      abstract     = {Suspensions of ionic microgels are of fundamental and
                      technological interest, owing to the sensitivity of the
                      microgel sizes to external control parameters such as
                      concentration, ionic strength and temperature. In this talk,
                      I report on a theoretical study of crowding effects on
                      thermodynamic, structural, and dynamic properties of
                      concentrated suspensions of ionic microgels, which gives new
                      insights into microgel deswelling effects.Methods for
                      calculating the crowding-dependent microgel radius are
                      discussed, used for the calculations of an effective
                      microgel pair potential from which thermodynamic, structural
                      and dynamic suspension properties are determined. It is
                      shown that deswelling mildly enhances self- and collective
                      diffusion and the osmotic pressure, lowers the suspension
                      viscosity, and significantly shifts the suspension
                      crystallization point to higher concentrations. In a
                      nutshell, a versatile bottom-up approach for computing
                      suspension properties of crowded ionic microgels is
                      presented based on the characteristics of single microgels.
                      If time suffices, I will also discuss pros and cons of
                      different colloidal charge-renormalization methods based on
                      the Primitive Model and Poisson-Boltzmann spherical cell
                      models, and the possible occurrence of an effective colloid
                      charge larger than the bare one.},
