hétérogènes

– Théories des temps de première rencontre pour des marches aléatoires à mémoire

– Temps de contact dans les chaînes polymères

– Dynamique collective d’assemblée de moteurs moléculaires : oscillations, mouvement bidirectionnel

– Théorie des transitions conformationnelles des capsides virales
