- Preferential attachment random graphs: I am interested in random graph models capable of producing graphs obeying power-law degree distribution. I am also interested in questions related to the random graph structures such as diameter, cliques, clustering…
- Random walks on random environments: I am interested in random walk models such that the walker may interact and modify its environments. Here I would like to understand the recurrence/transience dichotomy, ballisticity and other phenomena.
