Thèmes de recherche

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. Je développe également des approches théoriques visant à modéliser des expériences au LOMA.

Jusqu’à présent, les thèmes suivants ont été abordés:

– Dispersion dans les milieux hétérogènes, notamment en présence d’obstacles

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

– Temps de contact dans les chaînes polymères

– Effets des parois sur la dynamique collective de robots autopropulsés

– Formation d’interfaces coniques entre deux fluides non-miscibles sous l’effet d’un laser

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

– Théorie des transitions conformationnelles des capsides virales

Trajectoire aléatoire partant d’un point source (étoile), trouvant finalement une cible sphérique.
