Marzia Bisi

The main subject of my research activity is kinetic theory, not only for rarefied gases, but also for physical situations involving non-conservative interactions.
1) Kinetic theory for chemically reacting mixtures: kinetic models and hydrodynamic equations.
2) Kinetic theory for granular media: effects due to collision inelasticity.
3) Kinetic theory for socio-economic sciences: description of the interactions among agents, and of taxation and redistribution of the collected wealth.

Maria Groppi

My primary research activity deals with the kinetic theory of gases, in particular the dynamics of gas mixtures in the presence of non-conservative interactions, like chemical reactions, absorption, generations, inelastic scattering, presence of background host media (extended kinetic theory,generalized integro-differential equations of Boltzmann type). My present research activity includes also mathematical models in biomathematics, in particular the qualitative analysis of differential models in population dynamics and epidemiology (equilibria, stability, limit cycles, bifurcations).
